摘要： A plurality of CCD image pickup devices are provided. When the multiplex exposure is executed, the exposure timings of the plurality of image pickup devices are set to different timings. The output signals of the plurality of image pickup devices of different timings are synchronized and synthesized, thereby forming a multiplexed signal.

摘要： A video camera system has a movable focusing lens which is automatically focused to form a sharp subject image on a CCD. The CCD generates a video signal based on light from a subject transmitted through the movable focusing lens. Contrast data are produced from smaller and larger image frames in a field on the CCD based on the generated video signal. The movable focusing lens is controlled on the basis of the contrast data in order to maximize the contrast data simultaneously within the smaller and larger image frames.

摘要： A video camera system has a movable focusing lens which is automatically focused to form a sharp subject image on a CCD. The CCD generates a video signal based on light transmitted from a subject through the movable focusing lens. Maximum contrast data are produced from each horizontal scanning line in an image frame in a field on the CCD, and are then integrated by an integrator. The movable focusing lens is controlled in order to maximize the integrated contrast data.
