ABSTRACT:
A color image recording apparatus capable of reducing a memory area for storing input image data by storing the image data after converting them into indexes with a bit length shorter than that of the image data. It is decided whether or not color information just read has already been registered in a color information holding area, and if not, the color information is registered. Subsequently, it is decided whether the number of registrations of the color information exceeds an upper limit of registration, and if it exceeds, an error processing is carried out. In this case, neither the storing nor the drawing of the image data is performed. If the number does not exceed, an index attached to the color information data at the registration is stored in an image data holding area as pixel data of the image data.
