An integrated circuit has a substantially non-customizable hardware portion and a mask-programmable logic portion. An image processing function common to many different makes and models of a type of electronic consumer device (for example, an image display device) is performed by the substantially non-customizable hardware portion. The substantially non-customizable hardware portion also outputs pixel data in both a first color space format and a second color space format. The mask-programmble logic portion can be mask-programmed for an individual manufacturer of electronic consumer devices such that the mask-programmable logic portion performs an additional special function specific to the electronic consumer devices of the individual manufacturer. Certain functions are better or more easily performed on pixel data in one color space format than another. Pixel data is therefore supplied to the mask-programmable hardware portion in multiple different color space formats, or in a selectable one of multiple different color space formats.
