Usually the image sensors have some defective pixels from
the born and they can be compensated digitally by the image
signal processor.
This menu provides the defective pixel corrections in two
ways. LIVE DPC compensates the defective pixels at real time.
CAUTION: High setting of LEVEL in LIVE DPC can reduce
STATIC DPC detects the defective pixels at dark with lens clo-
sed and saves their data for compensation. When starting the
detection, camera closes the lens automatically and detects
the white dot noise exceeding the amplitude defined by LEVEL.
However lens cap is strongly recommended for closing lens
because some lenses are not closed perfectly by its iris.
Descriptions
LIVE DPC compensates the defective pixels at real time for whose pixel amplitude
exceeds the threshold.
AUTO: Enables LIVE DPC and dynamically compensates the defect pixels whose
amplitude exceeds the threshold calculated according to AGC. At low light,
more defect pixels are compensated because the threshold becomes lower
due to high AGC.
ON: Enables LIVE DPC and compensates the defect pixels whose magnitude
exceeds the threshold set by LEVEL.
CAUTION: High setting of LEVEL in LIVE DPC reduces the sharpness
OFF: Disables LIVE DPC
LEVEL is a threshold for white dot noise level caused by a defect pixel and is
effective when LIVE DPC is AUTO and ON.
Defect pixels exceeding LEVEL will be compensated and cleared.
Lower setting in LEVEL compensates more pixels.
STATIC DPC detects the defect pixels at dark with lens closed.
The detected pixels are saved for compensation.
ON enables the compensation for the detected defect pixels.
OFF does not apply the compensation.
Pressing will execute STATIC DPC.
Camera closes the lens automatically and detects the defect pixels.
CAUTION: Lens cap is highly recommended for closing because the iris of
some lens is not closed perfectly.
LEVEL is a threshold for white dot noise level caused by a defect pixel and is
effective for STATIC DPC only.
Defect pixels exceeding LEVEL will be compensated and cleared.
Lower setting in LEVEL compensates more pixels up to 04 pixels but too low
setting can't compensate the entire image because most of regular noise are
detected as a defect pixels at the top area of image and the number of defect
pixels are filled with them up to 04.
