Patent ID: 8390532

Claim:
A video display apparatus comprising a display screen of which is configured by combining a plurality of video display units in each of which light emitting display elements are arranged in a matrix manner, wherein there is provided a luminance correction means that corrects the luminance of video data situated in a correction subject area including respective end regions, of a first video display unit and a second video display unit, that face each other, in accordance with a spacing between the first video display unit and the second video display unit, wherein, by setting respective addresses for each of the plurality of video display units and specifying a range of the set addresses, luminance correction over the plurality of video display units is performed, and wherein, when the spacing between the adjacent first and second video display units is smaller than a standard unit spacing, a bright linear noise is caused at a place between the first video display unit and the second video display unit, the luminance correction means reduces the luminance of video data situated in the correction subject area; and when the spacing between the first video display unit and the second video display unit is larger tan a standard unit spacing, a dark linear noise is caused at a place between the first video display unit and the second video display unit, the luminance correction means raises the luminance of video data situated in the correction subject area.
