IDS peak 2.8.0 / uEye+ firmware 3.33

This chapter contains the descriptions of all supported features from the Analog Control category.

The functions in this chapter describe how to control the properties of an image such as BlackLevel, Gain, Gamma and white balance.

Calculation of the pixel value

Using the BlackLevel, Gain and Gamma functions, the original pixel value Y is converted to a new pixel value Y'. If a digital "Gain" is applied, for the new pixel value Y' the following applies:

Manual white balance

Some color cameras control the gain of each color channel independently. In this case, you can use the red, green and blue gain function for manual white balancing. You define the channel to be amplified via the GainSelector.

Automatic functions

With the automatic functions GainAuto, BlackLevelAuto and BalanceWhiteAuto you automatically adjust the camera once (Once) or continuously (Continuous).

Most of the automatic functions have three possible values:

•Off: The automatic adjustment is deactivated, you can control the adjustment by yourself.

•Once: The automatic adjustment is performed once by the camera. The function is automatically set to "Off" after the adjustment.

•Continuous: The automatic adjustment is performed continuously by the camera. For this, the target values are supplied by the functions involved (e.g. Gain and/or Gamma).

IDS functions that extend the SFNC standard:

ADCGainCorrection: With ADCGainCorrection you activate/deactivate a predefined correction value for the gain to use the full dynamic range of the sensor.

Explanation of the LogMode

The LogMode is a special mode of some uEye camera models in which a threshold defines at which point the linear sensitivity pass over into a logarithmic characteristic. At very short exposure times (less than 0.1 ms) there may occur e.g. so-called crosstalk effects in the global shutter mode, which have the effect that the image content appears brighter in the vertical from top to bottom. This effect can be avoided by the LogMode.

You can either use the LogMode with "Auto" or "Manual" setting. Only in case of "Manual", you will use the settings in LogModeManualValue and LogModeManualGain
