This invention relates to a video camera with a still camera equipped with both a video camera device tE and a still camera.

BACKGROUND OF THE INVENTION While filming with a television camera or video camera with videotape recording capabilities, there has been a desire to record still photographs of specific scenes. In the past, for example, people carried both a silver halide still camera and a video camera.
If there was a scene that I wanted to shoot with a still camera while shooting with a video camera, I would stop shooting with the video camera and shoot with the still camera. In such a situation, you would have to carry two devices, and you would have to stop shooting with a video camera when shooting with a still camera.
This has led to various problems, including the risk of missing important photo opportunities.

Therefore, in order to solve this problem, it is possible to combine a still camera and a video camera into one device, and then operate the still camera to take still pictures without interrupting the video camera. A video camera with still camera is required.

Therefore, for example, it is desirable that still cameras and video cameras have an autofocus function.

By the way, for example, when a still camera and a video camera are detachably attached, it is undesirable to provide a power source for driving the autofocus mechanism in both the still camera and the video camera because it increases the weight of the device. .

Further, the autofocus mechanism cannot be activated when normal power cannot be supplied from the power supply, but there are times when it is desired to take a picture even in such a case.

In view of these demands, the present invention enables video and still photography to be performed simultaneously, and also uses a common power source to drive the autofocus function for both video and still photography, while also removing power from the power source. To provide a video camera with a still camera capable of photographing even when the supply is unavailable.

In addition to the signal from the AF sensor 57, the EE sensor 5
When adjusting the focal length using a signal set by the still camera system controller 41 based on the signal from the camera 8, the motor 46 is driven to fix the focal length. In other words, when the subject is large and the aperture amount of the aperture 3B set by the still camera system controller 41 is large, the depth of field is large, so the focal length may be fixed at a constant value. Therefore, the rotation of the motor 46 is controlled so that the 48a-2 surface of the cam 48 presses the bottle 50.

In addition, if the power necessary to drive the motor 46 is no longer supplied from the power source 70, such as when the amount of stored electricity in the power source 70 decreases, the motor 46 is set in advance so that the surface 48a-2 of the cam 48 presses the bottle 50. 46 to set a fixed focus. As a result, after power is no longer supplied from the power source 70, still photography is performed with a fixed focus.

After adjusting the opening amount of the aperture 36 and the position of the lens 28 in this manner, the exposure control section 40 opens and closes the shutter 30, and still photography is performed.

After opening and closing the shutter 30, a control command signal is output from the still camera system controller 41 to the film winding drive circuit 38, which causes the film winding drive circuit 38 to rotate the sprocket 38 and roll the roll film 31 for one frame. Roll up.
