Abstract
A display control apparatus for a display device capable of performing updating of a display state for a display element subjected to a change in display includes a display data memory for storing display data, a display controller capable of sequentially reading out the display data stored in the memory and transferring the readout display data to the display device at a predetermined period and capable of performing a partial rewrite operation of the display data stored in the memory, and a rewrite detector for detecting an address for accessing the display data memory to cause the display controller to perform the partial rewrite operation. In addition, a transfer permitting unit reads the address detected by the rewrite detector and permits transfer of only the display data of the read address to the display controller.
