Configuration of the camera

Defect pixel correction

Definition The defect pixel correction mode allows to correct an image with defect pixels.

Via threshold you can define the defect pixels in an image. Defect pixel correc-

tion is done in the FPGA and defect pixel data can be stored inside the camera.

DPC = defect pixel correction

WR = write

RD = read

MEM, Mem = memory

Note



• Defect pixel correction is always done in Format_7

Mode_0.

• When using defect pixel correction with binning and

sub-sampling: first switch to binning/sub-sampling

modus and then apply defect pixel correction.
