Defect pixel correction
Definition The defect pixel correction mode allows to correct an image with defect pix-
els. Via threshold you can define the defect pixels in an image. Defect pixel
correction 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.
