Abstract

Abstract A series of arrangements from a CCD sensor to an input masking unit output image data obtained by reading an original image. A JPEG-I/F receives JPEG or MPEG image data from an ATM network. The input JPEG or MPEG data is temporarily stored in a page memory, and is read out from the page memory in synchronism with the image formation timings. The readout data is decoded by a JPEG (or MPEG) expansion unit. A bus selector selects the image data output from the input masking unit or the JPEG (or MPEG) expansion unit, and the selected image data is supplied to a compression unit via a color space conversion unit and a zooming unit. The memory size can be reduced using a common coding unit and high-quality image data can be output independently of whether or not input image data is coded.
