Dark Signal Non-uniformity Correction

In theory, when a digital camera acquires images in complete darkness, all of the pixel values in the image

should be near zero and they should be equal. In practice, however, slight variations in the performance of the

pixels in the sensor will cause some variations in the pixel values output from the camera when the camera is

acquiring in darkness. This variation is known as Dark Signal Non-Uniformity (DSNU). The VT Camera Link

cameras provide the DSNU Correction feature.

The commands related to DSNU are as follows.

Configurator Parameters Command

Value

Description

Generate All

gdda

Generates and saves the DSNU data for each Analog

Gain setting values (

4).

Generate

gdd

Generates the DSNU data.

Save to Flash

sdd

Saves the generated DSNU data in the non-volatile

memory.



The generated data by executing the

Generate

parameter are saved in the volatile memory so that

the data lost if the camera is reset or if power is

turned off. To use the data after the camera is

powered on or reset, save them in the non-volatile

memory.

Load from Flash

ldd

Loads the DSNU data from the non-volatile memory into

the volatile memory.
