Abstract

Disclosed is an electricity-saving device and a method for the camera of a multimedia mobile phone; the electricity-saving device is characterized in that the main board of the mobile phone includes a baseband and a low-dropout linear regulator; the fourth output end of the baseband is connected with the turn-off pin of the internal power supply of the camera; the second output end of the baseband is connected with the digital voltage pin of the camera; the fifth output end of the baseband is connected with the input end of the low-dropout linear regulator; the first output end of the low-dropout linear regulator is connected with the analog voltage pin of the camera; the second output end of the low-dropout linear regulator is connected with the digital I / O port voltage pin of the camera. The electricity-saving method is realized through the software. The electricity-saving device and the method can enable the current consumption of the camera of the multimedia mobile phone to be about 20 uA.

Description

technical field [0001] The invention relates to a mobile communication terminal, in particular to a power saving device and method for a camera of a multimedia mobile phone. Background technique [0002] With the development of mobile communication, mobile phones have increasingly powerful functions and more and more diversified products. The camera is an indispensable part of mobile phones in this period, especially multimedia mobile phones. According to the resolution of the camera of the multimedia mobile phone, it is divided into: 100,000, 300,000, 1.3 million, 2 million, 3 million pixels or even higher 5 million pixels; according to the lens type of the camera, it is divided into: CMOS lens, CCD lens Wait. Most of the multimedia mobile phones currently on the market have cameras with 300,000 / 1.3 million pixels and CMOS lenses. Rich and colorful mobile phone cameras are a challenge to the power consumption of mobile phones. Especially when the battery capacity of mobi...
