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


The focusMode property value is a string that defines which kind of focus mode the camera should use. When set, its new value must be chosen from the list of options specified by  CameraCapabilities.focusModes.


var focus = instanceOfCameraControl.focusMode


Return a string representing the current focus mode. The default value is auto or fixed (this depends on the device).


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

  if (capablities.focusModes.indexOf('macro') > -1) {
    camera.focusMode = 'macro';

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.
