Figure 2.30 - Long Integration
During the integration time the camera has to be kept still otherwise a
motion smear will appear on the image.
The minimum value for long integration is camera dependent:
- IPX-VGA210/210 – 10 ms.
- IPX-1M48 – 30 ms.
- IPX-2M30/H – 70 ms.
- IPX-4M15 – 120 ms.
- IPX-11M5 – 420 ms.
Long Integration cannot be enabled in Trigger mode.
Long Integration cannot be enabled in Programmable Frame Rate
mode.
Long Integration cannot be enabled in Shutter mode.
Long time integration significantly decreases the signal
More electrons will be collected from the pixels dark current and thus
the camera noise will increase significantly.
