6.4.1 Increasing the Maximum Allowed Line Rate
You may find that you would like to acquire lines at a rate higher than the maximum allowed with
the camera’s current settings. In this case, you must first determine what factor is most restricting
the maximum line rate. The descriptions of the three factors that appear below will let you determine
which factor is restricting the rate.
Factor 1:
Factor 1 is the sensor readout time. The readout time for a particular sensor is a fixed value and
thus the maximum line acquisition rate as determined by the readout time is also fixed. The table
below shows the maximum line rate (in lines per second) based on sensor readout time for each
camera model.
Factor 2:
Factor 2 is the exposure time. You can use the formula below to calculate the maximum line rate
based on the exposure time for each acquired line:
Where the constant C
1
depends on the camera model as shown in the table below:
For more information about setting the exposure time, see Section 6.1.5.3 on page 56.
Formula 3 calculates the maximum line rate based on the amount of time it takes to transmit the
pixel data for an acquired line from the camera to the host PC:
