* Specify the area size and position of the area gain in absolute
coordinate values relative to the effective pixels. Therefore, the range
of the area size and position needs to be set within the readout range.
Shutter (Exposure)
Configuration method
The setting is configured in µs units. The default shutter
value is the value with the frame rate maximized. During
free run operation, the frame rate is reduced by setting a
value bigger than the default shutter value. If you do not
prioritize the image quality, you can set it to a value of
up to 60 seconds during operation. If the exposure time
is long, it will be easier to see the pixel defects.
Note
The exposure times that can be set varies depending on
the mode.
Check the actual value by reading out after completing
settings.
* The minimum value varies depending on the settings.
Auto exposure (AE)
The shutter is set automatically by detecting the output
level. The target level is the same as the value of
GainAutoLevel. This can be performed in conjunction
with auto gain.
Combination of
Continuous AGC and
Continuous AE
AGC and AE operate together to adjust the level
automatically with GainAutoLevel as the target level.
When the environment starts getting dark and AE
reaches the upper limit, AGC starts to operate.
