ABSTRACT:
An apparatus for generating pictures comprising a memory device, an address generator, a vertical position detector, a register, a horizontal position counter, a processor and a state machine. Pictures shown in the display are formed based on image parameters stored in the memory device. These parameters are read from memory by controlling the address generator. The parameters read from memory are then processed by the processor before being output to the display. The vertical position detector and the horizontal position counter are provided for controlling the parameter processing. Control signals are generated in the state machine to control the apparatus. By splitting pictures into image cells and skillfully arranging corresponding parameters, colorful pictures with various layer levels are effectively shown in the display.
