Claim Text:
1. A method for adjusting contrast of an anaglyph image, the method comprising: receiving, at a first anaglyph transformer processor, a first input image signal and a second input image signal; generating, at the first anaglyph transformer processor, a first anaglyph signal from the first input image signal and the second input image signal; receiving and applying, at one or more contrast adjuster circuits, a contrast adjustment to the first input image signal, the second input image signal, and the first anaglyph signal; calculating, within a first summing device, a first difference between the contrast-adjusted first input image signal and the contrast-adjusted first anaglyph signal; calculating within the first summing device a second difference between the contrast-adjusted second input image signal and the contrast-adjusted first anaglyph signal; and receiving within a second summing device connected to a fine adjuster circuit signals for the first and second differences and calculating within a processor a fine adjustment value from summed first and second differences and applying a fine adjustment within the fine adjuster circuit as a gain adjustment, an offset adjustment, and a horizontal and vertical shift.
