Programmable color mapping |
| abstract |
A circuit and method of operation for selectively mapping a first digital signal representative of an image to be produced into a second digital signal representative of the color quality of said image in terms of hue, saturation, and lightness. The eight possible 3-bit pixel signals which can occur in a raster line of image data read from memory 20 via register 23 are each mapped into a 6-bit signal selected from the 64 possible via conversion code stored in a PAM in colour map unit 24. The 6-bit signal controls the displayed picture element according e.g. to a bit pair for each colour gun in CRT 30, as in Fig. 3A. A method is also disclosed for using such a mapping circuit to select a particular image to be formed from a group containing a mutually independent plurality of such images. <IMAGE> |
