Abstract:
An electronic device controlled via a non-contact gesture is disclosed. The electronic device includes multiple infrared sensing units, when a gesture is passing over the infrared sensing units, status of level(s) outputted by output terminals of the infrared sensing units may be changed; a logic circuit, with its multiple input terminals being respectively connected to the output terminals of the multiple infrared sensing units, configured to, when there is a change in the levels outputted by the infrared sensing units, generate and output in interrupt signal; a processor, coupled respectively to the output terminals of the multiple infrared sensing units, and connected to the output terminal of the logic circuit, and configured to receive the interrupt signal and, when each time receiving the interrupt signal, acquire the level status at the output terminals of the infrared sensing units and save the level status as a set of level status data.
Abstract:
A method for adjusting screen brightness and system thereof are described. The method comprises: acquiring an attribute parameter of a screen image and a current screen brightness in a smartphone; comparing the attribute parameter of the screen image of the smartphone to the current screen brightness; and decreasing a screen display brightness when the attribute parameter is greater than the screen brightness; and increasing the screen display brightness when the attribute parameter is less than the screen brightness.
Abstract:
A mobile terminal and a mistaken dialing preventing method thereof are provided. The mistaken dialing preventing method is based on a mobile terminal comprising a distance sensor and a touch screen, and comprises: when the touch screen is not locked and is displaying a dial plate icon, activating the distance sensor to detect whether there is an obstruction within an effective distance above the touch screen; if there is an obstruction, then detecting by the distance sensor a current distance between the obstruction and the touch screen of the mobile terminal; and if the current distance is smaller than a preset critical distance threshold, then controlling the touch screen to not display the dial plate icon and deactivating the distance sensor by the mobile terminal. In this way, the present disclosure can automatically deactivate the call program of the smartphone to absolutely prevent mistaken dialing with a very satisfactory effect.
