My customer would like to adjust CP_BRIGHTNESS register in ADV7482 in RGB output mode.
But unfortunately it does not work well.
If set 0x3C(CP_BRIGHTNESS) = 0x14, whole image was getting green when original image was gray scale.
brightness should affects only luminance, not color.
I also found similar Question on this EZ below.
but a conclusion of this post was not solved its problem.
CP_MODE_GAIN_ADJ will work like contrast, NOT brightness. (black level is not changed with CP_MODE_GAIN_ADJ)
My customer would like to know how to adjust brightness in RGB output mode.]
I checked all registers in CP block but there is no solution.
Would you please advise me?
Input format YPbPr 709
Output format RGB
csc_coeff_sel[3:0]=1111:CP CSC configured in automatic mode.
vid_adj_en=1:Enable color controls
cp_inp_color_space[3:0]=1111:In HDMI/MHL mode, input color space depends on color space reported by HDMI/MHL block.
cp_rgb_out=1:RGB color space output
csc_coeff_sel_rb[3:0]=0011:YPbPr 709 to RGB
