Method of exposure compensation for simulating the dynamic range of human eyes |
摘要 |
A method of exposure compensation for simulating the dynamic of human eye comprises the following steps: sampling the brightness of an image; plotting a brightness level graph; converting the brightness level graph into a histogram of brightness; converting the histogram of brightness into a percentile diagram of brightness; converting the percentile diagram of brightness into a diagram of gamut curve; and replacing the gamut curve of the original image with the new gamut curve to obtain a modified image. Thereby, color level of the large part of low brightness can be raised to show the details of the image, and an excellent image quality is available.
