ABSTRACT:
A camara control device continues a pre-winding or a first frame setting when a pre-winding or a first frame setting is stopped in the middle because a battery of the camera is taken out or because of exhaustion of the battery and after that another battery is loaded. The camera control device writes a pre-wind signal to an electrically rewritable non-volatile memory E.sup.2 PROM when a pre-winding is started and erases the pre-wind signal in the E.sup.2 PROM when the pre-winding is finished, and writes a first frame set signal to the E.sup.2 PROM when a first frame setting is started and erases the first frame set signal in the E.sup.2 PROM when the first frame setting is finished. If the pre-winding or the first frame setting is stopped in the middle, the pre-wind signal or the first frame set signal in the E.sup.2 PROM is not erased. The camera control device, responsive to loading of the battery to the camera, continues the pre-winding or the first frame setting when the pre-wind signal or the first frame set signal is left in the E.sup.2 PROM.
