Available Parameters: Extended Reading
Some parameters warrant an extended explanation. Section 6.3 provides further explanation:
6.3.1
Analog Control
The Analog Control parameters can be used to control and adjust the gain and the black level available
features. The correction is performed according to the following equation:
𝑃
𝑟𝑒𝑑
= (P
red
+ "BlackLevelRed") ∗ "GainRed"
𝑃
𝑔𝑟𝑒𝑒𝑛
= (P
green
+ "BlackLevelGreen") ∗ "GainGreen"
𝑃
𝑏𝑙𝑢𝑒
= (P
blue
+ "BlackLevelBlue") ∗ "GainBlue"
Where P is the pixel that is being corrected, the Black Level is the offset of said pixel and the Gain is the
gain of the pixel. Analog Black Level Controls the analog black level as an absolute physical value.
Represents the applied DC offset
6.3.2
Balance White Auto
Automatic white balance adjustment, compensate sensor output colors to true colors. The algorithm
works on the assumption that average color of image in selected ROI is gray.
6.3.3
Balance White Calculation Mode
a.
Highest Value - White Balance is normalized to the channel with the highest total value
b.
Red – White Balance is normalized to the Red channel total value
c.
Green – White Balance is normalized to the Green channel total value
d.
Blue – White Balance is normalized to the Blue channel total value
6.3.4
Pixel Correction Control
The command “DefectPixelCorrectionEnable “Enables the Defect Pixel correction algorithm. The
algorithm will correct up to 32 pixels in the sensor and up to 2 running pixels. The pixel correction
coordinates represent pixels of sensor’s visible ROI, therefore identifying the correct X and Y coordinate
should be done using default, full resolution image.
6.3.5
ExposureAuto & AutoGain Algorithm
Auto Exposure and Gain features are used to control the picture brightness by adjusting Exposure and
Gain values in automatic mode in order to reach desired brightness level. The algorithm calculates the
average picture intensiveness inside the defined ROI and tries to adjust it to desired brightness level. The
brightness is adjusted by increasing/decreasing exposure time and/or analog gain level.
There are three available modes for automatic brightness adjustment. Please see appendix no.1.
