Abstract:
An image processing device comprising:a compressor for compressing a plurality of sets of image data received from a data source and for outputting a plurality of sets of thus compressed image data; a controller for changing a compression ratio of the compressor in accordance with image data attributes, wherein at least one of said image data attributes is selected from a group consisting of a magnification ratio and a size of an image; a buffer section including a memory for storing at least one set of compressed image data, said buffer section being capable of synchronizing transfer of the plurality of sets of compressed image data including the at least one set of compressed image data stored in said memory, said memory including N sets of FIFO (First-In First-Out) memories for storing the at least one set of compressed image data, wherein N is a positive integer; and an image processing section for receiving the plurality of sets of compressed image data synchronized by said buffer section, and for receiving a set of image data directly from said data source, said image processing section including: an expander for expanding the plurality of sets of compressed image data; and a correction circuit for refereeing the resulting plurality of sets of expanded image data and the set of image data which is directly received from the data source, said image processing section being capable of executing a predetermined process on the plurality of sets of expanded image data and on the set of image data which is directly received from the data source.
