Description
Brightness Setting (Signed value ranging from -512 to 511 which is
equivalent to -100% to +100% brightness change for nominal
signals having a range from -256 to 255 with a contrast setting of
256)
Nominal value: 0
Brightness control is performed after e color space conversion in
associated with the contrast control.
Y‘‘ = Y‘ + VCBM_BRIGHTNESS if VCBM_U2B flag is raised.
Two’s complement to binary offset conversion for contrast control
(upper channel Y’/R’ = Y/R + VCBM_BLK_OFFSET)
Needs to be set in case the data format entering the VCBM is YUV
or RGB
Two’s complement to binary offset conversion for contrast control
(middle channel U/G)
Needs to be set in case the data format entering the VCBM is RGB
Two’s complement to binary offset conversion for contrast control
(lower channel V/B)
Needs to be set in case the data format entering the VCBM is RGB.
Back-end reverse offset (for two’s complement mentioned above)
control bit for upper channel.
(Yout/Rout = Yout/Rout - VCBM_BLK_OFFSET described below)
Back-end reverse offset (for two’s complement mentioned above)
control bit for middle channel
Back-end reverse offset (for two’s complement mentioned above)
control bit for lower channel
Signed 10-bit two's complement to binary offset (or Black-level
offset). +256 is the default value.
Color space conversion matrix coefficient - C11 matrix component
Color space conversion matrix coefficient - C12 matrix component
Color space conversion matrix coefficient - C13 matrix component
Color space conversion matrix coefficient - C21 matrix component
Color space conversion matrix coefficient - C22 matrix component
