Description
Calculates the cam era gain accord ing to
the selected algorithm .
i = Calibration algorithm to use.
1 = This algorithm ad justs analog
gain so that 8% to 13% of tap ROI
pixels are above the specified target
value.
2 = This algorithm ad justs analog
gain so that the average pixel value
in tap's ROI is equal to the
specified target value.
3 = This algorith m ad justs d igital
gain so that the average pixel value
in tap's ROI is equal to the
specified target.
4 = This algorithm ad justs the
analog gain so that the peak tap
ROI pixels are ad justed to the
specified target.
t = Tap value. Use 0 for all taps or 1
to num ber of CCD taps for ind ivid ual
tap selection.
i = Calibration target value in a range
from :
Algorithm 1 and 2: 1024 to 4055DN
(12 bit LSB).
Algorithm 3: 4095 to 65535. The
d igital vid eo values are m ultiplied by
this value w here:

betw een the m ost and least sensitive
pixel creating a uniform response to
light.
