Description

表示装置及び方法、並びにコンピュータプログラムDisplay device and method, and computer program
　本発明は、例えばＤＶＤプレーヤやＢＤプレーヤ等の任意のコンテンツを表示可能な表示装置及び方法、並びにコンピュータをこのような表示装置として機能させるコンピュータプログラムの技術分野に関する。 The present invention relates to a display device and method capable of displaying arbitrary content such as a DVD player and a BD player, and a technical field of a computer program that causes a computer to function as such a display device.
　主映像、音声、副映像などのコンテンツ情報や再生制御情報等の各種情報が記録された光ディスクとして、ＤＶＤやＢＤ（Ｂｌｕ－ｒａｙ　Ｄｉｓｃ）が一般化している。このようなＤＶＤやＢＤによれば、例えば一本の映画について、ステレオ音声或いはサラウンド音声の他、オリジナルの英語音声、日本語版吹き替え音声、…などの各種音声や、例えば、日本語字幕、英語字幕、…などの各種字幕（或いは、その他のデータ）が多重記録されている。 DVDs and BDs (Blu-ray Discs) are commonly used as optical discs on which various information such as content information such as main video, audio, and sub-video and playback control information is recorded. According to such a DVD or BD, for example, for one movie, in addition to stereo sound or surround sound, various sounds such as original English sound, Japanese dubbed sound,..., For example, Japanese subtitles, English Various subtitles (or other data) such as subtitles,...
　又、このようなＤＶＤやＢＤにおいては、映像の再生や停止を指示したり、プレーヤの各種機能を利用したり、或いはプレーヤの設定を変更したりするために、メニュー画面（或いは、ヘルプ画面）の表示が可能である。係るメニュー画面は、例えば選択可能なボタン等が表示されることにより構成される。そして、ユーザが係るボタンを選択して実行することで、例えば音声、字幕或いは視点の変更や各種設定等の対応するコマンドが実行されることとなる（特許文献１参照）。 In addition, in such a DVD or BD, a menu screen (or help screen) is used to instruct to play or stop video, to use various functions of the player, or to change player settings. Can be displayed. Such a menu screen is configured by displaying, for example, selectable buttons.

　このようなコンテンツ情報（特に、メニュー画面）は、大画面テレビでの視聴を前提として作られているのが一般的である。一方で、ポータブルＤＶＤプレーヤや車載用ナビゲーション装置等の小型テレビでの視聴も一般的になっている。この場合、画面サイズが小さいため、メニュー画面が非常に見づらくなってしまうという技術的な問題点を有している。具体的には、例えばメニュー画面に含まれる文字やアイコン等が小さいがゆえに、それらを識別することが困難になる。 Such content information (especially menu screen) is generally created on the premise of viewing on a large-screen TV. On the other hand, viewing on a small television such as a portable DVD player or an in-vehicle navigation device has become common. In this case, since the screen size is small, there is a technical problem that the menu screen becomes very difficult to see. Specifically, for example, since characters and icons included in the menu screen are small, it is difficult to identify them.
　他方で、特許文献２や特許文献３には、拡大表示例が開示されているものの、特許文献２は単に文書データを拡大表示する構成が開示されているに過ぎず、特許文献３はカメラで撮影した画像を拡大表示する構成が開示されているに過ぎない。つまり、これらの構成を採用したとしても、主映像に重ねて表示される画像情報を含むメニュー画像の見易さに寄与することはないため、依然上述の問題点は残っている。 On the other hand, although Patent Document 2 and Patent Document 3 disclose examples of enlarged display, Patent Document 2 merely discloses a configuration for enlarging and displaying document data, and Patent Document 3 is a camera. Only a configuration for enlarging and displaying a captured image is disclosed. That is, even if these configurations are adopted, the problem described above still remains because it does not contribute to the visibility of the menu image including the image information displayed to be superimposed on the main video.
　本発明は、例えば上述した従来の問題点に鑑みなされたものであり、例えば、ユーザが見やすいメニュー画像を表示することができる表示装置及び方法、並びにコンピュータプログラムを提供することを課題とする。 The present invention has been made in view of, for example, the conventional problems described above.

　以下、発明を実施するための最良の形態として、本発明の表示装置及び方法、並びにコンピュータプログラムに係る実施形態の説明を進める。 Hereinafter, as the best mode for carrying out the invention, description will be given on embodiments of the display device and method and the computer program of the present invention.
　（表示装置の実施形態）
　本発明の表示装置に係る実施形態は、複数のメニュー画像を表示画面上に表示させる表示手段と、前記表示画面上に表示される前記複数のメニュー画像の夫々を認識する認識手段と、ユーザの操作に応じて、前記認識手段により認識された前記複数のメニュー画像の選択を切り替える選択手段と、前記ユーザが選択している前記メニュー画像を拡大させて前記表示画面上に表示させるように前記表示手段を制御する制御手段とを備える。 (Embodiment of display device)
An embodiment according to the display device of the present invention includes: a display unit that displays a plurality of menu images on a display screen; a recognition unit that recognizes each of the plurality of menu images displayed on the display screen; In response to an operation, a selection unit that switches selection of the plurality of menu images recognized by the recognition unit, and the display that enlarges the menu image selected by the user and displays the menu image on the display screen. Control means for controlling the means.
　本発明の表示装置に係る実施形態によれば、表示手段の動作により、メニュー画像が表示される。本実施形態における「メニュー画像」とは、ユーザが何らかの指示を行うために表示されるメニューを示す画像を示す趣旨であって、典型的には各種コンテンツ（例えば、動画コンテンツ等）の表示動作に関する指示を行うためのメニューを示す画像である。表示動作に関する指示としては、コンテンツが表示される際の音声及び字幕の選択指示や、コンテンツの表示切替指示（例えば、通常のコンテンツの表示から、特典コンテンツの表示への切替指示）や、その他各種指示が、一例としてあげられる。通常、このようなメニュー画像は、例えばボタンやアイコンや各種文字列等を含んでいる。 According to the embodiment of the display device of the present invention, the menu image is displayed by the operation of the display means. The “menu image” in the present embodiment is intended to indicate an image indicating a menu displayed for a user to give some instruction, and typically relates to a display operation of various contents (for example, moving image contents). It is an image which shows the menu for performing an instruction | indication. Instructions related to display operations include audio and subtitle selection instructions when content is displayed, content display switching instructions (for example, switching from normal content display to privilege content display), and other various types. Instructions are given as an example. Usually, such a menu image includes, for example, buttons, icons, various character strings, and the like.
　本実施形態では特に、認識手段の動作により、表示画面上に表示される複数のメニュー画像の夫々が認識される。言い換えれば、メニュー画像が表示されているか否かが認識される。このとき、例えば複数のメニュー画像の表示位置やサイズ等が合わせて取得されるように構成してもよい。また、選択手段の動作により、例えばリモコン等を用いたユーザの操作に応じて、認識手段により認識されている複数のメニュー画像（つまり、表示画面上に表示されている複数のメニュー画像）のいずれがユーザによって選択されているかが切り替えられる。より具体的には、例えば、３つのメニュー画像が左右方向に並んで配置されていると共に真ん中に位置するメニュー画像が選択されている初期状態で、例えばユーザがリモコンの右キーを押下した場合には、選択手段の動作により、選択されているメニュー画像が真ん中に位置するメニュー画像から右端に位置するメニュー画像へと切り替えられる。この場合、選択されているメニュー画像を識別するために、例えばハイライト表示等を用いて、選択されているメニュー画像の表示態様と、選択されていないメニュー画像の表示態様とを変えるように構成してもよい。 Particularly in this embodiment, each of a plurality of menu images displayed on the display screen is recognized by the operation of the recognition means. In other words, it is recognized whether or not the menu image is displayed. At this time, for example, the display positions and sizes of a plurality of menu images may be acquired together. Further, by the operation of the selection unit, for example, any of a plurality of menu images recognized by the recognition unit (that is, a plurality of menu images displayed on the display screen) according to a user operation using a remote controller or the like. Is selected by the user. More specifically, for example, when the user presses the right key of the remote control in the initial state in which three menu images are arranged side by side and the menu image located in the middle is selected, for example. Is switched from the menu image at the center of the selected menu image to the menu image at the right end by the operation of the selection means. In this case, in order to identify the selected menu image, the display mode of the selected menu image and the display mode of the unselected menu image are changed using, for example, highlight display or the like. May be.
　その後、制御手段の動作により、ユーザが選択しているメニュー画像を拡大して表示させるように表示手段が制御される。より具体的には、ユーザが選択しているメニュー画像が、通常表示動作時における表示サイズと比較してより拡大した表示サイズを有するように表示される。 Thereafter, the display means is controlled to enlarge and display the menu image selected by the user by the operation of the control means. More specifically, the menu image selected by the user is displayed so as to have a display size that is larger than the display size during the normal display operation.
　これにより、ユーザが選択しているメニュー画像に含まれるボタンやアイコンや各種文字列等は、拡大して表示される。その結果、ユーザにとって、選択しているメニュー画像に含まれるボタンやアイコンや各種文字列等はより一層見やすくなる。従って、ユーザは、メニュー操作を誤って行うことが少なくなる又はなくなる。言い換えれば、ユーザは、メニュー操作を比較的容易に或いは確実に行うことができる。これは、相対的に小さい画面サイズを有するポータブルＤＶＤプレーヤや車載用ナビゲーション装置等における表示時に特に有効である。 Thus, the buttons, icons, various character strings, etc. included in the menu image selected by the user are enlarged and displayed. As a result, it becomes easier for the user to see buttons, icons, various character strings, and the like included in the selected menu image. Therefore, the user is less likely to perform menu operations by mistake. In other words, the user can perform the menu operation relatively easily or reliably. This is particularly effective at the time of display on a portable DVD player, an in-vehicle navigation device or the like having a relatively small screen size.
　しかも、本実施形態によれば、単に任意の表示領域を拡大表示するのではなく、メニュー画像を認識した上で該認識されたメニュー画像のうちユーザによってまさに現在選択されているメニュー画像（或いは、該メニュー画像を含む表示領域）が拡大表示される。従って、拡大表示させたい表示領域をユーザが別途指定しなくとも、通常のメニュー操作を行えば、そのメニュー操作に伴ってユーザが選択しているメニュー画像を確実に拡大表示させることができる。 In addition, according to the present embodiment, an arbitrary display area is not simply displayed in an enlarged manner, but the menu image that is currently selected by the user among the recognized menu images after recognizing the menu image (or The display area including the menu image is enlarged. Therefore, even if the user does not separately specify the display area to be enlarged, if the normal menu operation is performed, the menu image selected by the user along with the menu operation can be surely enlarged and displayed.
　本発明の表示装置に係る実施形態の一の態様では、前記認識手段は、前記メニュー画像の前記表示画面上での表示領域を認識し、前記制御手段は、前記認識手段で認識された表示領域を拡大させて前記表示画面上に表示させる。 In one aspect of the embodiment of the display device of the present invention, the recognition means recognizes a display area of the menu image on the display screen, and the control means recognizes the display area recognized by the recognition means. Is enlarged and displayed on the display screen.
　この態様によれば、認識された表示領域（つまり、メニュー画像そのものである又はメニュー画像を含む表示領域）自体が拡大されるため、上述した各種効果を好適に享受することができる。 According to this aspect, since the recognized display area (that is, the display area that is the menu image itself or includes the menu image) itself is enlarged, the above-described various effects can be suitably enjoyed.
　本発明の表示装置に係る実施形態の他の態様では、前記メニュー画像には複数の選択肢が含まれており、前記制御手段は、前記ユーザによって選択されている選択肢を含む、前記メニュー画像の一部を拡大させて前記表示画面上に表示させるように前記表示手段を制御する。 In another aspect of the embodiment of the display device of the present invention, the menu image includes a plurality of options, and the control means includes one of the menu images including the options selected by the user. The display means is controlled so as to enlarge the part and display it on the display screen.
　この態様によれば、メニュー画像中には、ユーザが選択可能な複数の選択肢（言い換えれば、選択項目）が含まれる。複数の選択肢は、例えばボタンやアイコンや文字列等の形式を有している。具体的には、例えば、メニュー画像が音声・字幕を選択するためのメニューを示すメニュー画像であれば、例えば「英語音声」を出力するために選択される選択肢や、「日本語音声」を出力するために選択される選択肢や、「英語字幕」を出力するために選択される選択肢や、「日本語字幕」を出力するために選択される選択肢が、複数の選択肢の一例としてあげられる。この複数の選択肢についても、認識手段の動作によりその表示位置やサイズ等が認識されるように構成してもよい。また、いずれの選択肢が選択されているかを識別するために、例えばハイライト表示等を用いて、選択されている選択肢の表示態様と、選択されていない選択肢の表示態様とを変えるように構成してもよい。 According to this aspect, the menu image includes a plurality of options (in other words, selection items) that can be selected by the user. The plurality of options have a format such as a button, an icon, or a character string. Specifically, for example, if the menu image is a menu image indicating a menu for selecting audio / subtitles, for example, an option selected to output “English audio” or “Japanese audio” is output. Examples of a plurality of options are an option selected to output, an option selected to output “English subtitles”, and an option selected to output “Japanese subtitles”. The plurality of options may also be configured such that their display positions and sizes are recognized by the operation of the recognition unit. Further, in order to identify which option is selected, the display mode of the selected option and the display mode of the unselected option are changed using, for example, a highlight display. May be.
　この場合、制御手段の動作により、ユーザによって選択されている選択肢を含むメニュー画像の少なくとも一部が拡大されて表示画面上に表示される。具体的には、例えば上述した「英語音声」を出力するために選択される選択肢が選択されている場合には、「英語音声」を出力するために選択される選択肢を含むメニュー画像の少なくとも一部が拡大されて表示画面上に表示される。このため、ユーザにとって、ユーザが選択している選択肢はより一層見やすくなる。従って、上述した効果を好適に享受することができる。 In this case, at least a part of the menu image including the option selected by the user is enlarged and displayed on the display screen by the operation of the control means. Specifically, for example, when the option selected to output “English speech” described above is selected, at least one of menu images including the option selected to output “English speech” is selected. The part is enlarged and displayed on the display screen. This makes it easier for the user to see the options selected by the user. Therefore, the above-described effects can be suitably enjoyed.
　尚、このとき、拡大前のメニュー画像の少なくとも一部が表示されている領域と、拡大後のメニュー画像の少なくとも一部が表示されている領域とが略同一の大きさとなるように、ユーザによって選択されている選択肢を含むメニュー画像の少なくとも一部が拡大表示されるように構成してもよい。言い換えれば、ユーザによって選択されている選択肢を含むメニュー画像の少なくとも一部は、拡大前のメニュー画像の少なくとも一部が表示されている表示画面上の領域の中において拡大表示されるように構成してもよい。尚、この表示態様については、後に図面を参照してより詳細に説明する（図５参照）。 It should be noted that at this time, an area where at least a part of the menu image before enlargement is displayed and an area where at least a part of the menu image after enlargement are displayed are approximately the same size by the user. You may comprise so that at least one part of the menu image containing the selected choice may be expanded and displayed. In other words, at least a part of the menu image including the option selected by the user is configured to be enlarged and displayed in an area on the display screen where at least a part of the menu image before the enlargement is displayed. May be. This display mode will be described later in detail with reference to the drawings (see FIG. 5).
　本発明の表示装置に係る実施形態の他の態様では、前記制御手段は、前記ユーザに選択されている前記メニュー画像の全体を拡大させて前記表示画面上に表示させるように前記表示手段を制御する。 In another aspect of the embodiment of the display device according to the present invention, the control means controls the display means so that the entire menu image selected by the user is enlarged and displayed on the display screen. To do.
　この態様によれば、ユーザが選択しているメニュー画像が拡大された上で（言い換えれば、引き伸ばされた上で）、表示画面全体に表示される。このため、ユーザにとって、ユーザが選択している選択肢はより一層見やすくなる。従って、上述した効果を好適に享受することができる。尚、この表示態様については、後に図面を参照してより詳細に説明する（図４参照）。 According to this aspect, the menu image selected by the user is enlarged (in other words, enlarged) and displayed on the entire display screen. This makes it easier for the user to see the options selected by the user. Therefore, the above-described effects can be suitably enjoyed. This display mode will be described later in detail with reference to the drawings (see FIG. 4).
　本発明の表示装置に係る実施形態の他の態様では、前記制御手段は、前記ユーザによって選択されている選択肢を中心とした前記メニュー画像の一部を拡大して表示させるように前記表示手段を制御する。 In another aspect of the embodiment of the display device according to the present invention, the control means causes the display means to enlarge and display a part of the menu image centered on the option selected by the user. Control.
　この態様によれば、ユーザが選択している選択肢を中心としたメニュー画像の一部が拡大して表示されるため、ユーザは、選択している選択肢のみならずその周辺に位置する選択肢をも認識することができる。このため、ユーザは、次にどのような操作を行うことでどの選択肢が選択されるかを認識することができる。従って、ユーザは、次にどのような操作を行えばよいかを認識することができる。 According to this aspect, since a part of the menu image centered on the option selected by the user is enlarged and displayed, the user has not only the selected option but also the options located in the vicinity thereof. Can be recognized. For this reason, the user can recognize which option is selected by performing what operation next. Therefore, the user can recognize what operation should be performed next.
　本発明の表示装置に係る実施形態の他の態様では、前記ユーザに選択されている前記メニュー画像の形状に応じて、拡大させる領域の形状を変化させるように前記表示手段を制御する。 In another aspect of the embodiment of the display device of the present invention, the display means is controlled to change the shape of the area to be enlarged according to the shape of the menu image selected by the user.
　この態様によれば、選択されているメニュー画像の形状に応じて、拡大表示を行う表示画面上の領域の形状が変化させられる。典型的には、メニュー画像の形状と拡大表示を行う表示画面上の領域の形状とが相似の関係となる或いは類似の関係となるように、拡大表示を行う表示画面上の領域の形状が変化させられる。これにより、より一層見やすい態様で拡大表示を行うことができる。 According to this aspect, the shape of the area on the display screen to be enlarged is changed according to the shape of the selected menu image. Typically, the shape of the area on the display screen for enlarged display changes so that the shape of the menu image and the shape of the area on the display screen for enlarged display are similar or similar. Be made. Thereby, an enlarged display can be performed in a more easily viewable manner.
　本発明の表示装置に係る実施形態の他の態様では、前記メニュー画像は背景に重ねて表示されており、前記制御手段は、前記メニュー画像と共に前記背景の一部を拡大させて表示させるように前記表示手段を制御する。 In another aspect of the embodiment of the display device according to the present invention, the menu image is displayed so as to be superimposed on a background, and the control unit displays a part of the background in an enlarged manner together with the menu image. The display means is controlled.
　この態様によれば、メニュー画像は、ブルーバック画面や映画等のコンテンツを示す画像（或いは、動画像）等が一例となる背景に重ねて表示される。この場合には、メニュー画像のみならず、背景の一部（例えば、拡大表示させるメニュー画像が重ねられている一部の背景）も拡大して表示される。これにより、背景が表示される場合であっても、上述した効果を享受することができる。 According to this aspect, the menu image is displayed in such a manner that an image (or a moving image) showing content such as a blue back screen or a movie is superimposed on the background as an example. In this case, not only the menu image but also a part of the background (for example, a part of the background on which the menu image to be enlarged is overlaid) is enlarged and displayed. Thereby, even if a background is displayed, the effect mentioned above can be enjoyed.
　本発明の表示装置に係る実施形態の他の態様では、前記表示画面の大きさを取得する画面サイズ取得手段を有し、前記制御手段は、取得した前記表示画面の大きさに応じて、拡大させて表示させる前記メニュー画像の拡大率を変化させるように前記表示手段を制御する。 In another aspect of the embodiment of the display device of the present invention, the display device includes a screen size acquisition unit that acquires the size of the display screen, and the control unit expands according to the acquired size of the display screen. The display means is controlled to change the enlargement ratio of the menu image to be displayed.
　この態様によれば、表示画面のサイズに応じて、メニュー画像を拡大表示する際の拡大率を適宜変化させることができる。具体的には、例えば、表示画面のサイズが相対的に大きければ、メニュー画像をそれほど拡大させる必要はないため、拡大率を相対的に小さくする一方で、表示画面のサイズが相対的に小さければ、メニュー画像を拡大させる必要性が高いため、拡大率を相対的に大きくするように構成してもよい。これにより、より一層見やすい態様で拡大表示を行うことができる。 According to this aspect, the enlargement ratio when the menu image is enlarged and displayed can be appropriately changed according to the size of the display screen. Specifically, for example, if the size of the display screen is relatively large, there is no need to enlarge the menu image so much, so the enlargement ratio is relatively small, while the size of the display screen is relatively small. Since the necessity of enlarging the menu image is high, the enlargement ratio may be relatively increased. Thereby, an enlarged display can be performed in a more easily viewable manner.

　以下、本発明の実施例を、図面に基づいて説明する。 Hereinafter, embodiments of the present invention will be described with reference to the drawings.
　（１）基本構成
　始めに、図１を参照して、本発明の表示装置に係る実施例の基本構成について説明する。尚、以下の説明では、本発明の表示装置を、車載型のナビゲーション装置に搭載されるＤＶＤプレーヤやＢＤプレーヤ等の再生装置に適用した例について説明する。ここに、図１は、本実施例に係る再生装置の基本構成を概念的に示すフローチャートである。 (1) Basic Configuration First, the basic configuration of an embodiment according to the display device of the present invention will be described with reference to FIG. In the following description, an example in which the display device of the present invention is applied to a playback device such as a DVD player or a BD player mounted on an in-vehicle navigation device will be described. FIG. 1 is a flowchart conceptually showing the basic structure of the reproducing apparatus in the example.
　図１に示すように、再生装置１は、ディスクドライブ１００と、バックエンド２００と、スピーカ３０１と、ディスプレイ３０２とを備える。 As shown in FIG. 1, the playback apparatus 1 includes a disk drive 100, a back end 200, a speaker 301, and a display 302.
　ディスクドライブ１００は、光ディスク１０１と、光ピックアップ１０２と、ドライブ制御回路１０３と、ＡＴＡＰＩインターフェース（Ｉ／Ｆ）１０４とを備える。 The disk drive 100 includes an optical disk 101, an optical pickup 102, a drive control circuit 103, and an ATAPI interface (I / F) 104.
　光ディスク１０１には、例えば映画等のタイトルの動画像（例えば、ＭＰＥＧ動画）を示す主映像データと、映画等のタイトルの音声を示す音声データと、タイトルの再生に関する指示・操作を行うために表示されるメニュー画面を示すグラフィックデータとが多重化されて記録されている。 On the optical disk 101, for example, main video data indicating a moving image of a title such as a movie (for example, MPEG moving image), audio data indicating a sound of a title such as a movie, and a display for instructing and operating the title are displayed. Graphic data indicating the menu screen to be displayed is multiplexed and recorded.
　ディスクドライブ１００においては、不図示のスピンドルモータにより光ディスク１０１が回転させられながら、光ピックアップ１０２よりレーザ光が光ディスク１０１に対して照射される。照射されたレーザ光は、光ディスク１０１において反射される。反射光は、光ピックアップ１０２内のフォトディテクタにより受光される。これにより、光ディスク１０１に記録されたデータ（つまり、多重化された主映像データ、音声データ及びグラフィックデータ）を読み取ることができる。これらの動作の制御は、ドライブ制御回路１０３の動作により行われる。尚、読み取られたデータは、制御回路１０３の制御の下、ＡＴＡＰＩ　Ｉ／Ｆ１０４を介してバックエンド２００へと出力される。 In the disk drive 100, the optical disk 101 is irradiated with laser light from the optical pickup 102 while the optical disk 101 is rotated by a spindle motor (not shown). The irradiated laser light is reflected on the optical disc 101. The reflected light is received by the photodetector in the optical pickup 102. Thereby, the data recorded on the optical disc 101 (that is, multiplexed main video data, audio data, and graphic data) can be read. These operations are controlled by the operation of the drive control circuit 103. The read data is output to the back end 200 via the ATAPI I / F 104 under the control of the control circuit 103.
　バックエンド２００は、ＡＴＡＰＩ　Ｉ／Ｆ２０１と、デマルチプレクサ２０２と、ＭＰＥＧデコーダ２１０と、グラフィックデコーダ２１１と、ビデオミキサー２１２と、プレーヤＯＳＤ２１４と、リサイザ２１５と、ビデオミキサー２１６と、音声デコーダ２２０とを備えている。 The back end 200 includes an ATAPI I / F 201, a demultiplexer 202, an MPEG decoder 210, a graphic decoder 211, a video mixer 212, a player OSD 214, a resizer 215, a video mixer 216, and an audio decoder 220. ing.
　ＡＴＡＰＩ　Ｉ／Ｆ２０１を介してディスクドライブ１００より入力されるデータは、デマルチプレクサ２０２により、主映像データと、音声データと、グラフィックデータとに分離される。その後、主映像データは、ＭＰＥＧデコーダ２１０においてデコードされ、音声データは、音声デコーダ２２０においてデコードされ、グラフィックデータは、グラフィックデコーダ２１１においてデコードされる。 Data input from the disk drive 100 via the ATAPI I / F 201 is separated into main video data, audio data, and graphic data by the demultiplexer 202. Thereafter, the main video data is decoded by the MPEG decoder 210, the audio data is decoded by the audio decoder 220, and the graphic data is decoded by the graphic decoder 211.
　デコードされた主映像データとデコードされたグラフィックデータとは、ビデオミキサー２１２においてミキシングされる。その結果、映像データが生成される。また、映像データには、必要に応じて、ビデオミキサー２１６において、プレーヤＯＳＤ２１４より出力されるＯＳＤ画像が重畳される。その後、映像データは、ディスプレイ３０２に出力される。その結果、ディスプレイ３０２には、映像データが示す映像が表示される。また、デコードされた音声データは、スピーカ３０１に出力される。その結果、スピーカ３０１からは、音声データが示す音声が出力される。 The decoded main video data and the decoded graphic data are mixed in the video mixer 212. As a result, video data is generated. In addition, the OSD image output from the player OSD 214 is superimposed on the video data in the video mixer 216 as necessary. Thereafter, the video data is output to the display 302. As a result, the video indicated by the video data is displayed on the display 302. The decoded audio data is output to the speaker 301. As a result, the sound indicated by the sound data is output from the speaker 301.
　本実施例では特に、デコードされた主映像データとデコードされたグラフィックデータとがビデオミキサー２１２においてミキシングされることで生成される映像データを用いて、リサイザ２１５の動作による拡大表示が適宜行われる。この拡大表示動作については、後に詳述するため（図２から図５参照）、ここでの詳細な説明については省略する。 In this embodiment, in particular, enlarged display by the operation of the resizer 215 is appropriately performed using video data generated by mixing the decoded main video data and the decoded graphic data in the video mixer 212. Since this enlarged display operation will be described in detail later (see FIGS. 2 to 5), a detailed description thereof will be omitted.
　尚、上述した各種構成要素は、ＣＰＵ２３０の制御の下に動作するように構成されている。また、ＣＰＵ２３０が動作するためのプログラム（例えば、ファームウェア等）は、メモリ２３１に格納されている。また、メモリ２３１は、再生装置１におけるデータ処理全般に用いられるＲＡＭ領域としても機能する。 Note that the various components described above are configured to operate under the control of the CPU 230. A program (for example, firmware) for operating the CPU 230 is stored in the memory 231. Further, the memory 231 also functions as a RAM area used for data processing in the playback apparatus 1 in general.
　（２）動作原理
　続いて、図２を参照して、本実施例に係る再生装置１の動作の流れについて説明する。ここに、図２は、本実施例に係る再生装置１の動作の流れを概念的に示すフローチャートである。 (2) Operation Principle Next, with reference to FIG. 2, an operation flow of the reproducing apparatus 1 according to the present embodiment will be described. FIG. 2 is a flowchart conceptually showing a flow of operations of the reproducing apparatus 1 in the example.
　図２に示すように、光ディスク１０１に記録されたデータの再生が開始される（ステップＳ１０１）。 As shown in FIG. 2, reproduction of data recorded on the optical disc 101 is started (step S101).
　この再生動作中には、一又は複数のメニュー画像が表示されるか否かが適宜判定される（ステップＳ１０２）。例えば、リモコン等を用いてユーザがメニュー画像の表示を指示した場合には、メニュー画像が表示されると判定される。 During this reproduction operation, it is determined as appropriate whether or not one or more menu images are displayed (step S102). For example, when the user instructs display of a menu image using a remote controller or the like, it is determined that the menu image is displayed.
　ステップＳ１０２における判定の結果、メニュー画像が表示されないと判定された場合には（ステップＳ１０２：Ｎｏ）、通常の再生動作（つまり、主映像データを含む映像データの再生動作や音声データの再生動作）が継続して行われる（ステップＳ１１４）。 As a result of the determination in step S102, if it is determined that the menu image is not displayed (step S102: No), normal playback operation (that is, playback operation of video data including main video data and playback operation of audio data). Is continuously performed (step S114).
　その後、再生動作を終了するか否かが判定される（ステップＳ１１５）。例えば、光ディスク１０１に記録されたデータの全ての再生が終了した場合や、リモコン等を用いてユーザが再生の終了を指示した場合には、再生動作を終了すると判定される。 Thereafter, it is determined whether or not to end the reproduction operation (step S115). For example, when all of the data recorded on the optical disc 101 has been reproduced, or when the user instructs the end of reproduction using a remote controller or the like, it is determined that the reproduction operation is to be terminated.
　ステップＳ１１５における判定の結果、再生動作を終了すると判定された場合には（ステップＳ１１５：Ｙｅｓ）、再生動作を終了する。他方で、ステップＳ１１５における判定の結果、再生動作を終了しないと判定された場合には（ステップＳ１１５：Ｎｏ）、ステップＳ１０２へ戻り、ステップＳ１０２以降の動作が繰り返される。 If the result of determination in step S115 is that the playback operation is to be terminated (step S115: Yes), the playback operation is terminated. On the other hand, as a result of the determination in step S115, when it is determined not to end the reproduction operation (step S115: No), the process returns to step S102, and the operations after step S102 are repeated.
　他方、ステップＳ１０２における判定の結果、メニュー画像が表示されると判定された場合には（ステップＳ１０２：Ｙｅｓ）、続いて、メニュー画像を表示するための前処理が行われる（ステップＳ１０３）。この前処理としては、グラフィックデコーダ２１１におけるグラフィックデータのデコード処理が一例としてあげられる。 On the other hand, when it is determined that the menu image is displayed as a result of the determination in step S102 (step S102: Yes), preprocessing for displaying the menu image is subsequently performed (step S103). As an example of this pre-processing, a graphic data decoding process in the graphic decoder 211 can be given.
　また、デコード処理に続いて又は並行して、グラフィックデータが示す一又は複数のメニュー画面の夫々の表示位置や、表示サイズや、表示形状等が合わせて認識される。これにより、再生装置１は、ディスプレイ３０２の表示画面のいずれの箇所にメニュー画像が表示されているかを確実に認識することができ、その結果、メニュー画像の背景として表示される主映像とメニュー画像とを区別して認識することができる。尚、本実施形態においては、メニュー画面の夫々の表示位置や、表示サイズや、表示形状等を示す情報は、グラフィックデータ中に含まれていることが好ましい。このため、グラフィックデータをデコード処理することで、これらの情報を比較的容易に認識することができる。 Also, following or in parallel with the decoding process, the display position, display size, display shape, etc. of one or more menu screens indicated by the graphic data are recognized together. Thereby, the playback device 1 can surely recognize in which part of the display screen of the display 302 the menu image is displayed, and as a result, the main video and the menu image displayed as the background of the menu image. And can be recognized separately. In the present embodiment, it is preferable that information indicating each display position, display size, display shape, etc. of the menu screen is included in the graphic data. Therefore, it is possible to recognize these pieces of information relatively easily by decoding the graphic data.
　続いて、一又は複数のメニュー画像上においてデフォールトで選択されている項目（言い換えれば、ボタンやアイコン等のメニュー選択肢画像）が取得される（ステップＳ１０４）。具体的には、一又は複数のメニュー画像を表示した場合にデフォールトで選択されている（つまり、デフォールトでフォーカスされている）メニュー選択肢画像の位置情報（例えば、表示位置座標）が取得される。加えて、拡大して表示させるべき拡大表示領域のサイズ情報及び位置情報が算出される（ステップＳ１０５）。ここでは、例えば、ユーザにより選択されている（或いは、デフォールトで選択されている）メニュー選択肢画像が属するメニュー画像の少なくとも一部を含む矩形の表示領域が、拡大表示領域として算出される。尚、選択されているメニュー画像やメニュー選択肢画像の表示位置は、ステップＳ１０３やＳ１０４において認識済みであるため、認識された表示位置を参照することで、拡大表示領域は容易に算出される。 Subsequently, an item selected by default on one or a plurality of menu images (in other words, menu option images such as buttons and icons) is acquired (step S104). Specifically, position information (for example, display position coordinates) of a menu option image that is selected by default when one or a plurality of menu images are displayed (that is, focused by default) is acquired. In addition, size information and position information of the enlarged display area to be enlarged and displayed are calculated (step S105). Here, for example, a rectangular display area including at least a part of the menu image to which the menu option image selected by the user (or selected by default) belongs is calculated as the enlarged display area. Since the display position of the selected menu image or menu option image has already been recognized in steps S103 and S104, the enlarged display area can be easily calculated by referring to the recognized display position.
　その後、拡大表示領域の拡大表示が行われる（ステップＳ１０６）。具体的には、拡大表示領域に含まれるメニュー画像及び主映像の一部を含む映像データに対して、リサイザ２１５により、メニュー画像及び主映像の一部を任意の倍率で拡大表示させるための拡大表示処理が施される。その結果、ディスプレイ３０２には、拡大表示領域に含まれるメニュー画像及び主映像の一部が任意の倍率で拡大表示される。この拡大表示の態様については、後に詳述する。 Thereafter, the enlarged display area is enlarged and displayed (step S106). Specifically, the resizer 215 enlarges the menu image and part of the main video to be enlarged and displayed at an arbitrary magnification with respect to the video data including the menu image and part of the main video included in the enlarged display area. Display processing is performed. As a result, on the display 302, the menu image and part of the main video included in the enlarged display area are enlarged and displayed at an arbitrary magnification. This enlarged display mode will be described in detail later.
　続いて、選択されているメニュー画像（或いは、メニュー選択肢画像）が変化したか否かが判定される（ステップＳ１０７）。例えば、ユーザがリモコンの上キーや下キーや右キーや左キーや数字キーを押下することによって、選択されているメニュー画像が変化した場合には、選択されているメニュー画像が変化したと判定される。より具体的には、例えば、字幕選択メニュー選択肢画像が選択されていた状態から、音声選択メニュー選択肢画像が選択されている状態に変化した場合には、選択されているメニュー選択肢画像が変化したと判定される。同様に、例えば、音声字幕選択メニュー画像中に含まれているメニュー選択肢画像が選択されていた状態から、チャプター選択メニュー画像中に含まれているメニュー選択肢画像が選択されている状態に変化した場合には、選択されているメニュー画像及びメニュー選択肢画像が変化したと判定される。 Subsequently, it is determined whether or not the selected menu image (or menu option image) has changed (step S107). For example, if the selected menu image changes when the user presses the up key, down key, right key, left key, or numeric key on the remote control, it is determined that the selected menu image has changed. Is done. More specifically, for example, when the subtitle selection menu option image is changed to the state where the audio selection menu option image is selected, the selected menu option image is changed. Determined. Similarly, for example, when the menu option image included in the audio subtitle selection menu image is changed to the state where the menu option image included in the chapter selection menu image is selected It is determined that the selected menu image and menu option image have changed.
　ステップＳ１０７における判定の結果、現在選択されているメニュー画像或いはメニュー選択肢画像が変化したと判定された場合には（ステップＳ１０７：Ｙｅｓ）、変化後に選択されているメニュー画像或いは、メニュー選択肢画像（つまり、新たに選択されたメニュー画像或いは、メニュー選択肢画像）の位置情報が取得される（ステップＳ１１３）。その後、改めて、変化後に選択されているメニュー画像或いは、メニュー選択肢画像（つまり、新たに選択されたメニュー画像或いは、メニュー選択肢画像）の少なくとも一部を含む矩形の表示領域が、新たな拡大表示領域として算出される（ステップＳ１０５）。以降、ステップＳ１０５以降の動作が繰り返される。 As a result of the determination in step S107, if it is determined that the currently selected menu image or menu option image has changed (step S107: Yes), the menu image or menu option image selected after the change (that is, the menu option image) The position information of the newly selected menu image or menu option image) is acquired (step S113). Thereafter, a rectangular display area including at least a part of the menu image or menu option image (that is, the newly selected menu image or menu option image) selected after the change is newly displayed as a new enlarged display area. (Step S105). Thereafter, the operations after step S105 are repeated.
　他方、ステップＳ１０７における判定の結果、選択されているメニュー画像或いは、メニュー選択肢画像が変化していないと判定された場合には（ステップＳ１０７：Ｎｏ）、続いて、現在選択されているメニュー選択肢画像（つまり、項目）に対して決定指示がなされたか否かが判定される（ステップＳ１０８）。例えば、ユーザがリモコンの決定キー等を押下することによって、選択されているメニュー選択肢画像が特定している動作の実行を指示した場合には、選択されているメニュー選択肢画像に対して決定指示がなされたと判定される。 On the other hand, as a result of the determination in step S107, if it is determined that the selected menu image or menu option image has not changed (step S107: No), then the currently selected menu option image It is determined whether or not a decision instruction has been issued for (item) (step S108). For example, when the user instructs execution of the operation specified by the selected menu option image by pressing a determination key or the like on the remote controller, a determination instruction is given to the selected menu option image. It is determined that it was made.
　ステップＳ１０８における判定の結果、選択されているメニュー選択肢画像に対して決定指示がなされていないと判定された場合には（ステップＳ１０８：Ｎｏ）、続いて、タイムアウトであるか否かが判定される（ステップＳ１０９）。つまり、所定の時間が経過したか否かが判定される。 As a result of the determination in step S108, if it is determined that a determination instruction has not been issued for the selected menu option image (step S108: No), it is subsequently determined whether or not a timeout has occurred. (Step S109). That is, it is determined whether or not a predetermined time has elapsed.
　ステップＳ１０９における判定の結果、タイムアウトでないと判定された場合には（ステップＳ１０９：Ｎｏ）、ステップＳ１０７へ戻り、ステップＳ１０７以降の動作が繰り返される。 If the result of determination in step S109 is that there is no timeout (step S109: No), the process returns to step S107, and the operations after step S107 are repeated.
　他方、ステップＳ１０９における判定の結果、タイムアウトであると判定された場合には（ステップＳ１０９：Ｙｅｓ）、ステップＳ１１０へ進む。 On the other hand, if it is determined as a timeout as a result of the determination in step S109 (step S109: Yes), the process proceeds to step S110.
　他方、ステップＳ１０８における判定の結果、選択されているメニュー選択肢画像に対して決定指示がなされていないと判定された場合には（ステップＳ１０８：Ｎｏ）、続いて、その決定指示が、一又は複数のメニュー画像を含むメニュー画面全体の表示切替指示であるか否かが判定される（ステップＳ１１０）。具体的には、例えば、音声選択を行うための音声選択メニュー画像を開くために選択・決定されるメニュー画像と字幕選択を行うための字幕選択メニュー画像を開くために選択・決定されるメニュー画像とを含むメインメニュー画面が表示されている状態で、音声選択メニュー画像を開くためのメニュー画像が選択・決定された場合には、メインメニュー画面から音声選択メニュー画像（例えば、英語音声及び日本語音声のいずれかを選択するメニュー画像）を含むメニュー画面への表示切替動作が行われる必要がある。従って、このような場合は、メニュー画面全体の表示切替指示が行われたと判定される。 On the other hand, as a result of the determination in step S108, when it is determined that the determination instruction has not been issued for the selected menu option image (step S108: No), then the determination instruction is one or more. It is determined whether or not it is a display switching instruction for the entire menu screen including the menu image (step S110). Specifically, for example, a menu image selected / determined to open a voice selection menu image for performing voice selection and a menu image selected / determined to open a subtitle selection menu image for performing subtitle selection When a menu image for opening a voice selection menu image is selected and determined while a main menu screen including is displayed, a voice selection menu image (for example, English voice and Japanese) is selected from the main menu screen. It is necessary to perform a display switching operation to a menu screen including a menu image for selecting one of sounds. Therefore, in such a case, it is determined that a display switching instruction for the entire menu screen has been issued.
　ステップＳ１１０における判定の結果、決定指示がメニュー画面全体の表示切替指示であると判定された場合には（ステップＳ１１０：Ｙｅｓ）、メニュー画面全体の表示切替動作を行った後、ステップ１０４へ戻り、表示切替後の新たなメニュー画面に含まれる一又は複数のメニュー画像に対して、ステップＳ１０４以降の動作が行われる。 As a result of the determination in step S110, when it is determined that the determination instruction is a display switching instruction for the entire menu screen (step S110: Yes), the display switching operation for the entire menu screen is performed, and then the process returns to step 104. The operation after step S104 is performed on one or a plurality of menu images included in the new menu screen after the display switching.
　他方、ステップＳ１１０における判定の結果、決定指示がメニュー画面全体の表示切替指示でないと判定された場合には（ステップＳ１１０：Ｎｏ）、続いて、選択・決定された動作（つまり、メニュー画面全体の表示切替動作以外の動作）が行われる（ステップＳ１１１）。 On the other hand, as a result of the determination in step S110, if it is determined that the determination instruction is not a display switching instruction for the entire menu screen (step S110: No), subsequently, the selected / determined operation (that is, the entire menu screen) Operation other than the display switching operation) is performed (step S111).
　続いて、通常の再生動作へ戻るか否かが判定される（ステップＳ１１２）。具体的には、メニュー画面の表示動作を終了するか否かが判定される。 Subsequently, it is determined whether or not to return to the normal reproduction operation (step S112). Specifically, it is determined whether or not to end the menu screen display operation.
　ステップＳ１１２における判定の結果、通常の再生動作へ戻らない（つまり、メニュー画面の表示を継続する）と判定された場合には（ステップＳ１１２：Ｎｏ）、ステップＳ１１０へ戻り、ステップＳ１１０以降の動作が繰り返される。 As a result of the determination in step S112, if it is determined not to return to the normal reproduction operation (that is, display of the menu screen is continued) (step S112: No), the process returns to step S110, and the operations after step S110 are performed. Repeated.
　他方、ステップＳ１１２における判定の結果、通常の再生動作へ戻る（つまり、メニュー画面の表示を終了する）と判定された場合には（ステップＳ１１２：Ｙｅｓ）、ステップＳ１１４以降の動作が行われる。 On the other hand, as a result of the determination in step S112, when it is determined that the normal playback operation is to be returned (that is, the display of the menu screen is terminated) (step S112: Yes), the operations after step S114 are performed.
　続いて、図３及び図４を参照して、具体的なメニュー画像の表示の態様について説明を進める。ここに、図３は、拡大表示を行う前のメニュー画像の表示の態様を概念的に示す平面図であり、図４は、拡大表示を行った後のメニュー画像の表示の態様を概念的に示す平面図である。 Subsequently, with reference to FIG. 3 and FIG. 4, a specific menu image display mode will be described. FIG. 3 is a plan view conceptually showing a display mode of the menu image before the enlarged display, and FIG. 4 conceptually shows a display mode of the menu image after the enlarged display. FIG.
　図３（ａ）においては、映画等の主映像に重ねて、ボタンやウインドウ等のメニュー選択肢画像を含むメニュー画像が表示される例を示している。具体的には、図３（ａ）に示す例では、ディスプレイ３０１の表示画面の左上から順に、映画等の主映像の再生を開始するために選択・決定される「本編スタート用メニュー画像」と、音声や字幕を選択するために選択・決定される「音声・字幕用メニュー画像」と、所望のチャプターからの再生を行うために選択・決定される「チャプター用メニュー画像」と、特典メニュー用のメニュー画像を開くために選択・決定される「特典メニュー用メニュー画像」と、予告編の再生を開始するために選択・決定される「予告編集用メニュー画像」とが、主映像に重ねて表示されている。 FIG. 3A shows an example in which a menu image including menu option images such as buttons and windows is displayed over a main video such as a movie. Specifically, in the example illustrated in FIG. 3A, “main image start menu image” selected and determined in order to start playback of a main video such as a movie in order from the upper left of the display screen of the display 301. , “Sound / Subtitle Menu Image” to be selected / decided for selecting audio and subtitles, “Chapter Menu Image” to be selected / decided for playback from the desired chapter, and privilege menu The menu image for the special menu that is selected / decided to open the menu image and the menu image for the preview editing that is selected / decided to start playback of the trailer are displayed over the main video. Has been.
　また、図３（ａ）においては、「音声・字幕用メニュー画像」がハイライト表示されている。このハイライト表示は、現在選択されているメニュー画像を示すための表示である。従って、図３（ａ）においては、「音声・字幕用メニュー画像」が選択されている状態が示されている。この場合、音声・字幕を選択するためのメニュー選択肢画像（例えば、ボタン）を構成する「日本語５．１ｃｈボタン」と「英語５．１ｃｈボタン」と「日本語解説２ｃｈボタン」とが更に表示されている。ここでは、３つのメニュー選択肢画像のうち「英語５．１ｃｈボタン」がハイライト表示されている。つまり、図３（ａ）においては、「英語５．１ｃｈボタン」が選択されている状態が示されている。 In FIG. 3A, “menu image for audio / subtitles” is highlighted. This highlight display is a display for showing the currently selected menu image. Accordingly, FIG. 3A shows a state where “menu image for audio / subtitles” is selected. In this case, “Japanese 5.1ch button”, “English 5.1ch button”, and “Japanese commentary 2ch button” constituting a menu option image (for example, button) for selecting audio / subtitles are further displayed. Has been. Here, “English 5.1ch button” among the three menu option images is highlighted. That is, FIG. 3A shows a state where the “English 5.1ch button” is selected.
　ここで、図３（ａ）に示す状態のメニュー画像に対して拡大表示が行われると、図４（ａ）に示すように、「音声・字幕用メニュー画像」及びその周辺領域を含む拡大表示領域が、ディスプレイ３０２の表示画面全体に拡大表示される。ここでは、周辺領域として、「音声・字幕用メニュー画像」の左側に表示される「本編スタート用メニュー画像」や、「音声・字幕用メニュー画像」の右側に表示される「チャプター用メニュー画像」が含まれている例を示している。 Here, when an enlarged display is performed on the menu image in the state shown in FIG. 3A, as shown in FIG. 4A, an enlarged display including the “audio / subtitle menu image” and its peripheral area is displayed. The area is enlarged and displayed on the entire display screen of the display 302. Here, as the peripheral area, the “main menu start menu image” displayed on the left side of the “audio / subtitle menu image” and the “chapter menu image” displayed on the right side of the “audio / subtitle menu image”. An example is included.
　また、図３（ａ）に示す状態において、ユーザがリモコンの右キーを押せば、図３（ｂ）に示す状態に移動する。つまり、「音声・字幕用メニュー画像」が選択されている状態から、「音声・字幕用メニュー画像」の右側に表示されている「チャプター用メニュー画像」が選択されている状態へと表示態様が切り替わる。加えて、音声・字幕を選択するためのメニュー選択肢画像の表示が終了すると共にチャプターを選択するためのメニュー選択肢画像を構成する９個の「数字ボタン」が表示される。但し、本実施例においては拡大表示が行われるため、実際には、図４（ｂ）に示す状態へと表示態様が切り替わる。具体的には、図４（ｂ）に示すように、「チャプター用メニュー画像」及びその周辺領域を含む拡大表示領域が、ディスプレイ３０２の表示画面全体に拡大表示される。ここでは、周辺領域として、「チャプター用メニュー画像」の左側に表示される「音声・字幕用メニュー画像」や、「チャプター用メニュー画像」の右側に表示される「特典メニュー用メニュー画像」が含まれている例を示している。 In the state shown in FIG. 3A, if the user presses the right key on the remote controller, the state moves to the state shown in FIG. In other words, the display mode changes from the state where “sound / subtitle menu image” is selected to the state where “chapter menu image” displayed on the right side of “sound / subtitle menu image” is selected. Switch. In addition, the display of the menu option images for selecting audio / subtitles is finished, and nine “number buttons” constituting the menu option images for selecting chapters are displayed. However, since the enlarged display is performed in the present embodiment, the display mode is actually switched to the state shown in FIG. Specifically, as shown in FIG. 4B, an enlarged display area including the “chapter menu image” and its peripheral area is enlarged and displayed on the entire display screen of the display 302. Here, the peripheral area includes “sound / subtitle menu image” displayed on the left side of “chapter menu image” and “privilege menu image” displayed on the right side of “chapter menu image”. An example is shown.
　このように、本実施例に係る再生装置１によれば、現在選択されているメニュー画像が拡大して表示される。その結果、ユーザにとって、現在選択されているメニュー画像を構成するボタンやアイコンや各種文字列等はより一層見やすくなる。これは、相対的に小さい画面サイズ（典型的には、例えば１０型以下の画面サイズ）を有するポータブルＤＶＤプレーヤや車載用ナビゲーション装置等における表示時に特に有効である。 Thus, according to the playback apparatus 1 according to the present embodiment, the currently selected menu image is enlarged and displayed. As a result, it becomes easier for the user to see buttons, icons, various character strings, and the like constituting the currently selected menu image. This is particularly effective at the time of display on a portable DVD player, an in-vehicle navigation device or the like having a relatively small screen size (typically, for example, a screen size of 10 type or less).
　特に、本実施例によれば、ディスプレイ３０２上の表示画面上の任意の領域を拡大表示するのではなく、一又は複数のメニュー画像をいわば自動的に認識した上で、該認識されたメニュー画像のうちユーザによってまさに現在選択されているメニュー画像が拡大表示される。従って、ユーザが通常のメニュー操作を行えば、そのメニュー操作に伴ってユーザが選択しているメニュー画像を確実に拡大表示させることができる。言い換えれば、ユーザがメニュー操作とは別個独立の操作として拡大表示させたい表示領域を別途指定しなくとも、ユーザが選択しているメニュー画像を確実に拡大表示させることができる。これにより、ユーザの操作負荷を上げることなく、ユーザが選択しているメニュー画像を確実に拡大表示させることができる。 In particular, according to the present embodiment, an arbitrary area on the display screen on the display 302 is not enlarged, but one or a plurality of menu images are automatically recognized, and the recognized menu image is recognized. The menu image currently selected by the user is enlarged and displayed. Therefore, if the user performs a normal menu operation, the menu image selected by the user along with the menu operation can be surely enlarged and displayed. In other words, the menu image selected by the user can be surely enlarged and displayed without the user separately designating a display area to be enlarged and displayed as an operation independent of the menu operation. As a result, the menu image selected by the user can be reliably enlarged and displayed without increasing the operation load on the user.
　また、本実施例においては、拡大表示された後であっても、現在選択されているメニュー画像のみならず、現在選択されているメニュー画像に隣接するメニュー画像も合わせて表示される。このため、ユーザは、自身が現在選択しているメニュー画像のみならず、現在表示されているメニュー画面の全体構成（或いは、その一部）をも概観することができる。具体的には、右キーの押下や左キーの押下等を含むリモコン操作によって、メニュー画面の状態がどのように切り替わるかを容易に認識することができる。このため、ユーザは、次にどのような操作を行うのが好ましいかという判断を比較的容易に行うことができる。 In this embodiment, not only the currently selected menu image but also the menu image adjacent to the currently selected menu image is displayed together even after the enlarged display. Therefore, the user can overview not only the menu image currently selected by the user but also the entire configuration (or part thereof) of the currently displayed menu screen. Specifically, it is possible to easily recognize how the state of the menu screen is switched by a remote control operation including pressing of the right key and pressing of the left key. Therefore, the user can relatively easily determine what operation should be performed next.
　この意味において、拡大表示領域には、少なくとも現在選択されているメニュー画像に隣接するメニュー画像を含むように構成することが好ましい。但し、現在選択されているメニュー画像の見易さという観点からは、拡大表示領域には、現在選択されているメニュー画像を含んでいれば良く、現在選択されているメニュー画像に隣接するメニュー画像を含んでいなくともよい。 In this sense, it is preferable that the enlarged display area includes at least a menu image adjacent to the currently selected menu image. However, from the viewpoint of easy viewing of the currently selected menu image, the enlarged display area only needs to include the currently selected menu image, and the menu image adjacent to the currently selected menu image. May not be included.
　尚、図４に示す例では、拡大表示領域をディスプレイ３０２の表示画面全体に拡大して表示する例について説明している。しかしながら、拡大表示領域中で拡大表示を完結させる一方で、拡大表示領域以外の領域では通常の表示を行うように構成してもよい。この表示例について、図５を参照しながら説明する。ここに、図５は、拡大表示を行った後のメニュー画面の表示の他の態様を概念的に示す平面図である。 In the example shown in FIG. 4, an example in which the enlarged display area is enlarged and displayed on the entire display screen of the display 302 is described. However, it may be configured such that normal display is performed in an area other than the enlarged display area while the enlarged display is completed in the enlarged display area. This display example will be described with reference to FIG. FIG. 5 is a plan view conceptually showing another aspect of the display of the menu screen after the enlarged display.
　図５（ａ）に示すように、図３（ａ）に示す状態のメニュー画面に対して他の態様で拡大表示が行われると、図５（ａ）に示すように、「音声・字幕用メニュー画像」及びその周辺領域を含む拡大表示領域が算出される（具体的には、図５（ａ）中の矩形の線で囲まれた領域が拡大表示領域として算出される）と共に、拡大表示領域中に含まれる主映像やメニュー画像等が、拡大表示領域を超えることなく（言い換えれば、拡大表示領域の外にはみ出ることなく）拡大表示される。つまり、拡大表示領域を虫眼鏡で観察しているかの如き表示態様で、拡大表示領域の拡大表示が行われる。その一方で、拡大表示領域以外の表示領域においては、拡大表示は行われない。つまり、拡大表示領域以外の表示領域に表示される主映像やメニュー画像等は、通常のサイズで表示される。 As shown in FIG. 5A, when enlarged display is performed in another manner on the menu screen in the state shown in FIG. 3A, as shown in FIG. An enlarged display area including the “menu image” and its peripheral area is calculated (specifically, an area surrounded by a rectangular line in FIG. 5A is calculated as an enlarged display area) and enlarged display The main video or menu image included in the area is enlarged and displayed without exceeding the enlarged display area (in other words, without protruding outside the enlarged display area). That is, the enlarged display area is enlarged and displayed in a display manner as if the enlarged display area was observed with a magnifying glass. On the other hand, enlarged display is not performed in display areas other than the enlarged display area. That is, the main video or menu image displayed in the display area other than the enlarged display area is displayed in a normal size.
　また、図３（ａ）に示す状態から図３（ｂ）に示す状態に移動する場合には、図５（ｂ）に示すように、「チャプター用メニュー画像」及びその周辺領域を含む拡大表示領域が算出される（具体的には、図５（ｂ）中の矩形の線で囲まれた領域が拡大表示領域として算出される）と共に、拡大表示領域中に含まれるメニュー画像等が、拡大表示領域を超えることなく拡大表示される。 Further, in the case of moving from the state shown in FIG. 3A to the state shown in FIG. 3B, as shown in FIG. 5B, an enlarged display including the “chapter menu image” and its surrounding area. An area is calculated (specifically, an area surrounded by a rectangular line in FIG. 5B is calculated as an enlarged display area), and a menu image or the like included in the enlarged display area is enlarged. Enlarged display without exceeding the display area.
　このように表示しても、ユーザにとって、現在選択されているメニュー画像を構成するボタンやアイコンや各種文字列等はより一層見やすくなる。 Even if displayed in this way, the buttons, icons, various character strings, etc. that make up the currently selected menu image become even easier for the user to see.
　尚、図５に示す表示態様では、ユーザにより選択されているメニュー選択肢画像を中心とした拡大表示領域が算出されることが好ましい。つまり、図５（ａ）に示す状態においては、「英語５．１ｃｈボタン」を中心とした拡大表示領域が算出されると共に、「英語５．１ｃｈボタン」を中心とした拡大表示が行われることが好ましい。同様に、図５（ｂ）に示す状態においては、「３ボタン」を中心とした拡大表示領域が算出されると共に、「３ボタン」を中心とした拡大表示が行われることが好ましい。 In the display mode shown in FIG. 5, it is preferable that an enlarged display area centering on the menu option image selected by the user is calculated. That is, in the state shown in FIG. 5A, an enlarged display area centered on “English 5.1ch button” is calculated and enlarged display centered on “English 5.1ch button” is performed. Is preferred. Similarly, in the state shown in FIG. 5B, it is preferable that an enlarged display area centered on “3 buttons” is calculated and enlarged display centered on “3 buttons” is performed.
　また、図５に示す表示態様では、ユーザにより選択されているメニュー画像の形状（或いは、大きさ）に合わせて、拡大表示領域の形状（或いは、大きさ）を変えるように構成してもよい。例えば、図５（ａ）に示す状態においては、「音声・字幕用メニュー画像」の形状が縦長であることを考慮して、拡大表示領域の形状が縦長となるようにしてもよい。これにより、メニュー画像をより一層見やすく拡大表示することができる。 Further, the display mode shown in FIG. 5 may be configured to change the shape (or size) of the enlarged display area in accordance with the shape (or size) of the menu image selected by the user. . For example, in the state illustrated in FIG. 5A, the shape of the enlarged display area may be vertically long in consideration of the shape of the “audio / caption menu image” being vertically long. As a result, the menu image can be enlarged and displayed more easily.
　また、図４に示す表示態様及び図５に示す表示態様のいずれにおいても、ディスプレイ３０２の表示画面の大きさに応じて、拡大表示における拡大率を変化させるように構成してもよい。例えば、ディスプレイ３０２の表示画面のサイズが相対的に大きければ、メニュー画像をそれほど拡大させなくともメニュー画像を比較的容易に認識できるため、拡大率を相対的に小さくするように構成してもよい。その一方で、ディスプレイ３０２の表示画面のサイズが相対的に小さければ、メニュー画像を拡大させる必要性が高いため、拡大率を相対的に大きくするように構成してもよい。これにより、より一層見やすい態様でメニュー画像の拡大表示を行うことができる。　本発明は、上述した実施例に限られるものではなく、請求の範囲及び明細書全体から読み取れる発明の要旨或いは思想に反しない範囲で適宜変更可能であり、そのような変更を伴なう表示装置及び方法、並びにコンピュータプログラムもまた本発明の技術的範囲に含まれるものである。 Further, in any of the display mode shown in FIG. 4 and the display mode shown in FIG. 5, the enlargement ratio in the enlarged display may be changed according to the size of the display screen of the display 302. For example, if the size of the display screen of the display 302 is relatively large, the menu image can be recognized relatively easily without enlarging the menu image so much, so the enlargement ratio may be relatively small. . On the other hand, if the size of the display screen of the display 302 is relatively small, it is highly necessary to enlarge the menu image. Therefore, the enlargement ratio may be relatively increased. As a result, the menu image can be enlarged and displayed in a more easily viewable manner. The present invention is not limited to the above-described embodiments, and can be appropriately changed without departing from the spirit or idea of the invention that can be read from the claims and the entire specification, and a display device with such a change And methods and computer programs are also included in the technical scope of the present invention.
