Abstract

This paper proposes a new method for improving improper exposure images. Disappearance of color information and deterioration of brightness and contrast are occurred in images when images are taken under a bad condition such as backlights. Generally, improper exposure images have the feature that the color difference is small, and color frequency of them is larger than that of the proper exposure image. In this method, this feature is extracted by using a new color histogram space based on human perception, and improve over or under exposure images visibility.
