Abstract
An image brightness adjusting method is provided. The brightness values of all pixels of the image are firstly increased in various increasing degrees. Next, the increased brightness values are decreased in various decreasing degrees according to the original brightness values, thereby avoiding over-increasing the brightness values of the image. Moreover, the use of the color saturation values to adjust the brightness values can avoid the unnatural image appearance.
