Abstract:
A display controller is configured for creating a translucency effect for a target image area of a source image containing image data expressed in a first color model. The display controller has a first color model converter adapted for color model transformation of the image data from the first color model to a second color model based upon a first predefined set of transformation coefficients, as well as a second color model converter adapted for color model transformation of the image data from the first color model to the second color model based upon a second predefined set of transformation coefficients. The display controller is controllable to produce a destination image by selecting transformed image data from the second color model converter for the target image area and by selecting transformed image data from the first color model converter for other image area(s) of the source image than the target image area.
