The invention relates to a flashlight, an electronic device with the flashlight and a control method for the flashlight. The method comprises the steps of: acquiring the brightness of the light of the external environment of the target object detected by a photosensitive sensor; comparing the brightness of the acquired light with a preset brightness value; determining that the brightness of the acquired light is smaller than the preset brightness value Timely control the camera unit to take pictures of the target object and control to turn on a flashlight to supplement light to the target object; control the camera unit to detect whether the target object moves; and control the target object through a position adjustment unit when it is determined that the target object moves The flash moves to track the target object. The present invention is simple to implement, and the position adjustment unit controls the movement of the flashlight to track the target object to be photographed, and produces a better supplementary light effect on the target object.
Description
technical field [0001] The invention relates to the field of consumer electronic products, in particular to a flashlight, an electronic device with the flashlight and a method for controlling the flashlight. Background technique [0002] At present, when an electronic device with a camera function, such as a mobile phone, takes pictures, because the shooting environment is dark, in order to take pictures clearly, it is necessary to turn on the flashlight function. However, when the photographed target object moves, the flashlight cannot track the photographed target object, which affects the effect of the flashlight for supplementing light on the target object. Contents of the invention [0003] In view of the above, it is necessary to provide a flashlight, an electronic device having the flashlight, and a flashlight control method to solve the above-mentioned existing problems. [0004] A flashlight module, including at least one flashlight, the flashlight is used to sup...
