An optical apparatus according to another aspect of the present invention is an optical apparatus capable of capturing a still image and a moving image, and switching between a still image mode for capturing the still image and a moving image mode for capturing the movie. A diaphragm, drive means for driving the diaphragm at a first speed or a second speed higher than the first speed, and control means for controlling the drive means, the control means comprising: When the optical device is switched from the still image mode to the moving image mode, the diaphragm is driven at the second speed, and during recording of a moving image, the diaphragm is driven at the first speed. To do.
A control method according to another aspect of the present invention is a method for controlling an optical apparatus capable of shooting a moving image and having an aperture, and during recording of the moving image, the aperture is driven at a first speed, When moving image shooting is not performed, the diaphragm is driven at a second speed that is faster than the first speed.
According to another aspect of the present invention, there is provided a control method having an aperture, capable of capturing a still image and a moving image, and switching between a still image mode for capturing the still image and a moving image mode for capturing the moving image. When the moving image is recorded in the moving image mode, the aperture is driven at the first speed and the still image mode is switched to the moving image mode. The diaphragm is driven at a high second speed.
本発明によれば、動画撮影の非記録時での絞りの駆動速度を動画記録中の絞りの駆動速度よりも高速にした光学機器およびその制御方法を提供することができる。 ADVANTAGE OF THE INVENTION According to this invention, the optical device which made the drive speed of the aperture stop at the time of non-recording of moving image photography higher than the drive speed of the aperture stop during moving image recording, and its control method can be provided.
以上のようにして、絞りを低速度で駆動させる必要がある動画撮影の準備段階においては、絞りを高速度で駆動させることにより素早く動画撮影可能な状態にできる。また、動画記録が終了した際にも高速度で絞りを開放状態まで駆動することにより、素早く静止画を撮影可能な状態にすることができる。つまり、動画モードにおいて動画記録を行っていないとき（非記録時）には、絞りを高速度で駆動させることができる。このため、例えば静止画撮影と動画撮影の切り替えがスムーズに行われ、素早く撮影可能な状態にすることが可能となる。上記実施例によれば、動画撮影準備段階での絞りの駆動速度を動画記録中の絞りの駆動速度よりも高速にした光学機器およびその制御方法を提供することができる。 As described above, at the preparation stage of moving image shooting in which it is necessary to drive the aperture at a low speed, the moving image can be quickly captured by driving the aperture at a high speed. Further, even when the moving image recording is completed, the still image can be quickly captured by driving the aperture to the open state at a high speed. That is, when moving image recording is not performed in the moving image mode (when not recording), the aperture can be driven at a high speed. For this reason, for example, switching between still image shooting and moving image shooting is performed smoothly, and a state in which shooting can be performed quickly becomes possible. According to the above-described embodiment, it is possible to provide an optical apparatus and a control method therefor in which the aperture driving speed in the moving image shooting preparation stage is higher than the aperture driving speed during moving image recording.
