ABSTRACT:
A method for color conversion is disclosed. The method includes the steps of generating constants from a number of points, spacing and an endpoint for YUV point spacing, adding a constant to a value representing image data to clamp the value towards a predetermined maximum range of image points, subtracting a second constant from the resulting sum value to clamp the sum value towards a predetermined minimum range representing points in an image graph, shifting the resulting difference using spacing information to generate a value for Y,U,V values, and combining the resultant Y,U,V values to generate palette indexes to represent given image data.
