ABSTRACT:
An imaging signal obtained from CCD is supplied to the pre-processing circuit to form the pre-processing signal consisting of a luminance signal and a color signal and the pre-processing signal is supplied in turn to the post-processing circuit to form the post-processing signal to be outputted to the external circuit or to be recorded. The circuits from CCD to pre-processing circuit are driven by the first clock CKH or the second clock which is slower than the first clock, while the post-processing circuit is driven by the first clock. A clock exchange circuit is provided between the pre-processing circuit and the post-processing circuit, and when the circuits up to the pre-processing circuit are driven by the second clock, the clock exchange circuit is operated to supply the pre-processing signal exchanged to the first clock from the second clock is supplied to the post-processing circuit. Thereby, the post-processing circuit can used in common.
