    determine that a change in the monitored ambient light level is above a first threshold; and

    in response to the determination, trigger image capture by automatically sending a signal to capture an image using the camera, if the acceleration of the camera is below a second threshold;

    wherein the controller is configured to trigger image capture using the camera in response to detecting a change in average light level within a given time period.
