Abstract
The invention discloses an image processing apparatus and an image processing method, for adjusting the contrast of an input image. The input image consists of plural pixels and each pixel has a respective input lightness. The apparatus can perform a normalization procedure on the pixels to obtain a respective normalized lightness of each pixel. In addition, the apparatus generates lightness statistics based on the pixels and determines plural threshold lightness based on the lightness statistics. According to the normalized lightness and the threshold lightness, the apparatus can change the lightness gain of a specific region of the input image dynamically, and thereby adjust the contrast of the input image.
