<P>PROBLEM TO BE SOLVED: To enable an image to be displayed as more natural image. <P>SOLUTION: In a television receiver for receiving a video signal subjected to inverse gamma correction and displaying an image corresponding to the video signal onto a display section 12, a signal correction section 111 corrects a luminance signal Y included in the video signal so that the luminance of the image corresponding to the video signal becomes a luminance corresponding to the visibility of a person viewing the image displayed on the display section 12. A contour correction section 31 corrects the contour of the luminance signal Y on the basis of the corrected luminance signal Y. A YCbCrRGB conversion section 34 generates an RGB signal for displaying the image on the display section 12 on the basis of the luminance signal Y whose contour is corrected and color difference signals Cb, Cr included in the video signal. A panel gamma correction section 35 applies gamma correction to the generated RGB signal in response to the gamma characteristic of the display section 12. The technology above can be applied to television receivers. <P>COPYRIGHT: (C)2007,JPO&INPIT |
