The adaptive tone correction of moving image for LCD power-saving

Abstract

In viewing and listening of the video in mobile environment, it is a subject to extend time of operation under limited power resource. When the back light of a liquid crystal display was made dark and consumption of electric power was reduced, it was a fault to become very hard to see by the fall of luminosity and contrast. Even in such a case, in order to maintain the brightness of appearance, the method of adaptive tone correction according to the statistical character of video is examined, and from the result of having experimented, while verifying about a visual effect, the application possibility to power-saving of a liquid crystal display is examined.
