Pixel Sensitivity Correction
Related Topic:
JAI Custom Control Pixel Correction
Correct variations between the sensor’s pixels.
Calibration must be performed within the camera and correction data must be created
beforehand. DSNU (PixelBlackCorrect) / PRNU (PixelGainCorrect) can be reduced using that
correction data.
We recommend performing calibration and creating correction data whenever the line rate setting
or Analog base gain setting or vertical binning setting are changed significantly.
Refer to the following topics on how to perform the calibration.
Notes:
l
Correction data is saved for DSNU (PixelBlackCorrect) / PRNU (PixelGainCorrect)
according to the conditions adjusted at the factory.
l
We recommend performing DSNU and PRNU calibration again whenever the line rate
setting is changed significantly.
l
A single correction data entry can be saved on the camera for each user. When
calibration is performed, the correction data is saved to the non-volatile ROM at the
same time.
PRNU Correction (Pixel Gain Correct)
Related Setting Items:
JAI Custom Control Pixel Correction
PRNU (photo response non-uniformity) is a variation between pixels generated by the sensor
under bright conditions. If the line rate is slowed or a long exposure time is set, the dark current in
the sensor may change and the state of the PRNU may change.
1. Specify the user area (User1 ~ User3) to save the gain correction value with
PixelGainCorrectionMode
(
JAI Custom Control Pixel Correction
).
Note:
You cannot perform calibration when
Off
or
Default
is selected.
