Exposure

This property page is used to select the properties specifying the display features of the video.



Select from the following options:

Brightness

Move the slider to adjust the brightness (black level) of the video. Note that this option is available only for the cameras that support the software brightness control.. Equivalent to the Brightness property.

Shutter

Move this slider to adjust the integration time of the incoming light. Note that this option is available only for the cameras that support the software shutter control. Equivalent to the Shutter property.

   
Gain

Move this slider to adjust the camera circuit gain control. Note that this option is available only for the cameras that support the software gain control. Equivalent to the Gain property.

Iris

Move this slider to adjust the iris (mechanical apperture) of the camera lens. Note that this option is available only for the cameras that support the software iris control. Equivalent to the Iris property.

Gamma

Move the slider to adjust the gamma level of the video. The gamma correction modifies an image by applying standard, nonlinear gamma curves to the intensity scale. To lighten an image and increase the contrast in its darker areas, increase the gamma by moving the slider to the right. To darken the image and emphasize the contrast in the lighter areas, decrease in the gamma by moving the slider to the left. Note that this option is available only for the cameras that support the software gamma control. Equivalent to the Gamma property.

Sharpness

Move the slider to adjust the sharpness of the video. Note that this option is available only for the cameras that support the software sharpness control. Equivalent to the Sharpness property.

Optical Filter

Move the slider to adjust the optical filter of the camera. Depending on the camera model, it can control the mechanical optical filter or the electronic filter. For Bayer cameras this feature will typically allow for changing the color pattern of the raw output data. Note that this option is available only for the cameras that support the software sharpness control.. Equivalent to the OpticalFilter property.

Each of the sliders has a corresponding check box On located on the left and Auto located on the right. If an On box is unselected, the corresponding feature will be disabled. If an Auto box is enabled, the camera supports an automatic mode for the corresponding feature. Checking the box will put the camera to the continuous automatic control of the feature, unchecking it will restore the manual control.

Auto Exposure Reference

Use this option to control the AE mode of the camera. When the auto exposure mode is activated, the camera will automatically control the exposure by keeping Shutter, Gain and/or Iris at optimal levels. The reference value for auto exposure can be adjusted by moving the slider next to the check box. Both options are available only if the currently selected camera supports auto exposure control. Equivalent to the AutoExposure and AutoExposureRef properties.
