Pixel Sensitivity 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 vertical binning setting are changed significantly.
*) Correction data is saved for DSNU (PixelBlackCorrect) / PRNU (PixelGainCorrect)
according to the conditions adjusted at the factory.
*) 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)
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.
DSNU Correction (Pixel Black Correct)
DSNU (dark signal non-uniformity) is a variation between pixels in the dark areas
generated by the sensor. 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 DSNU may change.
Black level
[Correction procedure]
1. Specify the user area to save the gain correction value with
[PixelGainCorrectionMode] of [Correction].
2. Gain correction data is automatically generated by [CalibratePixelGainCorrection]
of [Correction] and saved in the user area specified in 1.
3. You can check the execution result of gain correction by
[PixelGainCalibrationResult] of [Correction].
