Abstract

The embodiment of the present invention discloses a method for laser-assisted auto-focusing. The method includes: receiving an instruction to activate the laser-assisted focusing function to activate the laser-assisted focusing function; receiving a camera shooting instruction to start the laser-assisted focusing; Rotating the laser pulse transceiver, sending low-intensity laser pulses to the focus position of the camera through the laser pulse transmitter; receiving the reflected low-intensity laser pulses through the laser pulse receiver, according to sending and receiving the low-intensity laser pulses Calculate the distance between the smart terminal and the focus position of the camera; set the image distance of the camera and focus according to the distance from the smart terminal to the focus position of the camera. The technical solutions of the embodiments of the present invention can rotate the laser pulse transceiver according to the focus position required by the user, support laser-assisted auto-focus at different focus positions, improve the auto-focus accuracy of the smart terminal, and thereby improve user experience.

Description

Technical field [0001] The invention relates to the field of intelligent terminals, and in particular to a method and device for laser-assisted automatic focusing. Background technique [0002] With the popularization of mobile terminals, mobile devices such as mobile phones have become indispensable in life, and various additional functions of mobile devices have attracted more and more attention. In daily life, smart terminals have basically replaced card cameras. As people's photography tools. [0003] The autofocus of the smart terminal is different from the autofocus of the ordinary camera, and it cannot adjust the photosensitive element. Therefore, the auto focus function of the smart terminal is essentially based on the data calculation method of the image signal processor (ISP, Image Signal Processor), that is, when the viewfinder captures the original image, the image data is sent to the ISP as the original data. The ISP will analyze the raw data and check the density di...
