Description

【０００１】
【発明の属する技術分野】
本発明は、テレビレンズのズーム、フォーカス等の位置を記憶、読み出すためのプリセット機能を有する撮影装置に関するものである。
【０００２】
【従来の技術】
図５は従来例のテレビレンズ１のズーム、フォーカス等の位置を記憶、読み出して撮影を行う撮影装置の斜視図、図６はズーム操作手段の拡大斜視図を示している。テレビレンズ１及びテレビカメラ２は雲台３上に載置され、テレビカメラ２にはフォーカス操作手段４が取り付けられ、雲台３にはズーム操作手段５が取り付けられている。ズーム操作手段５の先端には複数のプリセットスイッチ６を有するプリセットボックス７が設けられている。プリセットスイッチ６の出力は制御手段８に接続され、この制御手段８の出力はテレビレンズ１、記憶手段９にそれぞれ接続されている。
【０００３】
撮影に際し所望の映像を得るために、先ず操作者は雲台３のパンニング角、チルティング角を決め、フォーカス操作手段４により被写体にフォーカスを合わせ、ズーム操作手段５により画角を決定する。次に、ズーム操作手段５のプリセットボックス７にあるプリセットスイッチ６を操作して、制御手段８によりテレビレンズ１のズーム、フォーカス等の位置を予め記憶手段９に記憶する。なお、複数のプリセットが必要な場合はプリセットスイッチ６を選択して使用する。
【０００４】
操作者が所望の映像を再現するためには、雲台３のパンニング角、チルティング角を被写体に向け、そのパンニング角、チルティング角に対応するテレビレンズ１のズーム、フォーカス等の位置を、プリセットスイッチ６を選択することにより再現する。なお、ズーム、フォーカスの両方をプリセットしているが、ズーム又はフォーカスのみのプリセット機能を有する撮影装置もある。
【０００５】
【発明が解決しようとする課題】
しかしながら上述の従来例においては、プリセットスイッチ６を搭載するためのスペースの関係上、プリセット数が限定されてしまい、例えばテンキーを用いてプリセット等を操作することによってプリセット数の増加を図った場合には、操作者は雲台３のパンニング角、チルティング角に対応した全てのプリセット番号を記憶している必要があり、極めて煩雑となるために誤操作の原因となる。

【００１０】
【発明の実施の形態】
本発明を図１〜図４に図示の実施例に基づいて詳細に説明する。
図１は第１の実施例の撮影装置の斜視図を示し、テレビレンズ１０及びテレビカメラ１１は所望のパンニング角、チルティング角を与える雲台１２に搭載され、テレビレンズ１０にはフォーカス操作手段１３が取り付けられ、このフォーカス操作手段１３の出力は制御手段１７に接続され、また雲台１２から延在する腕の先にはズーム操作手段１４が取り付けられ、このズーム操作手段１４の出力は制御手段１７に接続されている。雲台１２の下部にはパンニング角検出器１５が固定され、側部にはチルティング角検出器１６が固定されている。また、制御手段１７の出力はテレビレンズ１０、パンニング角検出器１５、チルティング角検出器１６、記憶手段１８にそれぞれ接続されている。
【００１１】
上述の構成において所望の映像を得るために、操作者は雲台１２のパンニング角、チルティング角を決め、フォーカス操作装置１３により被写体にフォーカスを合わせ、ズーム操作手段１４により画角を決定する。次に、ズーム操作手段１４の図示しないスイッチにより制御手段１７に指令を与えると、制御手段１７は雲台１２のパンニング角検出器１５、チルティング角検出器１６の角度情報及びテレビレンズ１０のズーム、フォーカスの位置情報を記憶手段１８に記憶してプリセット状態にする。
【００１２】
図２、図３はプリセット状態の説明図を示し、P1、P2、P3の３個所を撮影できるようにプリセットされている。操作者がプリセット位置から所定の範囲（PX，PY）内にパンニング角、チルティング角を設定した場合に、ズーム、フォーカス位置が自動的に再現される。また、現在のパンニング角、チルティング角の位置Ｏから最も近いプリセット位置、例えば図３に示す距離Ｌ３のP3の位置のズーム、フォーカス状態を自動的に再現するようにしてもよい。このようにして、複数のプリセットスイッチを選択的に操作することなく、自動的にズーム、フォーカス位置の記憶、再現が可能となる。
【００１３】
なお、ズーム、フォーカスの記憶を指令するスイッチをズーム操作手段１４ではなく、テレビカメラ１１やフォーカス操作手段１３に設けてもよい。また、ズーム、フォーカス位置は、図２の場合ではパンニング角、チルティング角がプリセット位置から所定の範囲（PX，PY）にあるときに、スイッチ操作により再現するようにし、図３の場合にはスイッチを操作したときに、最も近い距離Ｌ３のプリセット位置P3のズーム、フォーカス位置を再現するようにしてもよい。
【００１４】
図４は第２の実施例の斜視図を示し、テレビカメラ１０の上面にパンニング角度内の角加速度を検出する加速度センサ２１が取り付けられ、側面にチルティング角面内の角加速度を検出する加速度センサ２２が取り付けられており、加速度センサ２１、２２の出力はそれぞれ制御手段１７に接続されている。その他の構成は第１の実施例と同様で同じ符号は同じ部材を表している。
【００１５】
加速度センサ２１、２２の情報を基に、テレビレンズ１０及びテレビカメラ１１のパンニング角、チルティング角の変位を制御手段１７で算出して、パンニング、チルティングの角度位置を得る。このようにすれば、角検出器１５、１６を有しない一般の雲台１２でも、第１の実施例と同様の効果を得ることができる。なお、加速度センサ２１、２２はテレビレンズ１０ではなく、テレビカメラ１１側に設けてもよい。
【００１６】
【発明の効果】
以上説明したように本発明に係る撮影装置は、テレビレンズ及びテレビカメラのパンニング角、チルティング角に対応してテレビレンズのズーム又はフォーカスの状態を記憶、再現することにより、プリセットスイッチを操作することなく、レンズのフォーカス、ズーム位置を記憶、読み出しできるので、プリセット数がスイッチの搭載スペースにより制限されることがなく、プリセット数の増加が可能となり、操作者はパンニング角、チルティング角に対応したプリセット番号を記憶する必要がない。また、撮影時のズーム、フォーカス操作の軽減とプリセットスイッチの誤操作を防止し、正確な画作りが可能となる。
【００１７】
また、本発明に係る撮影装置は、パンニング角、チルティング角回りの角加速度を検出して角度変位を算出し、レンズ又はカメラのパンニング角、チルティング角による位置情報に対応してレンズのズーム位置情報を記憶し、読み出した位置情報に基づいてズーム又はフォーカスを再現することにより、従来の雲台を用いてプリセットスイッチを操作することなく、レンズのフォーカス、ズーム位置を記憶、読み出しできるので、プリセット数がスイッチの搭載スペースにより制限されることがなく、プリセット数の増加が可能となり、操作者はパンニング角、チルティング角に対応したプリセット番号を記憶する必要がない。また、撮影時のズーム、フォーカス操作の軽減とプリセットスイッチの誤操作を防止し、正確な画作りができる。

DETAILED DESCRIPTION OF THE INVENTION
The present invention will be described in detail based on the embodiment shown in FIGS.
FIG. 1 is a perspective view of the photographing apparatus of the first embodiment. A television lens 10 and a television camera 11 are mounted on a pan head 12 that gives a desired panning angle and tilting angle. 13 is attached, and the output of the focus operation means 13 is connected to the control means 17, and the zoom operation means 14 is attached to the tip of the arm extending from the camera platform 12, and the output of the zoom operation means 14 is controlled. Connected to means 17. A panning angle detector 15 is fixed to the lower part of the pan head 12, and a tilting angle detector 16 is fixed to the side. The output of the control means 17 is connected to the TV lens 10, the panning angle detector 15, the tilting angle detector 16, and the storage means 18, respectively.
[0011]
In order to obtain a desired image in the above-described configuration, the operator determines the panning angle and tilting angle of the camera platform 12, focuses the subject with the focus operation device 13, and determines the angle of view with the zoom operation means 14. Next, when a command is given to the control unit 17 by a switch (not shown) of the zoom operation unit 14, the control unit 17 performs angle information on the panning angle detector 15 and tilting angle detector 16 of the camera platform 12 and the zoom of the TV lens 10. The focus position information is stored in the storage means 18 to be in a preset state.
[0012]
2 and 3 are explanatory diagrams of the preset state, which are preset so that three positions P1, P2, and P3 can be photographed. When the operator sets the panning angle and tilting angle within a predetermined range (PX, PY) from the preset position, the zoom and focus positions are automatically reproduced. Further, the current panning angle, nearest to the preset position from the position O of tilting angle, for example, the P3 position of the zoom of a distance L 3 shown in FIG. 3, may be automatically reproduced the focus state. In this way, it is possible to automatically store zoom and focus position and reproduce without selectively operating a plurality of preset switches.
[0013]
It should be noted that a switch for instructing zoom and focus storage may be provided in the television camera 11 or the focus operation means 13 instead of the zoom operation means 14. The zoom and focus positions are reproduced by switch operation when the panning angle and tilting angle are within a predetermined range (PX, PY) from the preset position in the case of FIG. 2, and in the case of FIG. When the switch is operated, the zoom and focus positions of the preset position P3 at the closest distance L3 may be reproduced.
[0014]
FIG. 4 shows a perspective view of the second embodiment, in which an acceleration sensor 21 for detecting angular acceleration within a panning angle is attached to the upper surface of the television camera 10 and acceleration for detecting angular acceleration within a tilting angular plane is provided on the side surface. A sensor 22 is attached, and the outputs of the acceleration sensors 21 and 22 are connected to the control means 17, respectively. Other configurations are the same as those of the first embodiment, and the same reference numerals denote the same members.
[0015]
Based on the information of the acceleration sensors 21 and 22, the panning angle and tilting angle displacement of the TV lens 10 and the TV camera 11 are calculated by the control means 17, and the panning and tilting angular positions are obtained. In this way, even with a general pan head 12 that does not have the angle detectors 15 and 16, the same effect as in the first embodiment can be obtained. The acceleration sensors 21 and 22 may be provided on the TV camera 11 side instead of the TV lens 10.
[0016]
【The invention's effect】
As described above, the photographing apparatus according to the present invention operates the preset switch by storing and reproducing the zoom or focus state of the TV lens corresponding to the panning angle and tilting angle of the TV lens and the TV camera. The focus and zoom position of the lens can be stored and read without any restriction, so the number of presets is not limited by the switch mounting space, and the number of presets can be increased, allowing the operator to handle panning and tilting angles. There is no need to memorize the preset number. In addition, zooming and focusing operations during shooting can be reduced, and erroneous operation of the preset switch can be prevented, thereby making it possible to create an accurate image.
[0017]
In addition, the imaging apparatus according to the present invention detects angular acceleration around the panning angle and tilting angle to calculate the angular displacement, and zooms the lens corresponding to the positional information based on the panning angle and tilting angle of the lens or camera. By storing the position information and reproducing the zoom or focus based on the read position information, the focus and zoom position of the lens can be stored and read without operating the preset switch using a conventional pan head. The number of presets is not limited by the mounting space of the switch, the number of presets can be increased, and the operator does not need to store preset numbers corresponding to the panning angle and tilting angle. In addition, zoom and focus operations during shooting can be reduced, and incorrect operation of the preset switch can be prevented to create accurate images.
