Abstract

The invention discloses a focusing system, method and device, and belongs to the technical field of communication. The focusing system comprises a sensor, a transmitting plate and a focusing module, signal transmitting units which are arranged in an array mode are arranged on the transmitting plate, and the frequencies of transmitting signals transmitted by the signal transmitting units are different, wherein the signal emission unit is configured to send an emission signal to a first surface of a shooting object after a camera is started; the sensor is configured to determine a measurement distance between each position point of the first surface and the camera based on the transmitting frequency of the transmitting signals and the reflecting frequency of the reflecting signals after receiving the reflecting signals corresponding to the plurality of transmitting signals; and the focusing module is configured to focus the shooting object according to the plurality of measurement distances. According to the invention, the focusing accuracy can be improved on the basis of rapid focusing.

Description

technical field [0001] The present application belongs to the technical field of communication, and in particular relates to a focusing system, method and device. Background technique [0002] With the continuous development of science and technology, electronic devices (such as mobile phones, tablet computers, etc.) have gradually become an indispensable tool in people's life and work. [0003] In practical applications, cameras on electronic devices have more and more camera functions, and consumers have higher and higher requirements for camera experience. This poses a huge challenge to the functions, performance and effects of cameras. The most important thing in the camera is the 3A (autofocus (Auto Focus, AF), automatic exposure (Automatic Exposure, AE) and automatic white balance (Automatic white balance, AWB)) function, in which AF plays a vital role, is The premise of all photo effects, so AF accuracy is very important. There are three methods of AF in the industr...
