IDS Software Suite 4.96.1

On this tab you can set the sensor gain parameters for your uEye camera (see also Gain and offset).

Master gain

The following functions control the analog image signal gain and the black level. The analog adjustments are made directly in the sensor, which achieves better results than image adjustments via software.

•Gain [0 ... 100]
Gain for overall image brightness. Some camera models have no master gain.
Master gain = 100 means maximum gain; the actual factor is displayed. A gain factor of 1x disables master gain. The maximum possible gain factor depends on the model you are using.

•Auto
Select this check box to activate the automatic gain control function. Manually changing the master gain setting disables the "Auto" function.

•Gain boost
Additional analog camera hardware gain. The gain factor ranges between 1.5x and 2x, depending on the camera model.

•Black level (offset) [0 ... 255]
Offset for the black level of the sensor signal. The sensor adjusts the black level of the pixels automatically by default. High gain may offset the black level. Only an additive offset is possible (increase of the black level).

•Auto
The black level is automatically corrected by the sensor (recommended).

Color gain

You can fix a setting (in kelvins) for the color temperature of an image when you are using a color camera. The function will use the sensor's hardware gain controls for the setting, as far as possible. In addition, you can choose between different color spaces. A specific color temperature will result in slightly differing RGB values, depending on the selected color space.

•White balance

oManual
Set the RGB gains manually.

oAuto (grey world)
Enable the AWB (auto white balance) function based on the grey world algorithm.

oAuto (Kelvin)
Enable the AWB (auto white balance) function based on the Kelvin color temperatures.

oDefault gains
Default gain values for this camera model.

osRGB D50
sRGB (standard RGB) color space with a white point of 5000 kelvins (warm light)

osRGB D65
sRGB (standard RGB) color space with a white point of 6500 kelvins (mid daylight)

oCIE RGB E
CIE-RGB color space with standard illumination E

oECI RGB D50
ECI-RGB color space with a white point of 5000 kelvins (warm light)

oAdobe RGB D65
Adobe RGB color space with a white point of 6500 kelvins (mid daylight). The Adobe RGB color space is larger than the sRGB color space, but not all devices can render it.

•Presets
This selection box offers several presets for common illumination types.

•Temperature (Kelvin)
Here, you can set a color temperature value directly.

For color cameras, the following functions control the analog gain for the RGB color channels. The analog control is performed in the sensor (except color models UI-122x/UI-322x/UI-522x) and achieve better results than software based image correction.

•Red gain [0 ... 100]
Amplifies the red color values

•Green gain [0 ... 100]
Amplifies the green color values

•Blue gain [0 ... 100]
Amplifies the blue color values

Gamma

•On
This function activates the gamma function and sets the factor for the gamma curve. The gamma function emphasizes dark image areas according to a non-linear curve. If you are using a uEye camera with activated hardware color calculation, the gamma curve is calculated in the camera. In all other cases, the gamma curve is calculated in the PC.

•Hardware sensor gamma
UI-122x/UI-322x/UI-522x or UI-124x/UI-324x/UI-524x or UI-125x/UI-325x/UI-525x only: This option enables gamma correction by the hardware, using a fixed factor.
