Area gain
A separate digital gain can be set for a rectangular area
of preference 16 positions.
If multiple rectangular areas are duplicated, the gain
value of the low-numbered area takes priority.
Set area for Width/Height/OffsetX/OffsetY is same as “partial
read-out”.
Gain means 256=1 time. i.e. 8191=approx. 32 times. When
this is set to 0, selected area will be completely black.
* Area size and position settings are performed based on
the absolute coordinate value against the valid pixel.
Therefore, the area size and position range should be
set within the partial read-out range.
*1
This is used to set the area and gain.
*2
The area can be switched between valid/invalid
without changing the area.
*3
Reads out the current settings.
*4

Shutter (Exposure)
Configuring the setting
The setting is configured in µs unit. If you do not
prioritize the image quality, you can set it up to 60 sec
during operation. If the exposure time is long, it will be
easier to see the pixel defects.
Auto exposure (AE)
The shutter is set automatically by detecting the output
level. The target level is the same as the value of AGC-
LEVEL. This can be performed along with auto gain.
Combination of
Continuous AGC and
Continuous AE
AGC and AE coordinate with each other to adjust the
level automatically with AGC-LEVEL as the target
level. When the environment starts getting dark and the
shutter is released, AGC starts to work.
