HISTOGRAM EQUALIZATION |
摘要 |
In a method of histogram equalization of an image signal (Y), a histogram of the image signal (Y) is determined (HC), the image signal (Y) is processed (HP) in dependence upon the histogram to obtain a modified signal (Ymod), and the modified signal (Ymod) is enhanced (E) where said modified signal (Ymod) falls below said image signal (Y). Preferably, the enhancement (E) is color saturation (RGBsat) dependent. |
