Abstract
A method, apparatus and system for visual gamma correction of a display system includes retrieving input gamma information from input content, determining at least one pattern representing luminance of the received content based upon at least the retrieved gamma information, displaying the at least one determined pattern representing the luminance of the received image content and at least one corresponding reference image on the display system, and adjusting the brightness and contrast of the least one reference image on the display system to approach the luminance of a corresponding determined pattern to determine a corrected gamma for the display system.
