发明名称 Ambient light-dependent video-signal processing
摘要 In an ambient light-dependent video-signal processing method including 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 processed when there is a large change in the measured amount of ambient light, while the video signal is delayed being processed until an occurrence of a scene change in the video signal when there is a small change in the measured amount of ambient light.
