Abstract
The invention provides a luminance adjustment system, comprising: a block division module (), a luminance representative value calculation module (), an edge information extraction module (), an adjustment gain calculation module (), a gain smooth processing module (), and a data modulation module (). By dividing an image into blocks, and combined with the luminance representative value and the amount of edge information amount indicating the complexity of the image of each block, the invention performs an individual luminance adjustment on each block, so that a more accurate adjustment can be achieved. As such, the invention can maintain details in darker part of the image, and to adjust the luminance of bright and complex part of the image to a greater extent.
