White Balance; Lut; Binarization; 5-Point Interpolation - Sony XCL-S600 Technical Manual

White Balance

The white balance can be automatically adjusted once
when the WHITEBALANCE-AUTO 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 (AWB-FRAME). For manual correction, the
FINE command should be executed. The white balance
can be set finely per sensor tap. Therefore, a fine
adjustment should be made if the color difference
between sensor taps cannot be adjusted completely by
AWB.

For reference
If the color offset between the left and right sensor taps
cannot be cleared through fine adjustment using the
FINE command, adjustment of the black level may
work. Set the R, G, and B FINE levels to ×1 (256), align
the black levels, and then use the FINE command to
make fine adjustments. This tends to occur in low
temperature environments and when analog gain is set
high.

LUT

Five types of presets are provided. Specify using a 12 bit
value. Binarization, 5-point interpolation, and arbitrary
setting can be changed.

The binarization threshold can be changed.

5-point interpolation
The values of output points 1 through 5 that correspond
to input points 1 through 5 can be changed. Linear
interpolation is performed between interpolation points.
