Contrast adjustment applies to YUV data. The Y channel is multiplied by 

the value contained in the register field. This signed fixed-point number is in 3i.6f 

format with the first 3 MSBs as the integer value and the last 6 LSBs as the fraction 

value. The allowed contrast value ranges from 0 to 7.53125 decimal. 

Bypassing Contrast, for YUV modes and for source data in RGB format, is accomplished 

by programming this field to a field value that represents 1.0 decimal or 001.000000 

binary .

This field provides the brightness adjustment with a 8-bit 2 s 

compliment value ranging [-128, +127]. This value is added to the Y value after 

contrast multiply and before YUV to RGB conversion. A value of zero disables this 

adjustment affect. This 8-bit signed value provides half of the achievable brightness 

adjustment dynamic range. A full range brightness value would have a programmable 

range of [-255, +255]. 

Bypassing Brightness for YUV formats and for source data in RGB format, is 

accomplished by programming this field to 0.
