ABSTRACT:
In the conventional image memory diagnosis, diagnosis data is written in the image memory for a comparison between the data read out of the image memory and the diagnosis data. All the address and control signals for the image memory are output by the system. By contrast, according to the invention, the display control signal output by the CRT controller is converted into address and control signals for the image memory, thus not only increasing the process speed but also reducing the system load.
