<p>PROBLEM TO BE SOLVED: To provide a video tape recorder(VTR) with a built-in camera for smoothly performing various kind of control to an optical system in the case of switching from a still picture photographing mode to a moving image photographing mode concerning the VTR with a built-in camera having a memory for holding still pictures on the preceding stage of signal processing means. SOLUTION: When an operating part 61 is operated and there is a still photographing instruction from a system microcomputer 41 to a camera microcomputer 71, a zoom position is moved to a wide end and focal depth is made into bottom by stopping an automatic focusing function and a diaphragm correcting function to be executed by the camera microcomputer 71 at the time of moving image pickup and controlling a zoom driving function. At the same time, a focus position is moved to a far side by controlling a focus driving function, and an iris is controlled only by an analog signal from a correlative double sampling element(CDS) 22.</p> |
