Title: Automatic brightness adjuster and method therefor
Inventor: MUNENO KOICHI
IPC: H04N1/407
Filed: 2002-11-06
Abstract: <P>PROBLEM TO BE SOLVED: To provide an automatic brightness adjuster and a method for automatically adjusting the brightness of each of a plurality of brightness regions according to a mean brightness level of a display screen.  <P>SOLUTION: The adjuster detects a main brightness of a display screen, and automatically adjusts contrast and the brightness of each of a plurality of predetermined brightness level regions, based on the detected means brightness. For a low-brightness image, it raises an amplification degree related to the contrast and the brightness to make bright the image easy to see. For a high brightness image, it lowers the amplification degree to suppress glaringness. This provides an image with an appropriate brightness for a user, irrespective of the brightness of the image. Especially, the brightness is divided into a plurality of levels and the contrast and the brightness are controlled every region to avoid rapidly changing the image. A buffer region is added between the regions to diverge gain adjustment, this improving the problem of flickering on the screen.  <P>COPYRIGHT: (C)2004,JPO
