Abstract
An image processing apparatus designed to interface with different monitors which processes image data read from a video random access memory (VRAM) so as to display an image corresponding to the image data on a screen of a display unit under a control of a central processing unit (CPU). The image processing apparatus at least provides a plurality of registers and a memory for storing several kinds of reference data for several kinds of predetermined modes. When one mode is selected from the predetermined modes, one of a color display and a monochromatic display is selectively performed on a screen of one of a color monitor and a monochromatic monitor or a screen of one of moniters each having different standard. The reference data corresponding to the selected mode are read from the memory and stored in the registers. When the selected mode is changed, reference data stored in requisite registers selected by newly selected mode are automatically rewritten by the reference data selected by the newly selected mode without exchanging programs of the CPU.
