Claim One:
1. A display controller 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 comprising: a first color model converter adapted for color model transformation of said image data from said first color model to a second color model based upon a first predefined set of transformation coefficients, and a second color model converter adapted for color model transformation of said image data from said first color model to said second color model based upon a second predefined set of transformation coefficients, wherein the display controller is controllable to produce a destination image by selecting transformed image data from said second color model converter for said target image area and by selecting transformed image data from said first color model converter for another image area of said source image than said target image area, and wherein said first and second predefined sets of transformation coefficients are designed such that a visually noticeable difference between the target image area and said another image area will be perceivable for a human user when the destination image is presented on a display which is compliant with the second color model.
