VCBM_BRIGHTNESS
R/W
0
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 ag is raised.
15
VCBM_U2C
R/W
0
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
14
VCBM_M2C
R/W
0
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
13
VCBM_L2C
R/W
0
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.
12
VCBM_U2CO
R/W
0
Back-end reverse offset (for two’s complement mentioned above)
control bit for upper channel.
(Yout/Rout = Yout/Rout - VCBM_BLK_OFFSET described below)
11
VCBM_M2CO
R/W
0
Back-end reverse offset (for two’s complement mentioned above)
control bit for middle channel
10
VCBM_L2CO
R/W
0
Back-end reverse offset (for two’s complement mentioned above)
control bit for lower channel
9:0
VCBM_BLK_OFFSET
R/W
0x100
Signed 10-bit two's complement to binary offset (or Black-level
offset). +256 is the default value.
