Patent ID: 8218089

Claim:
A video signal processing apparatus comprising: a gain inverse correction means for receiving a video signal having been subjected to automatic gain control and gain information indicating a gain set by the automatic gain control, giving an inverse correction gain resulting in an inverse correction characteristic to the gain indicated by the gain information to the received video signal and outputting the video signal; a texture component removing means for removing a texture component from the video signal that is output from the gain inverse correction means; a gain inverse-inverse correction means for giving an inverse-inverse correction gain resulting in a correction characteristic that is inverse to the inverse correction gain to the video signal that is output from the texture component removing means; a texture component extracting means for extracting a texture component signal, utilizing the video signal that is output by the gain inverse correction means and the video signal that is output by the texture component removing means; and a signal synthesizing means for synthesizing a structure component signal based on the video signal that is output by the gain inverse-inverse correction means and the texture component signal to output a video signal.
