[0046] ディスプレイ姿勢検出部 16は、例えば傾斜センサを備え、ディスプレイ 20が指向す る姿勢方向を検出するようになっている。ここで、姿勢方向とは、例えば、図 1に示さ れたディスプレイ 20の長辺が指向する方向をいい、ディスプレイ姿勢検出部 16は、 ディスプレイ 20の長辺方向と重力方向との角度（以下「姿勢角度」という。）を検知す ることによってディスプレイ 20の姿勢方向を検出するようになって 、る。  [0046] The display posture detection unit 16 includes, for example, a tilt sensor, and detects the posture direction to which the display 20 is directed. Here, the orientation direction refers to, for example, the direction in which the long side of the display 20 shown in FIG. 1 is directed, and the display orientation detection unit 16 determines the angle between the long side direction of the display 20 and the gravity direction (hereinafter “ By detecting the “posture angle”), the orientation direction of the display 20 is detected.
[0047] ディスプレイ制御部 17は、ディスプレイ姿勢検出部 16によって検出されたディスプ レイ 20の姿勢方向に応じた座標で映像をディスプレイ 20に表示するよう映像効果処 理部 18を制御するようになって ヽる。 The display control unit 17 displays the display detected by the display attitude detection unit 16. The video effect processing unit 18 is controlled to display the video on the display 20 with the coordinates corresponding to the posture direction of the ray 20.
[0048] 例えば、ディスプレイ 20の表示状態が図 1に示された縦表示状態 S 11の場合、ディ スプレイ制御部 17は、第 1の座標で映像を表示するよう映像効果処理部 18を制御す るようになっている。 [0048] For example, when the display state of the display 20 is the vertical display state S11 shown in FIG. 1, the display control unit 17 controls the video effect processing unit 18 to display the video at the first coordinates. It has become so.
[0049] また、例えば、ディスプレイ 20の表示状態が図 1に示された横表示状態 S 12、 S15 又は S16の場合、ディスプレイ制御部 17は、第 2の座標で映像を表示するよう映像 効果処理部 18を制御するようになって ヽる。  [0049] Further, for example, when the display state of the display 20 is the horizontal display state S12, S15, or S16 shown in FIG. 1, the display control unit 17 performs the video effect processing so as to display the video at the second coordinates. It comes to control part 18.
[0050] また、例えば、ディスプレイ 20の表示状態が図 1に示された遷移表示状態 S 13又は S14の場合、ディスプレイ制御部 17は、予め定められた座標で映像を表示するよう 映像効果処理部 18を制御するようになっている。なお、ディスプレイ制御部 17は、後 述の遷移時間のデータを予め記憶するメモリ（図示省略)を備えている。  [0050] Also, for example, when the display state of the display 20 is the transition display state S13 or S14 shown in FIG. 1, the display control unit 17 displays the video at predetermined coordinates. 18 is to be controlled. The display control unit 17 includes a memory (not shown) that stores data of transition time described later in advance.
[0051] 映像効果処理部 18は、ディスプレイ制御部 17から出力される制御信号に基づき、 映像信号供給部 11及び伝送部 13の少なくとも一方カゝら出力される映像信号に所定 の映像効果を遷移時間内に施すようになって!/、る。  [0051] Based on the control signal output from the display control unit 17, the video effect processing unit 18 transitions a predetermined video effect to a video signal output from at least one of the video signal supply unit 11 and the transmission unit 13. It will be applied in time!
[0052] ここで、所定の映像効果とは、映像に与える視覚的効果をいい、例えば、映像を回 転、拡大、縮小する処理や、フェードイン、フェードアウト、クロスフェード、オーバーラ ップ合成、ページめくり表示、ワイプ、モザイク等による映像の切替処理、又はこれら の処理を組み合わせた処理等をいう。これらの映像効果を映像に施す際には、ディ スプレイ制御部 17は、各映像効果を施すための制御データを出力し、映像効果処 理部 18は、この制御データに基づ 、て各映像効果を施すようになって!/、る。  [0052] Here, the predetermined video effect refers to a visual effect given to the video, such as a process of rotating, enlarging, or reducing the video, fade-in, fade-out, cross-fade, overlap synthesis, Refers to page switching, wipes, mosaic switching, etc., or a combination of these processes. When these video effects are applied to the video, the display control unit 17 outputs control data for applying each video effect, and the video effect processing unit 18 outputs each video based on the control data. Come to have an effect!
[0053] 例えば、ディスプレイ制御部 17は、映像を回転する映像効果を施す際は、映像の 回転角度を制御データとして出力し、映像をフェードインする映像効果を施す際は、 映像の透過度を制御データとして出力する。なお、これらの制御データを予めメモリ に記憶しておき、ディスプレイ制御部 17が制御データを使用する構成としてもょ ヽ。  [0053] For example, the display control unit 17 outputs the rotation angle of the video as control data when applying the video effect for rotating the video, and sets the video transparency when applying the video effect for fading in the video. Output as control data. It is also possible to store the control data in a memory in advance so that the display control unit 17 uses the control data.
[0054] また、遷移時間とは、映像が切り替わつてから、この切り替わった映像を人間が認識 できるまでに要する時間をいう。例えば、縦表示の映像から横表示の映像に瞬時に 切り替えた場合、一般的に人間は、映像が切り替わった直後に映像の表示内容を認 識することはできず、映像が切り替わってカゝら切り替わった映像を認識するまでに数 秒間程度の時間を要する。この時間を遷移時間という。遷移時間は、例えば 2〜3秒 間程度の時間として設定される。 [0054] The transition time is the time required for a human to be able to recognize the switched video after the video is switched. For example, when switching from a vertically displayed image to a horizontally displayed image instantly, in general, humans recognize the display content of the image immediately after the image is switched. It cannot be recognized, and it takes a few seconds to recognize the switched video after switching the video. This time is called transition time. The transition time is set as a time of about 2 to 3 seconds, for example.
[0055] また、映像効果処理部 18は、映像を回転、拡大又は縮小する回転拡大縮小部 18 aと、映像の切替処理や合成処理を行う映像効果合成部 18bと、合成された映像信 号を記憶する合成用フレームメモリ 18cとを備えている。ここで、回転拡大縮小部 18a 及び映像効果合成部 18bは、それぞれ、本発明の回転拡大縮小部及び映像合成部 を構成している。 [0055] Further, the video effect processing unit 18 includes a rotation enlargement / reduction unit 18a that rotates, enlarges, or reduces a video, a video effect synthesis unit 18b that performs video switching processing and synthesis processing, and a synthesized video signal. And a compositing frame memory 18c. Here, the rotation enlargement / reduction unit 18a and the video effect composition unit 18b constitute a rotation enlargement / reduction unit and a video composition unit of the present invention, respectively.
[0056] 具体的には、回転拡大縮小部 18aは、デコーダ 15から映像信号を入力し、この映 像信号に基づく映像を回転、拡大又は縮小して映像効果合成部 18bに出力するよう になっている。なお、回転拡大縮小部 18aは、入力された映像信号に基づく映像を 常に回転、拡大又は縮小するわけでなぐ例えば、ディスプレイ制御部 17から回転角 度を 0度に設定する制御信号が入力された場合は映像の回転は行わない。また、回 転拡大縮小部 18aは、映像の回転、拡大又は縮小のうちの一つのみを実行するもの ではなぐそれぞれを組み合わせた処理を行うこともできるようになって!/、る。  Specifically, the rotation enlargement / reduction unit 18a receives the video signal from the decoder 15, rotates, enlarges or reduces the video based on the video signal, and outputs the video to the video effect synthesis unit 18b. ing. The rotation enlargement / reduction unit 18a does not always rotate, enlarge or reduce the video based on the input video signal. For example, the control signal for setting the rotation angle to 0 degree is input from the display control unit 17. In this case, the image is not rotated. In addition, the rotation enlargement / reduction unit 18a can also perform a process that combines not only one that performs only one of rotation, enlargement, and reduction of the image!
[0057] また、映像効果合成部 18bは、例えば現在の時刻情報を表した文字列や電波受信 強度状態を示すアイコンの映像等 (以下「アイコン映像等」という。）と、回転拡大縮小 部 18aによって処理された映像とを合成したり、回転した映像や合成した映像等に対 してクロスフェードやページめくり表示等による映像の切替処理を行ったりするように なっている。  [0057] Further, the video effect composition unit 18b includes, for example, a character string representing the current time information, an icon video indicating the radio wave reception intensity state (hereinafter referred to as "icon video etc."), and a rotation scaling unit 18a. The video processed by the above is synthesized, and the video switching processing by crossfading, page turning display, etc. is performed on the rotated video, synthesized video, and the like.
[0058] また、合成用フレームメモリ 18cは、映像効果合成部 18bによって合成された映像 信号や映像効果処理部 18に入力された映像信号を記憶するようになっている。  [0058] The synthesizing frame memory 18c stores the video signal synthesized by the video effect synthesizing unit 18b and the video signal input to the video effect processing unit 18.
[0059] 表示用フレームメモリ 19は、例えば RAMで構成され、映像効果処理部 18によって 映像効果が施された映像信号を記憶するようになっている。ディスプレイ 20は、例え ば液晶ディスプレイで構成され、表示用フレームメモリ 19に記憶された映像信号に基 づく映像を表示するようになって 、る。  [0059] The display frame memory 19 is constituted by, for example, a RAM, and stores a video signal to which a video effect is applied by the video effect processing unit 18. The display 20 is composed of a liquid crystal display, for example, and displays an image based on the image signal stored in the display frame memory 19.
[0060] 次に、本実施の形態の携帯電話機 10の動作について説明する。なお、図 3 (a)〜 図 3 (c)に例示された映像効果をそれぞれ第 1〜第 3の映像効果とし、図 1に示され た縦表示状態 Sl lと横表示状態 S12との間で携帯電話機 10の姿勢方向が切り替わ る際の動作を例に挙げて説明する。 [0060] Next, the operation of the mobile phone 10 of the present embodiment will be described. The video effects illustrated in FIGS. 3 (a) to 3 (c) are the first to third video effects, respectively, and are shown in FIG. The operation when the orientation direction of the mobile phone 10 is switched between the vertical display state Sl l and the horizontal display state S12 will be described as an example.
[0061] (第 1の映像効果の処理例）  [0061] (First image effect processing example)
図 3 (a)において、ディスプレイ 20に縦表示された縦表示用の映像 31aと、横表示 された横表示用の映像 31cと、縦表示用の映像 31aから横表示用の映像 31cに至る 遷移状態における遷移表示用の映像 3 lbとが示されて 、る。遷移表示用の映像 3 lb は、遷移時間内に入力される動映像が遷移時間の経過とともに回転されながら再生 されるものである。以下、図 4に示されたフローチャートを用いて動作を説明する。  In Fig. 3 (a), the vertical display video 31a displayed vertically on the display 20, the horizontal display video 31c displayed horizontally, and the transition from the vertical display video 31a to the horizontal display video 31c. A 3 lb video for state transition display is shown. The transition display video 3 lb is played while the moving video input within the transition time is rotated as the transition time elapses. The operation will be described below with reference to the flowchart shown in FIG.
[0062] まず、ディスプレイ姿勢検出部 16によって、傾斜センサが検知した姿勢角度に基づ いて表示状態を切り替える力否かが判断される (ステップ S21)。例えば、予め姿勢角 度の閾値を設定しておき、傾斜センサが検知した姿勢角度が閾値を超えたとき、ディ スプレイ姿勢検出部 16によって、表示状態を切り替えると判断される。  [0062] First, the display attitude detection unit 16 determines whether or not the display state is switched based on the attitude angle detected by the tilt sensor (step S21). For example, a threshold value of the posture angle is set in advance, and when the posture angle detected by the tilt sensor exceeds the threshold value, the display posture detection unit 16 determines to switch the display state.
[0063] ステップ S21にお 、て、表示状態を切り替えると判断された場合は、ディスプレイ姿 勢検出部 16によって、表示状態が縦表示状態 S11 (図 1参照)から横表示状態 S12 (図 1参照）に切り替わるか否かが判断され (ステップ S22)、表示状態を切り替えると 判断されなかった場合は、ステップ S21を繰り返す。  [0063] If it is determined in step S21 that the display state is to be switched, the display state detection unit 16 changes the display state from the vertical display state S11 (see Fig. 1) to the horizontal display state S12 (see Fig. 1). ) Is determined (step S22). If it is not determined to switch the display state, step S21 is repeated.
[0064] ステップ S22において、表示状態が縦表示状態 S11から横表示状態 S12に切り替 わると判断された場合は、ディスプレイ制御部 17によって、映像の回転角度及び拡 大率が設定される (ステップ S23)。  [0064] In step S22, when it is determined that the display state is switched from the vertical display state S11 to the horizontal display state S12, the display control unit 17 sets the rotation angle and the enlargement ratio of the video (step S23). ).
[0065] 具体的には、図 1に示された縦表示状態 S11から横表示状態 S12に遷移する場合 は、姿勢角度は、ほぼ 0度からほぼ 90度に変化することになるので、ディスプレイ制 御部 17は、例えば回転角度を 5度に設定し、縦表示用の映像 31aを回転角度 5度ず つのステップで回転しながら徐々に拡大して、遷移時間が終了したときに横表示用 の映像 31cとなるよう拡大率を設定する。  Specifically, when transitioning from the vertical display state S11 shown in FIG. 1 to the horizontal display state S12, the attitude angle changes from approximately 0 degrees to approximately 90 degrees. For example, the control unit 17 sets the rotation angle to 5 degrees, and gradually expands the image 31a for vertical display while rotating the rotation angle by 5 steps in steps of 5 degrees. Set the enlargement ratio so that the image is 31c.
[0066] さらに、回転拡大縮小部 18aによって、ディスプレイ制御部 17が設定した回転角度 及び拡大率で、入力されたフレームの映像信号に基づく映像と、アイコン等とがそれ ぞれ回転及び拡大された後、映像効果合成部 18bによって、両者が合成される (ステ ップ S24)。 [0067] 次いで、回転拡大縮小部 18aによって、合成された映像の信号が表示用フレームメ モリ 19に格納される（ステップ S 25)。 [0066] Further, the image based on the video signal of the input frame and the icon or the like are rotated and enlarged by the rotation enlargement / reduction unit 18a at the rotation angle and magnification set by the display control unit 17, respectively. Thereafter, both are synthesized by the video effect synthesis unit 18b (step S24). Next, the combined video signal is stored in the display frame memory 19 by the rotation scaling unit 18a (step S25).
[0068] 次いで、ディスプレイ 20によって、表示用フレームメモリ 19から映像信号が読み出 され、映像が表示される (ステップ S26)。  [0068] Next, the video signal is read from the display frame memory 19 by the display 20, and the video is displayed (step S26).
[0069] そして、ディスプレイ制御部 17によって、遷移時間内力否かが判断され (ステップ S 27)、遷移時間内と判断された場合は、ステップ S24からステップ S27までの処理が 、フレーム毎に入力される動映像に対して繰り返して実行され、遷移時間内と判断さ れなかった場合は処理を終了する。  [0069] Then, the display control unit 17 determines whether or not the force is within the transition time (step S27). If it is determined that the power is within the transition time, the processing from step S24 to step S27 is input for each frame. This process is repeated for a moving video, and if it is not determined that it is within the transition time, the process ends.
[0070] 一方、ステップ S22において、表示状態が横表示状態 S12から縦表示状態 S11に 切り替わると判断された場合は、ディスプレイ制御部 17によって、映像の回転角度及 び縮小率が設定される (ステップ S31)。具体的には、図 1に示された横表示状態 S1 2から縦表示状態 S 11に遷移する場合は、姿勢角度は、ほぼ 90度からほぼ 0度に変 化することになるので、ディスプレイ制御部 17は、例えば回転角度を 5度に設定し、 横表示用の映像 31cを 5度のステップで回転しながら徐々に縮小して、予め定められ た遷移時間を経過した時点で縦表示用の映像 3 laとなるよう縮小率を設定する。  [0070] On the other hand, if it is determined in step S22 that the display state is switched from the horizontal display state S12 to the vertical display state S11, the display control unit 17 sets the rotation angle and the reduction ratio of the video (step S22). S31). Specifically, when transitioning from the horizontal display state S1 2 shown in FIG. 1 to the vertical display state S11, the attitude angle changes from approximately 90 degrees to approximately 0 degrees. For example, the unit 17 sets the rotation angle to 5 degrees, and gradually reduces the horizontal display image 31c while rotating it in steps of 5 degrees, and when a predetermined transition time elapses, Set the reduction ratio to be 3 la.
[0071] さらに、回転拡大縮小部 18aによって、ディスプレイ制御部 17が設定した回転角度 及び縮小率で、入力されたフレームの映像信号に基づく映像と、アイコン等とがそれ ぞれ回転及び縮小された後、映像効果合成部 18bによって、両者が合成される (ステ ップ S32)。  [0071] Further, the image based on the video signal of the input frame, the icon, and the like are rotated and reduced by the rotation enlargement / reduction unit 18a at the rotation angle and reduction rate set by the display control unit 17, respectively. Thereafter, both are synthesized by the video effect synthesis unit 18b (step S32).
[0072] そして、前述のステップ S25からステップ S27に対応したステップ S33からステップ S35までの処理が実行される。  [0072] Then, the processing from Step S33 to Step S35 corresponding to Step S25 to Step S27 described above is executed.
[0073] なお、ステップ S24からステップ S27までの処理を繰り返す場合は、ステップ S24に おいて合成した映像の映像信号を合成する毎に合成用フレームメモリ 18cに記憶さ せ、合成用フレームメモリ 18cに記憶された映像信号を用いて、映像の回転及び拡 大を行うようにしてもよい。ステップ S31からステップ S35までの処理を繰り返す場合 も同様である。  [0073] When the processing from step S24 to step S27 is repeated, the video signal of the video synthesized in step S24 is stored in the synthesis frame memory 18c every time it is synthesized, and is stored in the synthesis frame memory 18c. The stored video signal may be used to rotate and enlarge the video. The same applies when the processing from step S31 to step S35 is repeated.
[0074] また、動映像及びアイコン等を回転、拡大し、合成する例を挙げて説明したが、本 発明はこれに限定されるものではなぐ動映像のみを回転、拡大してもよいし、任意 の 1つのフレームの映像を静止映像として回転、拡大してもよい。 [0074] Further, although an example of rotating, enlarging, and synthesizing moving images and icons, etc. has been described, the present invention is not limited to this, and only moving images may be rotated and enlarged. Any One frame image may be rotated and enlarged as a still image.
[0075] (第 2の映像効果の処理例） [0075] (Second image effect processing example)
図 3 (b)において、ディスプレイ 20に縦表示された縦表示用の映像 32aと、横表示 された横表示用の映像 32cと、縦表示用の映像 32aから横表示用の映像 32cに至る 遷移状態における遷移表示用の映像 32bとが示されている。遷移表示用の映像 32b は、遷移時間の経過とともにクロスフェード効果による処理で映像が表示されるもの である。クロスフェード効果とは、例えば、縦表示用の映像が遷移時間の経過とともに フェードアウトしながら、横表示用の映像が遷移時間の経過とともに縦表示用の映像 に重なってフェードインしていくことをいう。以下、図 5に示されたフローチャートを用 いて動作を説明する。なお、図 5においては、フェードアウトを FO、フェードインを FI と表記している。  In Fig. 3 (b), the video image 32a for vertical display displayed vertically on the display 20, the video image 32c for horizontal display displayed horizontally, and the transition from the video image 32a for vertical display to the video 32c for horizontal display. An image 32b for transition display in the state is shown. The video 32b for transition display is a video that is displayed by processing with a crossfade effect as the transition time elapses. The crossfade effect means, for example, that a video for vertical display fades out as the transition time elapses, while a video for horizontal display fades in over the video for vertical display as the transition time elapses. . The operation will be described below using the flowchart shown in FIG. In Fig. 5, fade-out is expressed as FO and fade-in as FI.
[0076] まず、ディスプレイ姿勢検出部 16によって、傾斜センサが検知した姿勢角度に基づ いて表示状態を切り替える力否かが判断される (ステップ S21)。  [0076] First, the display posture detection unit 16 determines whether or not the display state is switched based on the posture angle detected by the tilt sensor (step S21).
[0077] ステップ S21にお 、て、表示状態を切り替えると判断された場合は、ディスプレイ姿 勢検出部 16によって、表示状態が縦表示状態 S11 (図 1参照)から横表示状態 S12 (図 1参照）に切り替わるか否かが判断され (ステップ S22)、表示状態を切り替えると 判断されなかった場合は、ステップ S21を繰り返す。  [0077] If it is determined in step S21 that the display state is to be switched, the display state detection unit 16 changes the display state from the vertical display state S11 (see FIG. 1) to the horizontal display state S12 (see FIG. 1). ) Is determined (step S22). If it is not determined to switch the display state, step S21 is repeated.
[0078] ステップ S22において、表示状態が縦表示状態 S11から横表示状態 S12に切り替 わると判断された場合は、ディスプレイ制御部 17によって、縦表示状態 S11において 映像効果処理部 18に最後に入力されたフレームの映像データが回転拡大縮小部 1 8aを介して合成用フレームメモリ 18cに格納される（ステップ S41)。  [0078] In step S22, when it is determined that the display state is switched from the vertical display state S11 to the horizontal display state S12, the display control unit 17 finally inputs the video image processing unit 18 in the vertical display state S11. The video data of the obtained frame is stored in the compositing frame memory 18c through the rotation enlargement / reduction unit 18a (step S41).
[0079] さらに、ディスプレイ制御部 17によって、縦表示状態 S11から横表示状態 S12に切 替表示するための映像の回転角度及び拡大率と、映像をフェードイン、フェードァゥ トする際の透過度の初期値及びステップ値とが設定される (ステップ S42)。  [0079] Further, the display controller 17 causes the rotation angle and magnification of the image to be switched from the vertical display state S11 to the horizontal display state S12, and the initial transparency when the image is faded in and faded out. A value and a step value are set (step S42).
[0080] 具体的には、図 1に示された縦表示状態 S11から横表示状態 S12に遷移する場合 は、姿勢角度は、ほぼ 0度からほぼ 90度に変化することになるので、ディスプレイ制 御部 17は、横表示用の映像を得るために回転角度を 90度に設定し、縦表示状態 S 11での映像のサイズと、横表示状態 S 12での映像のサイズとから拡大率を設定する [0081] また、透過度は、例えば 256段階で設定され、ある映像に対し、背景映像が全く透 過しな 、「0」カゝら背景映像が全部透過する「255」の数値で指定される。映像をフエ ードアウトする際の透過度の初期値は例えば「0」に設定され、ステップ値は「 + 1」に 設定される。また、映像をフェードインする際の透過度の初期値は例えば「255」に設 定され、ステップ値は「一 1」に設定される。 Specifically, when transitioning from the vertical display state S11 shown in FIG. 1 to the horizontal display state S12, the attitude angle changes from approximately 0 degrees to approximately 90 degrees. Control unit 17 sets the rotation angle to 90 degrees in order to obtain an image for horizontal display, and sets the enlargement ratio from the size of the image in vertical display state S11 and the size of the image in horizontal display state S12. Set [0081] Further, the transparency is set in, for example, 256 levels, and is specified by a numerical value of "255" that allows the background video to be completely transparent to a certain video, such as "0". The For example, the initial transparency value when the video is faded out is set to “0”, and the step value is set to “+1”. Also, the initial value of transparency when fading in video is set to “255”, for example, and the step value is set to “1”.
[0082] 引き続き、映像効果合成部 18bによって、合成用フレームメモリ 18cに格納された 最終フレームの映像信号が読み出され、この映像信号に基づいた縦表示用の映像 と、アイコン映像等とが合成され、ステップ S42において設定された透過度でフェード アウトするための映像透過処理が行われる（ステップ S43)。  [0082] Subsequently, the video effect synthesis unit 18b reads out the video signal of the final frame stored in the synthesis frame memory 18c, and synthesizes the video for vertical display based on this video signal, the icon video, and the like. Then, a video transmission process for fading out with the transparency set in step S42 is performed (step S43).
[0083] 一方、このステップ S43と並行して、回転拡大縮小部 18aによって、ディスプレイ制 御部 17が設定した回転角度及び拡大率で、縦表示用の映像とアイコン等とがそれ ぞれ回転及び拡大された後、映像効果合成部 18bによって、両者が合成され、ステ ップ S42において設定された透過度でフェードインするための映像透過処理が行わ れる（ステップ S44)。  On the other hand, in parallel with step S43, the rotation display unit 17a rotates and enlarges the image for vertical display, the icon, and the like at the rotation angle and magnification set by the display control unit 17, respectively. After the enlargement, both are combined by the video effect combining unit 18b, and a video transmission process for fading in with the transparency set in step S42 is performed (step S44).
[0084] 引き続き、映像効果合成部 18bによって、ステップ S43で生成された映像と、ステツ プ S44で生成された映像とが合成され (ステップ S45)、合成された映像の信号は、 表示用フレームメモリ 19に格納される（ステップ S46)。  [0084] Subsequently, the video effect synthesis unit 18b synthesizes the video generated in step S43 and the video generated in step S44 (step S45), and the synthesized video signal is displayed in the display frame memory. 19 (step S46).
[0085] 次いで、ディスプレイ 20によって、表示用フレームメモリ 19から映像信号が読み出 され、クロスフェード処理された映像が表示される (ステップ S47)。  [0085] Next, the video signal is read from the display frame memory 19 by the display 20, and the video subjected to the cross-fade process is displayed (step S47).
[0086] そして、ディスプレイ制御部 17によって、遷移時間内力否かが判断される（ステップ S48)。ここで、遷移時間内と判断された場合は、ステップ S43からステップ S48まで の処理が、ステップ S43及びステップ S44にお!/、て透過度を所定のステップ値で変 更しながら繰り返して実行され、ディスプレイ 20に表示された縦表示用の静止映像は フェードアウトし、横表示用の動映像はフェードインする。なお、ステップ S48におい て、遷移時間内と判断されな力 た場合は処理を終了する。  [0086] Then, the display control unit 17 determines whether or not the force is within the transition time (step S48). If it is determined that the time is within the transition time, the processing from step S43 to step S48 is repeatedly executed while changing the transparency to a predetermined step value in steps S43 and S44. The still image for vertical display displayed on the display 20 fades out, and the moving image for horizontal display fades in. If it is determined in step S48 that the force is not within the transition time, the process ends.
[0087] 一方、ステップ S22において、表示状態が横表示状態 S12から縦表示状態 S11に 切り替わると判断された場合は、ディスプレイ制御部 17によって、横表示状態 S12に おいて映像効果処理部 18に入力された最終フレームの映像データが回転拡大縮小 部 18aを介して合成用フレームメモリ 18cに格納される（ステップ S51)。 [0087] On the other hand, if it is determined in step S22 that the display state is switched from the horizontal display state S12 to the vertical display state S11, the display control unit 17 changes the display state to the horizontal display state S12. Then, the video data of the last frame input to the video effect processing unit 18 is stored in the synthesizing frame memory 18c via the rotation enlargement / reduction unit 18a (step S51).
[0088] さらに、ディスプレイ制御部 17によって、横表示状態 S 12から縦表示状態 S 11に切 替表示するための映像の回転角度及び縮小率と、映像をフェードイン、フェードァゥ トする際の透過度の初期値及びステップ値とが設定される (ステップ S52)。  [0088] Further, the display control unit 17 causes the video rotation angle and reduction ratio to be switched from the horizontal display state S12 to the vertical display state S11, and the transparency when the video is faded in and faded out. The initial value and step value are set (step S52).
[0089] 具体的には、図 1に示された横表示状態 S 12から縦表示状態 S 11に遷移する場合 は、姿勢角度は、ほぼ 90度からほぼ 0度に変化することになるので、ディスプレイ制 御部 17は、縦表示用の映像を得るために回転角度を 90度に設定し、縦表示状態 S 11での映像のサイズと、横表示状態 S 12での映像のサイズとから縮小率を設定する 。また、透過度は、前述のステップ S42における設定と同様に設定される。  [0089] Specifically, when transitioning from the horizontal display state S12 shown in FIG. 1 to the vertical display state S11, the posture angle changes from approximately 90 degrees to approximately 0 degrees. The display control unit 17 sets the rotation angle to 90 degrees to obtain an image for vertical display, and reduces the image size in the vertical display state S 11 and the image size in the horizontal display state S 12. Set the rate. Further, the transparency is set in the same manner as the setting in step S42 described above.
[0090] 引き続き、映像効果合成部 18bによって、合成用フレームメモリ 18cに格納された 最終フレームの映像信号が読み出され、この映像信号に基づいた横表示用の映像 と、アイコン映像等とが合成され、ステップ S52において設定された透過度でフェード アウトするための映像透過処理が行われる（ステップ S53)。  Subsequently, the video effect synthesizing unit 18b reads out the video signal of the final frame stored in the synthesizing frame memory 18c, and the video for horizontal display based on the video signal is synthesized with the icon video and the like. Then, video transmission processing for fading out with the transparency set in step S52 is performed (step S53).
[0091] 一方、このステップ S53と並行して、回転拡大縮小部 18aによって、ディスプレイ制 御部 17が設定した回転角度及び縮小率で、横表示用の映像とアイコン等とがそれ ぞれ回転及び縮小された後、映像効果合成部 18bによって、両者が合成され、ステ ップ S52において設定された透過度でフェードインするための映像透過処理が行わ れる（ステップ S 54)。  On the other hand, in parallel with step S53, the rotation display unit 17a rotates and enlarges the horizontal display image and the icon, etc., respectively, at the rotation angle and reduction rate set by the display control unit 17. After the reduction, both are combined by the video effect combining unit 18b, and video transmission processing for fading in with the transparency set in step S52 is performed (step S54).
[0092] 引き続き、映像効果合成部 18bによって、ステップ S53で生成された映像と、ステツ プ S54で生成された映像とが合成され (ステップ S55)、以下、前述のステップ S46か らステップ S48に対応したステップ S56からステップ S58までの処理が実行される。  [0092] Subsequently, the video effect synthesis unit 18b synthesizes the video generated in step S53 and the video generated in step S54 (step S55), and corresponds to steps S46 to S48 described above. The processing from step S56 to step S58 is executed.
[0093] なお、静止映像をフェードアウトし、動映像をフェードインする例を挙げて説明した 力 本発明はこれに限定されるものではなぐ例えば動映像をフェードアウトし、静止 映像をフェードインする構成としてもょ 、。  [0093] Note that the power described with reference to an example of fading out a still image and fading in a moving image is not limited to this. For example, the configuration is such that a moving image is faded out and a still image is faded in. Well ...
[0094] (第 3の映像効果の処理例）  [0094] (Third example of video effect processing)
図 3 (c)において、ディスプレイ 20に縦表示された縦表示用の映像 33aと、横表示 された横表示用の映像 33cと、縦表示用の映像 33aから横表示用の映像 33cに至る 遷移状態における遷移表示用の映像 33bとが示されている。遷移表示用の映像 33b は、遷移時間の経過とともに、縦表示用の動映像が縮小されながら横表示用の動映 像が拡大される処理 (以下「縮小拡大処理」という。）によるものである。以下、図 6に 示されたフローチャートを用いて動作を説明する。 In FIG. 3 (c), the video 33a for vertical display displayed vertically on the display 20, the video 33c for horizontal display displayed horizontally, and the video 33a for vertical display from the video 33a for horizontal display. A video 33b for transition display in the transition state is shown. The video 33b for transition display is obtained by processing (hereinafter referred to as “reduction / enlargement processing”) in which the video for horizontal display is enlarged while the video for vertical display is reduced as the transition time elapses. . The operation will be described below with reference to the flowchart shown in FIG.
[0095] まず、ディスプレイ姿勢検出部 16によって、傾斜センサが検知した姿勢角度に基づ いて表示状態を切り替える力否かが判断される (ステップ S21)。  [0095] First, the display attitude detection unit 16 determines whether or not the display state is switched based on the attitude angle detected by the tilt sensor (step S21).
[0096] ステップ S21にお 、て、表示状態を切り替えると判断された場合は、ディスプレイ姿 勢検出部 16によって、表示状態が縦表示状態 S11 (図 1参照)から横表示状態 S12 (図 1参照）に切り替わるか否かが判断され (ステップ S22)、表示状態を切り替えると 判断されなかった場合は、ステップ S21を繰り返す。  [0096] If it is determined in step S21 that the display state is to be switched, the display state detection unit 16 changes the display state from the vertical display state S11 (see FIG. 1) to the horizontal display state S12 (see FIG. 1). ) Is determined (step S22). If it is not determined to switch the display state, step S21 is repeated.
[0097] ステップ S22において、表示状態が縦表示状態 S11から横表示状態 S12に切り替 わると判断された場合は、ディスプレイ制御部 17によって、縦表示用の映像を横表 示用の映像にするための回転角度と、縮小拡大処理に用いる縦表示用の映像の縮 小率及び横表示用の映像の拡大率とが設定される (ステップ S61)。  [0097] When it is determined in step S22 that the display state is switched from the vertical display state S11 to the horizontal display state S12, the display control unit 17 converts the vertical display image into a horizontal display image. , And the vertical display video reduction ratio and horizontal display video enlargement ratio used for the reduction / enlargement processing are set (step S61).
[0098] 具体的には、図 1に示された縦表示状態 S11から横表示状態 S12に遷移する場合 は、姿勢角度は、ほぼ 0度からほぼ 90度に変化することになるので、ディスプレイ制 御部 17は、横表示用の映像を得るために回転角度を 90度に設定する。また、縮小 拡大処理に用いる縦表示用の映像の縮小率は、図 3に示すように、縦表示用の動映 像が点 Dに向力つて円滑に縮小されるよう複数のステップ値で設定される。また、縮 小拡大処理に用いる横表示用の映像の拡大率は、横表示用の動映像が点 Bに向か つて円滑に拡大されるよう複数のステップ値で設定される。  Specifically, when transitioning from the vertical display state S11 shown in FIG. 1 to the horizontal display state S12, the posture angle changes from approximately 0 degrees to approximately 90 degrees. Control unit 17 sets the rotation angle to 90 degrees in order to obtain an image for horizontal display. In addition, the reduction ratio of the video for vertical display used for reduction / enlargement processing is set with multiple step values so that the video for vertical display is smoothly reduced toward point D as shown in Fig. 3. Is done. Also, the enlargement ratio of the video for horizontal display used in the reduction / enlargement process is set with multiple step values so that the video for horizontal display is smoothly enlarged toward point B.
[0099] 引き続き、映像効果合成部 18bによって、ディスプレイ制御部 17が設定した縮小率 で縦表示用の映像が縮小され、この映像とアイコン映像等とが合成される (ステップ S 62)。一方、回転拡大縮小部 18aによって、ディスプレイ制御部 17が設定した回転角 度及び拡大率で、横表示用の映像とアイコン等とがそれぞれ回転及び拡大された後 、映像効果合成部 18bによって、両者が合成される (ステップ S63)。  Subsequently, the video effect synthesis unit 18b reduces the video for vertical display at the reduction rate set by the display control unit 17, and synthesizes this video with the icon video (step S62). On the other hand, the image for horizontal display and the icon and the like are rotated and enlarged by the rotation enlargement / reduction unit 18a at the rotation angle and enlargement ratio set by the display control unit 17, respectively. Are synthesized (step S63).
[0100] 引き続き、映像効果合成部 18bによって、ステップ S62で生成された映像と、ステツ プ S63で生成された映像とが合成され (ステップ S64)、合成された映像の信号は、 表示用フレームメモリ 19に格納される（ステップ S65)。ステップ S64における合成は 、例えば、縦表示用の映像の上に横表示用の映像を重ねる合成や、縦表示用の映 像及び横表示用の映像にそれぞれ透過率を設定して重ねる合成等がある。 [0100] Subsequently, the video effect synthesis unit 18b synthesizes the video generated in step S62 and the video generated in step S63 (step S64), and the synthesized video signal is It is stored in the display frame memory 19 (step S65). The composition in step S64 includes, for example, composition in which the image for horizontal display is superimposed on the image for vertical display, composition in which the transmittance is set on the image for vertical display and the image for horizontal display, respectively. is there.
[0101] 次いで、ディスプレイ 20によって、表示用フレームメモリ 19から映像信号が読み出 され、縮小拡大処理された映像が表示される (ステップ S66)。  Next, the video signal is read from the display frame memory 19 by the display 20, and the reduced / enlarged video is displayed (step S66).
[0102] そして、ディスプレイ制御部 17によって、遷移時間内力否かが判断される（ステップ S67)。ここで、遷移時間内と判断された場合は、ステップ S62からステップ S67まで の処理力 ステップ S62及びステップ S63において縮小率及び拡大率を変更しなが ら繰り返して実行され、遷移時間の経過とともに、ディスプレイ 20に表示された縦表 示用の動映像が縮小されながら横表示用の動映像が拡大される。一方、ステップ S6 7において、遷移時間内と判断されな力つた場合は処理を終了する。  [0102] Then, the display control unit 17 determines whether or not the force is within the transition time (step S67). Here, if it is determined that the transition time is within, the processing power from step S62 to step S67 is repeatedly executed in steps S62 and S63 while changing the reduction ratio and the enlargement ratio. The moving image for horizontal display is enlarged while the moving image for vertical display displayed on the display 20 is reduced. On the other hand, if it is determined in step S67 that the transition time is not reached, the process is terminated.
[0103] 一方、ステップ S22において、表示状態が横表示状態 S12から縦表示状態 S11に 切り替わると判断された場合は、ディスプレイ制御部 17によって、縦表示状態 S11と 横表示状態 S 12との間で切替表示するための映像の回転角度と、縮小拡大処理に 用いる横表示用の映像の縮小率及び縦表示用の映像の拡大率とが設定される (ステ ップ S71)。  [0103] On the other hand, if it is determined in step S22 that the display state is switched from the horizontal display state S12 to the vertical display state S11, the display control unit 17 determines whether the display state is between the vertical display state S11 and the horizontal display state S12. The rotation angle of the video for switching display, the reduction rate of the video for horizontal display used for the reduction / enlargement processing, and the enlargement rate of the video for vertical display are set (step S71).
[0104] 具体的には、図 1に示された縦表示状態 S11から横表示状態 S12に遷移する場合 は、姿勢角度は、ほぼ 90度からほぼ 0度に変化することになるので、ディスプレイ制 御部 17は、縦表示用の映像を得るために回転角度を 90度に設定する。また、縮小 拡大処理に用 、る横表示用の映像の縮小率及び縦表示用の映像の拡大率は、図 3 (c)に示された矢印の示す方向とは逆方向になるよう設定される。すなわち、横表示 用の映像の縮小率は、横表示用の動映像が点 Aに向力つて縮小されるよう設定され 、縦表示用の映像の拡大率は、縦表示用の動映像が点 Cに向カゝつて拡大されるよう 設定される。  Specifically, when transitioning from the vertical display state S11 shown in FIG. 1 to the horizontal display state S12, the posture angle changes from approximately 90 degrees to approximately 0 degrees. Control unit 17 sets the rotation angle to 90 degrees in order to obtain an image for vertical display. In addition, the reduction ratio of the image for horizontal display and the enlargement ratio of the image for vertical display used for the reduction / enlargement process are set to be opposite to the directions indicated by the arrows shown in FIG. The In other words, the horizontal display video reduction ratio is set so that the horizontal display video is reduced toward point A, and the vertical display video enlargement ratio is the vertical display video. It is set to be enlarged toward C.
[0105] 引き続き、映像効果合成部 18bによって、ディスプレイ制御部 17が設定した縮小率 で横表示用の映像が縮小され、この映像とアイコン映像等とが合成される (ステップ S 72)。一方、回転拡大縮小部 18aによって、ディスプレイ制御部 17が設定した回転角 度及び拡大率で、縦表示用の映像及びアイコン等がそれぞれ回転及び拡大された 後、映像効果合成部 18bによって、両者が合成される (ステップ S73)。 Subsequently, the video effect synthesis unit 18b reduces the horizontal display video at the reduction rate set by the display control unit 17, and the video and the icon video are synthesized (step S72). On the other hand, the rotation enlargement / reduction unit 18a has rotated and enlarged the image and icons for vertical display at the rotation angle and enlargement rate set by the display control unit 17, respectively. Thereafter, both are synthesized by the video effect synthesis unit 18b (step S73).
[0106] 引き続き、映像効果合成部 18bによって、ステップ S72で生成された映像と、ステツ プ S73で生成された映像とが合成され (ステップ S 74)、以下、前述のステップ S65か らステップ S67に対応したステップ S75からステップ S77までの処理が実行される。  [0106] Subsequently, the video effect synthesis unit 18b synthesizes the video generated in step S72 and the video generated in step S73 (step S74). Hereinafter, steps S65 to S67 are performed. The corresponding processing from step S75 to step S77 is executed.
[0107] なお、縮小拡大処理を縦表示用の動映像及び横表示用の動映像で実施する例を 挙げて説明したが、本発明はこれに限定されるものではなぐ例えば縦表示用の静 止映像及び横表示用の静止映像で縮小拡大処理を実施する構成としてもよい。  [0107] Although the example in which the reduction / enlargement processing is performed on a moving image for vertical display and a moving image for horizontal display has been described, the present invention is not limited to this, for example, a static image for vertical display. A configuration may be adopted in which the reduction / enlargement process is performed on the still image and the still image for horizontal display.
[0108] また、縮小拡大処理は、図 3 (c)の映像 33bに示された映像の配置位置や拡大及 び縮小方向に限定されるものではな 、。  [0108] Further, the reduction / enlargement processing is not limited to the arrangement position or enlargement / reduction direction of the video shown in the video 33b of Fig. 3 (c).
[0109] 以上のように、本実施の形態の携帯電話機 10によれば、ディスプレイ姿勢検出部 1 6は、ディスプレイ 20が指向する姿勢方向を検出し、映像効果処理部 18は、ディスプ レイ 20の姿勢方向が遷移する遷移時間内において所定の映像効果を施す構成とし たので、映像の表示方向を見栄えよく円滑に切り替えることができる。  As described above, according to the mobile phone 10 of the present embodiment, the display posture detection unit 16 detects the posture direction to which the display 20 is directed, and the video effect processing unit 18 is connected to the display 20. Since the predetermined video effect is applied within the transition time in which the posture direction transitions, the display direction of the video can be switched smoothly with good appearance.
[0110] なお、前述の実施の形態において、遷移時間を 2〜3秒間程度の時間として予め 設定しておく構成を例に挙げて説明したが、本発明はこれに限定されるものではなく 、例えば使用者が携帯電話機 10の姿勢方向を変更するのに要する平均的な時間を 予め遷移時間として設定する構成としても同様の効果が得られる。また、ディスプレイ [0110] In the above-described embodiment, the configuration in which the transition time is set in advance as a time of about 2 to 3 seconds has been described as an example. However, the present invention is not limited to this, For example, the same effect can be obtained when the average time required for the user to change the orientation direction of the mobile phone 10 is set in advance as the transition time. Also display
20が独立して物理的に回転する構成のものでは、ディスプレイ姿勢検出部 16がディ スプレイ 20の回転角度を検出する構成として回転開始から回転完了までの時間を遷 移時間としてもよい。 In the configuration in which 20 is physically rotated independently, the display attitude detection unit 16 may detect the rotation angle of the display 20 and the time from the start of rotation to the completion of rotation may be used as the transition time.
[0111] また、前述の実施の形態において、図 1に示された縦表示状態 S 11と横表示状態 S 12との間において映像効果を施す構成を例に挙げて説明したが、本発明はこれ〖こ 限定されるものではなぐ例えば縦表示状態 S11と横表示状態 S15との間において 映像効果を施す構成としても同様の効果が得られる。  [0111] In the above-described embodiment, the configuration in which the video effect is applied between the vertical display state S11 and the horizontal display state S12 illustrated in Fig. 1 has been described as an example. For example, a similar effect can be obtained by applying a video effect between the vertical display state S11 and the horizontal display state S15.
[0112] また、前述の実施の形態において、所定の映像効果を動映像や静止映像に施す 構成を例に挙げて説明したが、本発明はこれに限定されるものではなぐメールの文 字列やアイコン等の画像に対して所定の映像効果を施す場合でも同様の効果が得 られる。 [0113] また、前述の実施の形態において、携帯端末装置を折りたたみ式の携帯電話機に 適用した例を挙げて説明したが、本発明はこれに限定されるものではなぐディスプ レイやキーボード等が一体の筐体に納められた一体型の携帯電話機でもよいし、携 帯電話以外の携帯端末装置でもよ 、。 [0112] Further, in the above-described embodiment, the configuration in which the predetermined video effect is applied to the moving image and the still image has been described as an example. However, the present invention is not limited to this. The same effect can be obtained even when a predetermined video effect is applied to an image such as an icon. [0113] Further, in the above-described embodiment, the portable terminal device has been described as an example applied to a foldable mobile phone. However, the present invention is not limited to this, and a display, a keyboard, and the like are integrated. It can be an integrated mobile phone housed in a case or a mobile terminal device other than a mobile phone.

The encoded video data is multiplexed by the CPU 64, and the multiplexed video data is stored by the video signal supply unit 61 or transmitted by the transmission unit 63 (step S103). Here, the encoded video data may be stored or transmitted without being multiplexed.
[0147] なお、ステップ S22において、表示状態が横表示状態 S92から縦表示状態 S91に 切り替わると判断された場合は、縦画像表示用処理がなされる (ステップ S104)。こ の縦画像表示用処理は、ステップ S41からステップ S48までの処理 (ステップ S 101 を含む）と、ステップ S102及びステップ S103の処理とを含む処理と同等であるので 説明を省略する。  [0147] When it is determined in step S22 that the display state is switched from the horizontal display state S92 to the vertical display state S91, a vertical image display process is performed (step S104). This vertical image display processing is the same as the processing including the processing from step S41 to step S48 (including step S101) and the processing of steps S102 and S103.
