ABSTRACT:
In an image processing system with an on-screen display function, a method of storing data of a row buffer in the on-screen display is to provide to minimize the capacity of the buffer by storing both character data and color data into a signal row buffer, thereby displaying a great deal of information on a monitor. Also, a row buffer control circuit for simultaneously storing characters and color data in the row buffer comprises a control data storing circuit, a column controlling part, a row controlling part, and a signal processing part.
