MARLIN F-131: AOI frame rates
This model uses a CMOS sensor with global shutter. As mentioned earlier for
the non pipelined global shutter, the integration time must be added to the
readout time to define the maximum frame rate. The next table gives an
example: (it assumes full horizontal width and an integration time of 1 ms).
Read note in Chapter Video formats, modes and bandwidth on page 137.
Limiting the field of view in both vertical as well as horizontal direction gives
a proportional increase in speed. This is in contrary to CCD sensors where the
horizontal image limit does not increase the frame rate.
In order to calculate the maximum achievable frame rate (with certain expo-
sure time) the following equation can be used:
AOI height / pixel Frame rate / fps
1.024 24.42
960 26.01
600 40.97
480 50.69
240 96.46
120 175.84
60 298.78
