Abstract
A raster/block converting section converts an input raster image signal into a block scan signal. A compressing/coding section selectively compresses and codes one of the block scan signal, converted by the raster/block converting section, and a differential signal. An expanding/decoding section expands and decodes the block scan signal compressed and coded by the compressing/coding section. A block/raster converting section converts the block scan signal, expanded and decoded by the expanding/decoding section, into a raster signal. A filter section filters the raster signal, converted by the block/raster converting section, to remove deformation at a boundary between blocks. A differentiating section substantially obtains a difference between the raster signal filtered by the filter section and the input raster image signal and supplies the difference as the differential signal to the compressing/coding section.
