Patent ID: 7292233

Claim:
A display controller that controls display of color data from a display data source on a display unit, comprising: a display data source interface that receives color source data described in a first color space from the display data source and outputs interface data described in the first color space using a clock frequency of f; a resizer that receives the interface data from the display data source interface described in the first color space and that trims and compresses the interface data and outputs resizer data described in the first color space using a clock frequency of f; a color space converter that receives the resizer data and converts the resizer data into converted data described in a second color space using a clock frequency of f/n, where n is an integer; and a display unit interface that receives the converted data from the color space converter and that outputs display data described in the second color space to the display unit using a clock frequency of Nf, where N is an integer.
