Defect pixel correction (only Guppy F-503)
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’s EEPROM.
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.
