<p>The invention provides a display apparatus for producing a colour imagein which the colour 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 2r intensity levels for red, g bits defining 2g intensity levels for green, and b bits defining 2b intensity levels for blue, where g < 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 < 4. The invention also includes a method of coding a colour image as defined above.</p> |
