Abstract

The invention discloses a method and device for reducing camera power consumption, and a mobile terminal, wherein the method comprises following steps of receiving a photographing preview instruction; detecting environment brightness and a focusing triggering condition; judging whether the environment brightness change exceeds an appointed threshold value or not and whether the focusing triggering condition is satisfied or not; when the environment brightness change does not exceed the appointed threshold value and the focusing triggering condition is not satisfied, locking an AE / AF function and a camera image signal processor ISP; and otherwise, unlocking the AE / AF function and the camera image signal processor ISP, and returning to the step of detecting the environment brightness and the focusing triggering condition. According to the method, the device and the mobile terminal, through detecting external environment factors such as the environment brightness and the focusing triggering condition, the AE / AF is dynamically locked or unlocked; AE / AF algorithms are reduced; the operation time of the camera image signal processor ISP is reduced; the camera power consumption is reduced; and the electric quantity of the mobile terminal is reduced and the battery duration of the mobile terminal is improved.

Description

technical field [0001] The present invention relates to the technical field of communication of mobile terminals, in particular to a method and device for reducing camera power consumption and a mobile terminal. Background technique [0002] With the advent of the information technology era and the continuous improvement of communication network technology, mobile terminals (or mobile phones) have become one of the most common communication tools at present. Mobile terminal products have become necessary living tools for more and more consumers because of their small size, convenient portability, complete functions and increasingly low prices. [0003] However, due to the rapid development of electronic technology, mobile terminals are developing towards larger screens and multi-core processing. Various terminal applications and online connection anytime and anywhere will pose challenges to the continuous power supply of mobile terminals. In particular, the camera function ...
