3.12 Optimizing Offset Performance

Optimizing offset performance in the analog domain allows you to achieve a better
signal-to-noise ratio (dynamic range) than you would achieve by trying to optimize the
offset in the digital domain.

gla [x1] [x2]
[x1]
Optional parameter. This sets the start pixel to display
on screen. Allowable range is 1 to sensor pixel count.
This value does not affect the Min, Max, and Mean
statistics generated at the end of the line output.
[x2]
Optional parameter. This sets the end pixel to display on
screen. Allowable range is 1 to sensor pixel count. This
value does not affect the Min, Max, and Mean statistics
generated at the end of the line output.
•
If you do not specify a pixel range to display, the line output
will display all sensor pixels on screen.
•
If a region of interest has been set using the roi command,
the Min, Max, and Mean statistics at the end of the line
output include statistics for the region of interest only.
•
If you are using the 4 tap model, and your region of interest
is in one half of the sensor only (taps 1 and 2, or taps 3 and 4),
the values displayed on screen for the taps outside the ROI
are a mean of the ROI line statistics.
•
Values returned are in DN.
