Image Acquisition Control
Basler scout light 67
Formula 2:
Calculates the maximum frame rate based on the exposure time for the acquired frames:
Where the constant C
3
depends on the camera model as shown in the table below:
Formula 3:
Calculates the maximum frame rate based on the number of packets needed to transmit a captured
frame from the camera to your host PC via the IEEE 1394 bus:
(round the result up to the nearest integer)
Example
Assume that you are using a monochrome slA1000-30fm camera set for an exposure time of 2000
µs and for 600 x 400 resolution. Also assume that you have checked the value of the Payload Size
parameter and the Packet Size parameters and found them to be 327100 and 8192 respectively.
Formula 1:
Max Frames/s = 51.7 frames/s
