126 Basler sprint Mono Cameras
6. Begin acquiring lines either by generating an ExSync signal to trigger line capture or by setting
the camera for a free run exposure time control mode.
7. Signal the camera to generate a set of PRNU values:
a. You can start the generation of a set of PRNU values with the Camera Configuration Tool
Plus (see Section 7.1 on page 156). With the CCT+, set the value of the Generate
parameter in the DSNU & PRNU Shading Correction parameters group to Generate PRNU
Values or to Generate PRNU Values with DSNU.
b. You can also start the generation of a set of PRNU values by using a binary write command
(see Section 7.3 on page 196) to write a value to the Generate field of the Shading Value
Generate CSR (see page 178).
8. The camera must make at least 128 acquisitions to generate a set of PRNU values. If your
camera is set to control exposure with an ExSync signal, you must generate at least 128
ExSync signal cycles after you signal the camera to begin generating the values. If you are
running the camera in a free run exposure time control mode, you must wait long enough for
the camera to complete at least 128 acquisitions.
a. When the camera is capturing the lines it needs to create the PRNU shading values, the
line valid and data valid signals will go high and low as you would normally expect.
Note
When you generate the PRNU values in the step below, you will have two
options:
1. You can generate the PRNU values without using DSNU shading
correction. If you do this the pixel values used to calculate the PRNU
correction values will not be corrected for DSNU.
2. You can generate the PRNU values with using DSNU shading correction.
If you do this the pixel values used to calculate the PRNU correction values
will be corrected for DSNU. (For this option to work correctly, you must
have already generated DSNU values before you generate the PRNU
values.)
