Problems solved by technology

The functions of taking pictures and recording usually require the camera to shoot forward, which needs to be realized by the rear camera of the mobile phone. The video call function usually needs to capture the portrait of the caller himself, which needs to be realized by the front camera, and the same camera cannot be used to meet the two needs

Embodiment Construction

[0021] The present invention will be further described below in conjunction with the accompanying drawings and embodiments.

[0022] figure 1 It is a structural diagram of a hardware device applying the embodiment of the present invention. As shown in the figure, the device includes a processor 1, a front camera 2 and a rear camera 3. The processor 1 communicates with the I2C (Inter-Integrated Circuit, internal integrated circuit) bus 4 (the SCK and SDA pins of the I2C processor). The front camera 2 is connected to the back camera 3 (I2C is respectively connected to the SCK and SDA pins of the front camera and the back camera) for control. The PWDN (Power Down, low power enable) pin and Reset (restart) pin of the front camera 2 and the back camera 3 are connected with the GPIO (General Purpose Input / Output, general purpose input and output) pin of the processor 1. .

The invention realizes the different setting, controlling and switching the front pick-up head and the back pick-up head according to the different occasions and usages, and satisfies the requirement of the multimedia function for performing the photo taking,camera shot and the visual telephone and the like. The invention responds to the requirement of the user through the upper layer application program, transfers the bottom program to perform the corresponding powerup, initialization and switching operation, meanwhile realizes a plurality of multimedia functions. The invention has the beneficial advantages of realizing the setting, controlling andswitching the front pick-up head and the back pick-up head according to the different occasions and usages, conveniently taking photo, shooting and performing the video calling, capable of being convenient for the user to use.

Description

technical field [0001] The invention relates to a method for setting, controlling and switching front and rear cameras by a mobile terminal. Background technique [0002] With the development of personal mobile communication technology, 2.5G / 2.75G mobile terminals are becoming more and more popular, but 2.5G / 2.75G mobile communication networks can only provide voice services and data services, and cannot meet users' needs for video communication. [0003] After years of development, the domestic 3G network has gradually matured and will soon enter the commercial stage. The development and successful commercial use of 3G technology enables ordinary 3G terminal users to enjoy video call services conveniently and quickly. [0004] On the other hand, the development of mobile phone technology has made the functions of mobile phones more and more abundant, and the functions of taking photos and video cameras have become the standard configuration of ordinary terminals. [0005]...
