Off
– Defective Pixel Correction is turned off
Static
– Defective Pixels are corrected using the Defective
Pixel Map.
Dynamic
– Defective Pixels are identified dynamically on a
frame by frame basis. Once identified, defective pixels are
corrected on subsequent frames.
Combined
– Defective Pixels from the DPM are corrected
and any additional defective pixels identified dynamically are
also corrected. Dynamic Pixel Correction data is not retained,
if the camera is power cycled.
HPC
– enables Hot Pixel Correction (HPC) and allows either
static, dynamic or both static and dynamic defective pixel
correction. Each camera comes with a built-in Hot Pixel Map
(DPM) to correct for defective pixels. The user can upload a
custom HPM, if desired.
Off
– Hot Pixel Correction is turned off
Static
– Defective Pixels are corrected using the Hot Pixel
Map.
Dynamic
– Hot Pixels are identified dynamically based on a
user defined threshold on a frame by frame basis. Once
identified, hot pixels are corrected on subsequent frames.
Combined
– Hot pixels from the HPM are corrected and any
additional defective pixels identified dynamically are also
corrected. Dynamic Hot Pixel Correction data is not retained,
if the camera is power cycled.
Flat Field Correction:
enables or disables flat field correction to improve
uniformity.
Recommendation:
leave flat field correction checked.
FPN Correction:
the camera automatically corrects for column fixed pattern (FPN)
noise.
Recommendation:
leave FPN box checked.
Test Mode
:
Test Patterns
– the camera can output eight test patterns:
1.
Off – test mode is off.
2.
H Ramp – displays a stationary horizontal ramp image.
3.
V Ramp – displays a stationary vertical ramp image.
4.
H Ramp move – displays a moving horizontal ramp image.
5.
V Ramp move – displays a moving vertical ramp image.
6.
Crosshair – superimposes a cross, located in the center of the
CMOS images.
