御装置。 In a camera control device equipped with an aperture encoder that converts the amount of change in the aperture into an electrical signal using a photo sensor, the photo sensor is activated only during the release operation, depending on the state of the signal that determines whether or not the release operation is in progress. A camera control device that is provided with a power regulation means that allows power to be supplied to the light emitting unit of the camera.
