ROI Gain () :
Set the Gain for the ROI Gain feature.
Read function : Not readable (one shot function)
Write function : “w roig” <value> ; Value from 0 to 2047 (U1.9) corresponding to a Gain range
from x1 to x1,999 and calculated as following : (1+ Gain/1024).
ROI Set () :
Set the ROI and apply the Gain for ROI Gain Feature.
Read function : Not readable (one shot function)
Write function : “w
rois
<val>” with <val> : Hexadecimal combination of Start and Stop
address for the ROI (both on 16bits) :
0xStartAdr0xStopAdr
Start address : from 0 to 8190 (0x000 to 0x1FFE)
Stop address : from 1 to 8191 (0x001 to 0x1FFF)
ROI Gain : How does it works
The ROI Gain feature comes in addition with the FFC (it’s applied and calculated after).
The maximum complementary Gain ix x2.
It can be applied in 2 commands :
First, set the ROI Gain value
Second, set the ROI (Region of Interest).
This second command applies the Gain on the ROI in memory and this is immediately
activated.
The ROI Gain is a “live” feature that can be overlapped but can’t be saved in memory.
Here is an example to apply a complementary gain of x1,5 (
512
) between the pixels #3051
(0x
0BEB
) and #4102 (0x
1006
), pixels included. The two commands are :
-
“w roig 512”
-
“w rois 0x0BEB1006”
Result with FFC activated :
Result with FFC not activated :
