A display controller is provided which can control the display of a fast moving image with higher quality in an active matrix display apparatus DD. When the display pattern of an image is controlled in a display apparatus DD constituted of a plurality of pixels S arranged in a matrix form, the pixel including a light-emitting device, an image is displayed by driving the pixels S only for predetermined illuminating period shorter than a vertical synchronizing period.

Display controller, display system, and display controlling method

A graphics decoder which stores color number data of each pixel of the display screen, which is acquired from a subcode signal, sequentially reads out the color number data to produce a graphics RGB signal referring to a color look-up table, and supplies the graphics RGB signal to a CRT display. When a graphics command acquired from the subcode signal is a screen-scroll command, scroll data is obtained from pointer data included in that scroll command, and that scroll data is output at a timing synchronous with a horizontal sync signal or vertical sync signal to set the read address of the display memory. When the graphics command is a color look-up table write command, the color look-up table is updated at a timing synchronous with the first horizontal sync signal or vertical sync signal after the generation of that write command.
