(a) An 8-bit representation of the LUT for the formation of the oblique viewing grayscale. The figure illustrates the measured luminance response of the LCD display (IBM T221) at the normal, 30-degree, and 50-degree oblique viewing orientations (19). The oblique responses are the averages of the display performance in the 45-degree and 135-degree azimuthal directions. The arrows note two examples. The LUT was formed as a transformation of the images in the 12-bit pixel value space such that the image pixel in the normal viewing orientation would render a grayscale value consistent with the desired 30-degree and 50-degree orientations. (b) Histogram of a typical image displayed with grayscale corresponding with 0-, 30-, and 50-degree viewing angles.
