摘要： A correction signal capturing section of a skin color correction processing section of an image processor captures WB-corrected R1G1B1 signal values, a WB inverse correction section performs inverse correction, a YCbCr conversion section converts obtained R2G2B2 signal values into Y1Cb1Cr1 signal values. A skin color pixel region detection section detects pixels corresponding to skin color pixel regions, a skin color correction section performs skin color correction to the Y1Cb1Cr1 signal values and obtains Y2Cb2Cr2 signal values, and a RGB conversion section converts the obtained Y2Cb2Cr2 signal values into R3G3B3 signal values. A WB correction section performs WB correction to the R3G3B3 signal values and obtains R4G4B4 signal values. An output section outputs the image signals of the image reconstructed by applying said R4G4B4 signal values to the skin color pixel regions and by applying said R1G1B1 signal values to the pixel regions other than the skin color pixel regions.

摘要： A video displaying apparatus is provided that can change light-modulation rate of a backlight source in accordance with changes in a feature quantity of an input video signal based on a difference between times required for the light adaptation and the dark adaptation.A video displaying apparatus includes a liquid crystal panel 3 that displays an input video signal, a backlight source 9 that applies light to the liquid crystal panel 3, an APL detecting part 6 that detects APL of the input video signal, and a control microcomputer 8 that variably controls a change amount of emission luminance of the backlight source 9 for each predetermined time based on the detected APL. The control microcomputer 8 performs control such that the change amount for the APL of the input video signal changing to a higher quantity becomes greater than the change amount for the APL of the input video signal changing to a lower quantity.

摘要： A liquid crystal display apparatus and a television receiver enable an improvement in visibility in a low-tone range in a configuration in which the brightness of a backlight is changed on the basis of brightness information relating to an image. The apparatus includes an APL curve setting portion and a histogram luminance modulating portion which adjust the brightness of the backlight and a tone signal on the basis of the average brightness of the image and the brightness histogram of the image. A black extending portion applies gamma correction to the tone signal adjusted by the histogram luminance modulating portion on the basis of a previously set gamma value.
