Abstract

A CCD converts an optical image of an object formed on its image sensing surface into electrical charges, and sequentially outputs the electrical charges of all of the light receiving pixels in one scanning operation in non-interlaced form. The outputs from the CCD are converted to the digital image signals by an analog-digital converter. A camera signal processing unit processes the digital image signals, thereby generating two streams of signals; one is digital video signals SV1 which are standard digital video signals in interlaced form, and the other is signals SV2 which are not outputted as the digital video signals SV1 out of the digital image signals of all of the light receiving pixels. These two streams of signals, SV1 and SV2, are processed differently depending upon a mode selected by a switch.

Claims
