Shutter (Exposure)
Configuring the setting
The setting is configured in µs unit. With the default
shutter value, the frame rate is 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 up to 60 sec
during operation. The exposure time that guarantees
image quality is up to two seconds.
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 along with auto
gain.
Combination of
Continuous AGC and
Continuous AE
AGC and AE coordinate with each other 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 work.
