Abstract
Abstract A camera is provided with silver halide film, a CCD for shooting, a display device, a magnetic tape and a flash device, and shooting by the silver halide film is performed while shooting by the CCD is being performed. Pictures taken by the CCD are displayed in the display device and recorded on the magnetic tape. When shooting is accompanied with a flash, exposure of the silver halide film is synchronized with a predetermined cycle of photoelectric conversion of the CCD, or the photoelectric conversion of the CCD is synchronized with the exposure of the silver halide film by varying the cycle. The picture taken by the CCD with a flash is displayed for a while just after shooting as a release-view, and can be displayed later as an after-view.
