Abstract:
1. An adjusting apparatus for adjusting the brightness of an image, the image comprising a plurality of pixels, the plurality of pixels comprising a center pixel and an initial pixel, said adjusting apparatus comprising: a detecting module for receiving the image and detecting the brightness of each pixel among the plurality of pixels; a calculating module coupled with the detecting module, based on a distance between the center pixel and the initial pixel, the calculating module respectively calculating a distance between each of the plurality of pixels and the center pixel; and a gain module coupled with the calculating module, based on distances between each of the plurality of pixels and the center pixel calculated by the calculating module, the gain module respectively adjusting the brightness of each of the plurality of pixels; wherein each of the plurality of pixels is respectively corresponding to a coordinate, the calculating module respectively performs a shifting calculation on each coordinate to generate a shifted coordinate, the calculating module also generates the distances between each of the plurality of pixels and the center pixel based on the shifted coordinate and the distance between the center pixel and the initial pixel; and wherein the coordinate of the center pixel is (x wherein ((a−i+1)<<1) represents performing the shifting calculation on (a−i+1) toward left.
