Problems solved by technology

The main principle of focusing is: traditional phase focusing uses the shaded pixels on the Complementary Metal Oxide Semiconductor (CMOS) for phase detection. Therefore, phase focusing requires relatively high light intensity, especially in dark vision. In bad environments, the focusing effect will be seriously affected. In addition, the phase focusing time is relatively long (generally takes about 0.8s), therefore, this focusing method cannot be well applied to dark vision environments and the focusing time is relatively long

Abstract

The embodiment of the invention discloses an image processing method which comprises the steps of: by utilizing a laser distance measuring sensor of a terminal, detecting a distance between a space position of each of N regions which are pre-divided in a preview image shot by a camera of the terminal and the camera so as to obtain N distance values, wherein the N is an integer greater than 1; determining out a minimum distance value in the N distance values; and using the region corresponding to the minimum distance value as a focusing region of the preview image. The embodiment of the invention further provides a terminal. By the image processing method and the terminal which are disclosed by the embodiment of the invention, rapid focusing can be carried out; moreover, the laser distance measuring sensor is adopted to carry out focusing, and thus, the focusing process is not influenced by light and focusing can be effectively carried out in a dark visual environment.

Description

technical field [0001] The present invention relates to the technical field of electronic equipment, in particular to an image processing method and a terminal. Background technique [0002] With the rapid development of information technology, terminals (such as mobile phones, tablet computers, etc.) are used more and more frequently, and more and more functions are integrated in the terminals. Taking pictures has become an important selling point of various mobile phone manufacturers. How to improve the effect of taking pictures and provide more differentiated functions has become the focus of each manufacturer's competition. [0003] In the prior art, when a camera is used to shoot a certain object, it is necessary to focus on the certain object, and then shoot after focusing. The main principle of focusing is: traditional phase focusing uses the shaded pixels on the Complementary Metal Oxide Semiconductor (CMOS) for phase detection. Therefore, phase focusing requires re...
