Description

本発明は傾きセンサを備えた撮像装置に関するものである。   The present invention relates to an imaging apparatus provided with a tilt sensor.

従来の撮像装置の水平面に対する傾きを撮影者に知らせる手法としては表示部近傍に水準器を取り付ける、あるいは水準器の動作を擬似的に撮像装置本体に取り付けられた表示部に表示するものがある(例えば特許文献1参照。)。また、パイロットランプと表示部に移動表示体を追加することによって撮影者に傾きを知らせるものもある(例えば特許文献2。)。

しかしながら、上記従来例では撮像装置本体に部品を追加することによってコストが増大してしまう、もしくは表示部分に新たな表示体を追加することによって表示可能面積が減り、撮影対象が見えにくくなってしまう場合があった。   However, in the above-described conventional example, the cost increases by adding parts to the image pickup apparatus main body, or the displayable area decreases by adding a new display body to the display portion, making it difficult to see the photographing target. There was a case.

本出願に係る発明の目的は部品や表示を追加することなく、既存の表示体を用いて撮影中に撮影者に撮像装置の傾きを知らせ、撮像装置を水平に保持するのを促すことにある。   An object of the present invention is to inform the photographer of the inclination of the imaging device during shooting using an existing display body without adding parts or displays, and to encourage the imaging device to be held horizontally. .

本発明は撮像装置において、水平に対して傾きを検出する傾き検出手段と、前記傾きから撮像装置の傾き角度を算出する演算手段と、撮像装置の状態データを取得するデータ取得手段と、前記状態データを表示する表示手段と、前記状態データの表示を回転移動する演算手段を具備し、
撮像装置の前記状態データの表示を前記傾き角度と逆方向に回転移動し、常に水平と平行になるように表示することを特徴とする。
The present invention relates to an imaging apparatus, an inclination detection unit that detects an inclination with respect to the horizontal, a calculation unit that calculates an inclination angle of the imaging device from the inclination, a data acquisition unit that acquires state data of the imaging device, and the state Display means for displaying data, and calculation means for rotating the display of the state data,
The state data display of the image pickup apparatus is rotated and moved in the direction opposite to the tilt angle, and is always displayed in parallel with the horizontal direction.

以上説明したように、本発明によれば、撮像装置本体が傾いた場合でも撮像装置の状態を示す表示が常に水平に保たれるため、部品や表示を追加することなく撮影者が水平を確認でき、傾きを修正することが可能である。その結果、意図しない傾きを持った画像が撮影され続けることを防ぐことができる。   As described above, according to the present invention, since the display indicating the state of the imaging apparatus is always kept horizontal even when the imaging apparatus main body is tilted, the photographer confirms the level without adding parts or displays. It is possible to correct the inclination. As a result, it is possible to prevent an image having an unintended inclination from being continuously taken.

次に、本発明の詳細を実施例の記述に従って説明する。   Next, details of the present invention will be described in accordance with the description of the embodiments.

以下、本発明の実施例について詳細に説明する。   Examples of the present invention will be described in detail below.

図1は本発明の特徴を最もよく表す構成例である。同図において1は外部の光を受けてアナログデータに変換する撮像素子、2はアナログデータをデジタルデータに変換するアナログ・デジタルコンバータ(ADC)、3はデータを一時保管するためのメモリ、4は画像データを処理する画像処理回路、5は画像データと撮像装置の状態を表示する表示部、6は撮像装置の傾きを検出するための傾きセンサ、7は検出された傾きを水平に対する傾き角度に変換する演算回路である。外部からの光は1の撮像素子によってアナログ信号の画像データに変換され、2のADCに入力された後、デジタルデータに変換され、4の画像処理回路に入力される。また、撮像装置の傾きは6の傾きセンサによって検出され、7の演算回路によってレンズを通して入射する光軸周りの成分に分解され、水平に対する傾き角度として4の画像処理回路に入力される。4の画像処理回路に入力された画像データと傾き角度、図外から取得した撮像装置本体の状態データは3のメモリ上に一旦保存され、4の画像処理回路で演算後に合成されてから、5の表示部に出力される。5の表示部には画像データと演算された撮像装置本体の状態が表示される。   FIG. 1 is a configuration example that best represents the features of the present invention. In the figure, 1 is an image sensor that receives external light and converts it into analog data, 2 is an analog-digital converter (ADC) that converts analog data into digital data, 3 is a memory for temporarily storing data, 4 An image processing circuit for processing image data, 5 is a display unit for displaying the image data and the state of the imaging device, 6 is a tilt sensor for detecting the tilt of the imaging device, and 7 is a tilt angle with respect to the horizontal. An arithmetic circuit to convert. Light from the outside is converted into image data of an analog signal by one image sensor, is input to two ADCs, is converted to digital data, and is input to four image processing circuits. Further, the tilt of the image pickup device is detected by a tilt sensor of 6, and is decomposed into components around the optical axis incident through the lens by an arithmetic circuit of 7, and input to the image processing circuit of 4 as a tilt angle with respect to the horizontal. The image data and the tilt angle input to the image processing circuit 4 and the state data of the imaging apparatus main body acquired from the outside of the figure are temporarily stored in the memory 3, synthesized after calculation by the image processing circuit 4, and then 5 Is output to the display. The display unit 5 displays the image data and the calculated state of the imaging apparatus main body.

図2に示すような図形を撮影対象とした場合、撮像装置が水平に保たれていれば、撮影中または撮影待機中には表示部に図3の四角枠内のような画像が表示される。枠内の英数字は撮像装置の状態を表すもので、8の表示はレンズが望遠端と広角端の間のどの位置にあるか、9の表示は撮影時間、10の表示は撮影画質を示したものである。実施例の中ではこれらの状態データを用いているが、撮影中または撮影待機中に撮像装置の状態を表す表示であればどんな形であっても構わない。右側にある2つの矢印は座標軸を表しており、11の矢印は水平面と垂直、12の矢印は水平面と平行の向きを示している。これらの矢印は模式的に用いたもので表示部に表示されることはない。撮像装置を水平からわずかに傾けた場合、本発明を実施しない時は表示部には図4の四角枠内のような画像が表示され、撮像装置の状態を示す表示と表示部の相対的な位置関係や角度は変化することはない。それに対して本発明を実施した時は図5の四角枠内のように撮像装置の状態を示す表示を、撮像装置本体が傾けられることによって下側になる端を中心に、常に水平を保つように回転移動させる。撮像装置の状態を示す表示は常に水平を保つため、撮影者は撮像装置の状態を確認する際に同時に撮像装置の傾きを認識することができ、容易に傾きを補正することができる。また、既存の表示を用いているため、部品や表示を追加する必要がない。図6に示すように撮像装置の状態を示す表示をいくつかに区切り、それぞれの表示を中心に回転移動させてもよい。この手法では撮像装置の状態を示す表示と表示部の相対的な位置関係は大きく変化することなく、撮像装置の状態を示す表示が撮像対象と重なって見えにくくなることはなくなる。   When a figure as shown in FIG. 2 is taken as an object to be photographed, if the image pickup apparatus is kept horizontal, an image as shown in the square frame of FIG. 3 is displayed on the display unit during photographing or during photographing standby. . Alphanumeric characters in the frame represent the state of the imaging device. 8 indicates the position of the lens between the telephoto end and the wide-angle end, 9 indicates the shooting time, and 10 indicates the image quality. It is a thing. In the embodiment, these state data are used, but any form may be used as long as the display indicates the state of the image pickup apparatus during photographing or standby for photographing. Two arrows on the right side represent coordinate axes, 11 arrows indicate a direction perpendicular to the horizontal plane, and 12 arrows indicate a direction parallel to the horizontal plane. These arrows are schematically used and are not displayed on the display unit. When the image pickup device is slightly tilted from the horizontal, when the present invention is not implemented, an image as shown in the square frame of FIG. 4 is displayed on the display unit, and the display showing the state of the image pickup device and the display unit relative to each other The positional relationship and angle do not change. On the other hand, when the present invention is carried out, the display indicating the state of the imaging device as in the rectangular frame of FIG. Move to rotate. Since the display indicating the state of the imaging apparatus is always kept horizontal, the photographer can recognize the inclination of the imaging apparatus at the same time when checking the state of the imaging apparatus, and can easily correct the inclination. Moreover, since the existing display is used, it is not necessary to add a part or a display. As shown in FIG. 6, the display indicating the state of the imaging apparatus may be divided into some parts and rotated around each display. In this method, the relative positional relationship between the display indicating the state of the imaging apparatus and the display unit does not change significantly, and the display indicating the state of the imaging apparatus does not overlap with the imaging target and become difficult to see.
