AMBIENT LIGHT-DEPENDENT VIDEO-SIGNAL PROCESSING

摘要

In an ambient light-dependent video-signal processing method comprising the steps of measuring (LDR) an amount of ambient light to obtain a measured amount of ambient light, and processing (VSP) a video signal in dependence upon the measured amount of ambient light, the video signal is substantially immediately affected when there is a large change in the measured amount of ambient light, while the video signal is affected upon an occurrence of a scene change when there is a small change in the measured amount of ambient light.
