Claim Text:
1. A method performed by an apparatus for color correction of a three dimensional display device, the method comprising: (a) generating a pixel of a grey color having three separate pixel color channels having substantially equal color intensity values for each of the pixel color channels; (b) displaying a plurality of the pixel on the display device; (c) receiving adjusted color intensity values for only two of the three separate pixel color channels, wherein the adjusted color intensity values are based on a user perceiving the pixel as being closest to a perceived grey color, without using a photometer, and wherein other one of the three separate pixel color channels is unadjusted; (d) calculating corrected color intensity values for the pixel color channels using the adjusted color intensity values and the pixel color intensity values; (e) generating look-up tables to convert the pixel color intensity values to the corrected color intensity values; and (f) performing (a) through (e) repetitively three or more times (N≧3) for three or more different colors of grey.
