摘要：Methods and apparatuses to varying the apparent brightness of a display aredescribed. The change in apparent brightness is accompanied by unchanged in relative
contrast, rendering a display with higher or lower brightness while maintaining contrastfidelity. In exemplary embodiments, the signals for the middle tone levels are adjusted toincrease or decrease the brightness intensity, while keeping constant the gammacorrection. This maintains the relative contrast of images while rendering them at adifferent brightness. Implementations of the present process include an adjusted gammacorrection lookup table, incorporated in the video card to modify the video signal beforereaching the display. The present invention can be used for matching the brightness oftwo or more displays or to provide compensation for variations in display characteristicsto ensure consistency in display brightness within a data processing model.
