What is dark field correction and how to use it?

Dark field correction is used to eliminate noise or defective pixels caused by high temperature, readout channels, or long exposure. Dark frames are frames captured without illumination, including noise or defective pixels. Subtracting dark frames from captured frames will preserve useful information and eliminate noise or defective pixels.

Please note that when conditions change, including temperature, exposure time, and gain settings, DFC must be performed again.

• Please cover the camera with a cap to reduce illumination.
• Set the number of dark frames. These dark frames will be averaged and used as reference for DFC.
• Click the "Capture" button to obtain dark frames.

• Check the "Enable" button to enable the DFC function.
