Abstract: The embodiments of the present application provide a wireless charging method and system, and a mobile terminal. The wireless charging method includes: activating a wireless charging function by a first mobile terminal and a second mobile terminal; determining that the first mobile terminal is a wireless charging sender, and the second mobile terminal is a wireless charging receiver; and performing a wireless charging on the second mobile terminal by the first mobile terminal. The embodiments of the present application solve the problem that the power is insufficient in emergency situations. In addition, the operation is simple and the usage limitations are reduced.

Abstract: The embodiments of the present invention provide a method and an apparatus for controlling a work mode, and an electronic device, wherein the method comprises: capturing, by an electronic device, at least two images; calculating a difference between the at least two images; and comparing the difference between the at least two images with a predetermined first threshold, and determining whether to switch the work mode of the electronic device according to a comparison result. Thus the electronic device automatically performs the mode switching without influencing the user's shooting experience.

Abstract: A device and method is provided for controlling a electronic device that includes a display device arranged on a first side of the electronic device, and a first optical device configured to capture optical data. An object is placed over the first optical device so as to at least partially block ambient light from the first optical device, and based on data captured by the first optical device, an input to the electronic device is assigned to the detected object. The assigned input is equated to a predetermined function of the electronic device.
