To realize an effective still image continuous photographing function.

A signal from an image pickup means 1 provided with a solid state image pickup device and a color difference sequential type color filter array is supplied to a camera signal processing IC 100 through a front end circuit 2 and then supplied to a camera signal processing block 4 through the high speed continuous photographing contact (a) of a change-over switch 3. On the other hand, the signal from the circuit 2 is written in a random access memory(RAM) 6 through a memory controller 5 and the signal read out from the RAM 6 is supplied to the normal continuous photographing contact (b) of the switch 3. A luminance signal (Y) and macro signals (Cr, Cb) formed by a camera signal processing block 4 are stored in a RAM 8 through a pixel conversion block 7 and the signal from the block 7 is extracted to the external through an IC interface block 9. A synchronizing signal from a timing generation circuit 10 is extracted to the external.
