摘要：
In an image compensation method, formats of images are identified based on ambient color quantity information. If the image is in text format or of high contrast, over compensation is barred to avoid edge effect. A compensation coefficient is set basing on edge eigenvalue of images. The compensation value is fine tuned based on a threshold value to obtain finer compensation result.
