A display controller (100) is configured for creating a translucency effe ct 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 conv erter (106) adapted for color model transformation of the image data from th e first color model to a second color model based upon a first predefined se t of transformation coefficients (108), as well as a second color model conv erter (116) adapted for color model transformation of the image data from th e first color model to the second color model based upon a second predefined set of transformation coefficients (118). The display controller is control lable to produce a destination image by selecting transformed image data fro m the second color model converter for the target image area (192, 194) and by selecting transformed image data from the first color model converter for other image area(s) (196) of the source image than the target image area.
