    摘要: A display control apparatus for a display device, capable of updating a display state for a display element subjected to a change in display updating, includes a display data memory for storing display data, and 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. A rewrite detector detects an address for accessing the display data memory to cause the display controller to perform the partial rewrite operation, a specific pattern rewrite detector detects an address of display data subjected to a rewrite operation of the specific pattern and stored in the display data memory, and a rewrite address generator preferentially transfers the address detected by the specific pattern rewrite detector over the address detected by the rewrite detector, reads out the display data from the display data memory at the transferred address, and transfers the readout data to the display device.

    摘要: It can be determined without visually observing the display screen of a display device whether image conversion processing in a conversion circuit for outputting image data to the display device is being performed normally. The conversion circuit extracts data at a position designated from a host apparatus from image data output to the display device, and outputs the extracted data to the host apparatus. In the host apparatus, image data obtained upon normal conversion in the conversion circuit is prepared in advance, and this image data is collated with the data sent from the conversion circuit to determine whether the operation of the conversion circuit is normal.
