Instead of manually setting the analog gain to a specific value, the<br />
camera can determine appropriate gain values. This command<br />
calculates and sets the analog gain according to the algorithm<br />
determined by the first parameter.<br />
ccg i t i<br />
i<br />
t<br />
Calibration algorithm to use.<br />
1 = This algorithm adjusts analog gain so that 8% to 13% of<br />
tap region of interest (ROI) pixels are above the specified<br />
target value.<br />
2 = This algorithm adjusts analog gain so that the average<br />
pixel value in tap’s ROI is equal to the specified target<br />
value.<br />
3 = This algorithm adjusts digital gain so that the average<br />
pixel value in tap’s ROI is equal to the specified target.<br />
4 = This algorithm adjusts the analog gain so that the peak<br />
tap ROI pixels are adjusted to the specified target.<br />
Tap value. Use 0 for all taps or 1 to 2 for individual tap<br />
selection if you are using the two tap model.<br />
i<br />
Calculation target value in a range from 1024 to 4055DN<br />
(12 bit LSB).<br />
Notes: • This function requires constant light input while executing.<br />
• If very few tap pixels are within the ROI, gain calculation<br />
may not be optimal.<br />
• When all taps are selected, taps outside of the ROI are set to<br />
the average gain of the taps that are within the ROI.<br />
• Perform analog gain algorithms before performing FPN and<br />
PRNU calibration.<br />
• All digital settings affect the analog gain calibration. If you<br />
do not want the digital processing to have any effect on the<br />
camera gain calibration, then turn off all digital settings by<br />
sending the commands: 73Hsdo 0 0, 74Hepc 0 0, 75Hssb 0 0, and<br />
76Hssg 0 4096<br />
Example: ccg 2 0 3040<br />
