Abstract: A night-light control method in an electronic device comprises controlling a photosensitive sensor to detect a light intensity value and controlling an acceleration sensor to detect an acceleration value of the electronic device and thus movement. Acquiring the acceleration value from the acceleration sensor when the acquired light intensity value is in the first preset light intensity range; determining whether the acquired acceleration value is in a preset acceleration range and controlling an infrared sensor to detect whether a user of the electronic device is moving when the acquired acceleration value is in the preset acceleration range. A display unit of the electronic device is controlled to emit light or control a light emitting unit of the electronic device to emit light when the user of the electronic device is moving.

Abstract: A method for controlling a flash lamp of a camera to provide supplemental light during image-capturing is disclosed. The flash lamp includes a lamp and a position adjusting unit, the lamp being able to track a moving target object in addition to being able to apply spotlighting or wide angle illumination of the object. The method acquires a first brightness value surrounding a target object from a photosensitive unit, compares the value with a preset value and turns on the lamp when the value is less than the preset value. The camera can detect whether the target object is moving; and the lamp can be controlled to move (by the position adjusting unit) to track the moving target object and maintain illumination of it for the image-capture.
