White Balance; Lut; Binarization; 5-Point Interpolation - Sony XCG-CG160 Technical Manual

White Balance

The white balance can be automatically adjusted when
the BalanceWhiteAuto command is executed. The
detection area is set to the screen center by default. The
detection area can also be displayed on the screen.
The detection frame can be changed arbitrarily
(DetectAreaWBAuto). For manual correction, the
GainDigital should be changed.
