【発明の名称】色信号クリッピングまたはリミッティング装置
Document Type and Number:
Japanese Patent JP3377243
Kind Code:
B2
Abstract:
A color video signal processing system determines when one component color signal has been limited by clipping and limits the other component color signals to maintain accurate hue in the reproduced image. In one system, the other color signals are held at their values at the instant the one signal was detected as being clipped until the signal is no longer clipped. In another system, an attenuation function is applied to the unclipped color signals when any one color signal is detected as being clipped.
