ABSTRACT:
An image displaying apparatus includes a first line buffer for storing image data of an image to be displayed, a SRAM which is provided downstream of the first line buffer and in which the image data stored in the first line buffer are written, a second line buffer provided downstream of the SRAM for storing the image data read from the SRAM, a CRT provided downstream of the second line buffer, and a control circuit for controlling the operation of the first line buffer, the SRAM and the second line buffer so that time contention between write-in operation of the image data into the SRAM and read-out operation of the image data from the SRAM can be prevented, the memory capacity of the SRAM being greater than those of the first line buffer and the second line buffer. According to the thus constituted image displaying apparatus, it is possible to display images based on great quantity of image data at low cost.
