Chip level system), R (Red, red)/G (Green, green)/B (Blue, blue), statistics with histogram R, G, B, R show value LR, BR
(backlight value)=LRmax(show value), PixelRij=LRij*255/BR(backlight value), Gamma/ white balance, backlight drive R lamp, G
Show value LG, BG(backlight value)=LGmax(show value), PixelGij=LGij*255/BG(backlight value), Gamma/ white balance, back
Optical drive G lamp, B show value LB, BB(backlight value)=LBmax(show value), PixelBij=LBij*255/BB(backlight value),
Gamma/ white balance, backlight drive B lamp, Display Unit VB1output (display unit VB1 output), the VB1, (face PANEL
Plate), Delay (delay).TV SOC first (System on Chip, systems-on-a-chip) is R the Content Transformation of image
(Red, red)/G (Green, green)/B (Blue, blue), and the histogram of R/G/B is counted respectively, it is with G therein
