VideoDeviceController.Brightness | brightness property

Gets or sets the brightness level on the camera.

Syntax


var brightness = videoDeviceController.brightness;

Property value

Type: MediaDeviceControl

A MediaDeviceControl object that provides methods to get and set the brightness.

Remarks

For NTSC sources, brightness is expressed in IRE units multiplied by 100. For non-NTSC sources, the units are arbitrary, with 0 representing blanking and 10000 representing pure white.

Examples

The following example shows how to get the value of this property.


// Get the step size, minimum value, and maximum value of the brightness property to set
// values on a slider control.

function setBrtSlider() {
    var videoDev = null;
    var bValue = null;

    var mediaDevice = new Windows.Media.Capture.MediaCapture();
    videoDev = mediaDevice.videoDeviceController;
   
    if (videoDev.brightness.capabilities.step !== 0)
    {
        bValue = videoDev.brightness.tryGetValue();
        document.getElementById("slBrt").value = bValue.value;
        document.getElementById("slBrt").min = videoDev.brightness.capabilities.min;
        document.getElementById("slBrt").max = videoDev.brightness.capabilities.max;
        document.getElementById("slBrt").step = videoDev.brightness.capabilities.step;
    }
}
