Shutter Speed
You can set the exposure time (electronic shutter speed) of the camera in 1-line time units.
The exposure time can be calculated by the following formula.
Exposure time = 1 line time * (number of lines in 1 frame
–
shutter speed related register setting
value) + 13.73 [
μ
sec]
The 1-line time does not change even if the mode changes.
1 line time = 13.28us
When all pixels are output (2448 x 2048)
1 line time = 13.28 [
μ
sec]
Exposure time (min) = 0.1 [m sec]
Exposure time (max) = 700 [m sec]
When ROI is set
1 line time = 13.414 [
μ
sec]
When thinning (subsampling) is set
1 line time = 13.28 [
μ
sec]
Exposure time (min) = 0.1 [m sec]
Exposure time (max) = 700 [m sec]
* If you set ROI or thinning out, the brightness of the image will change because the exposure time
will change.
If you are using the SDK, you can use the Set / GetRealExposure function to
The exposure time can be set / acquired in 1
μ
s units.
* If the frame rate does not improve even though ROI or thinning transfer is performed,
The shutter speed setting value may be larger than the number of effective vertical pixels.
In that case, set the shutter speed setting value <effective vertical pixel count.
