Abstract
A color image signal input from a CCD or the like is processed to generate a color image signal containing a color subimage portion or a monochrome image signal containing a monochrome subimage portion and to record the image signals directly or after the image signals are JPEG compressed. For JPEG color recording, a color image signal supplied from a CCD and A/D converter is input to a selector, and to a 10/16 converting circuit and a first FIFO, and thereafter a color image and its color subimage are generated by a video processing circuit and compressed by a JPEG circuit, and output from a second FIFO and bus I/F to be recorded. For JPEG monochrome recording, an input color image signal is supplied to the 10/16 converting circuit and clamp circuit, multiplied at the first FIFO by a predetermined coefficient to generate a monochrome image containing a subimage. For RAW color or monochrome recording, JPEG compression is not performed.
