Exposure Start and Exposure Time Control
Basler sprint Mono Cameras 75
Formula 1 calculates the maximum line rate based on the exposure time:
Formula 2 calculates the maximum line rate based on the sensor readout time:
Where: n = 2 if the camera is set for the Dual Line [ Max 140 kHz ] line acquisition mode (see
Chapter 3 on page 39 )
n = 1 for all other line acquisition modes
Max Seg AOI Pixels is the number of AOI pixels in the segment that contains the most
AOI pixels (see the explanation of Max Seg AOI Pixels on page 77 for more details)
Formula 3 calculates the maximum line rate based on the amount of time it takes the camera to
process the pixels read out from the sensor:
Where: PPR is the pixel processing rate for your camera model as stated in the table below:
Note
In 8 tap video data output mode at 80 MHz, the maximum line rate for the
spL2048 camera will be less than 140 MHz. The camera will, however, reach
a maximum line rate of 140 MHz in 4 tap video data output mode at 80 MHz
and 8 tap video data output mode at 40 MHz.
