This API is available on Firefox OS for privileged or certified applications only.


The flashMode property value is a string that defines how the flash, if any, is to be used. When set, its new value must be chosen from the list of options specified by  CameraCapabilities.flashModes.


var flash = instanceOfCameraControl.flashMode


Return a string representing the current flash mode. The default value is auto if the device has a flash, none otherwise.


var options = {
  camera: navigator.mozCameras.getListOfCameras()[0]
function onSuccess( camera ) {
  var capabilities = camera.capabilities;

  if (capablities.flashModes.indexOf('off') > -1) {
    camera.flashMode = 'off';

navigator.mozCameras.getCamera(options, onSuccess)


Not part of any specification; however, this API should be removed when the WebRTC Capture and Stream API has been implemented.
