ABSTRACT:
The invention provides a display apparatus for producing a color image in which the color of each picture element is defined by the intensities of component red, blue and green primaries and is coded as a binary number having r bits defining 2.sup.r intensity levels for red, g bits defining 2.sup.g intensity levels for green, and b bits defining 2.sup.b intensity levels for blue, where g.ltoreq.7, (g-r)=1 or 2, and (g-b)=2. In a particularly advantageous embodiment of the invention the image has a resolution of substantially 4 pels per mm or greater, and g.ltoreq.4.
The invention also includes a method of coding a color image as defined above.
