Abstract
In an image processing apparatus, a compression processor compresses a color image data, a storage device stores the compressed data, and an expansion processor expands the data read from the storage device. A first background controller controls background of the color image data not yet compressed by the compression processor, while a second background controller controls background of the image data expanded by the expansion processor. A controller activates either the first background controller or the second background controller.
