ABSTRACT:
A display apparatus consists of a display memory (VRAM), a data modifier circuit and a display unit at least. The display unit, such as a CRT display unit, has a plurality of display dots which include red, green and blue color dots. The display memory must be cleaned at a primary stage and thereafter a plurality of display codes corresponding to only display dots on the outlines of the color image must be written into the display memory. The display codes are converted into display data which indicate red, green and blue color components. The display codes are successively read out from the display memory and supplied to the data modifier circuit wherein the display data are modified so as to compensate the display data which are not written into the display memory. The display unit displays the image corresponding to the modified display data on the screen thereof.
