9.
SSO Percent
: Sets the value of Smart Scene
Optimization (SSO). Defines the histogram
percentage which will be mapped linearly.
10. Tail Rejection : Defines the percentage of pixels
that are a priori excluded from equalization.
11. IIR filter : Sets the IIR filter coefficient. The filter is
used to define the speed with which AGC reacts
to variations in the scene.
12.
Info Threshold
: Defines the difference between
close pixels used to determine whether or not
the image contains information.

This is a dynamic self-configuration menu based on
the choice made and shows the parameters on which
it is possible to operate.
9.1.12.6 ROI Setup Menu
Once inside the ROI Configuration Menu it is
possible to change the region of interest (ROI) used
by the AGC algorithm to calculate the contrast and
brightness levels of the image.
1.
P1 Left: Sets the left limit of the ROI.
2. P1 Top: Sets the upper limit of the ROI.
3.
P2 Right:
Sets the right limit of the ROI.
4. P2 Bottom: Sets the lower limit of the ROI.

9.1.12.6.1 Examples of ROI definitions
If you want a large full screen ROI, it is necessary to
input the following coordinates: P1A (LEFT: -512, TOP:
-512), P2A (RIGHT: +512, BOTTOM: +512). The ROI
highlighted in grey is defined as follows: P1B (LEFT:
-256, TOP: -256), P2B (RIGHT: 0, BOTTOM: 0).
