Abstract
Techniques for adaptively accessing image data in a data memory space are disclosed. According to one aspect of the present invention, a data transfer bandwidth between a display controller and a memory device is detected to obtain bandwidth characteristics. An image format to be used is determined by comparing the bandwidth characteristics with a preset mapping relationship between at least two image formats and the bandwidth characteristics. A current image format is updated by the determined image format to be used if the determined image format to be used is different from the current image format. The image data in the memory is then read out according to the current image format.
