Problems solved by technology

This means that when the user uses one of the cameras, there is an electrical connection between the data signal of the other camera sensor and the main processor at the same time. Although there is no real useful data on it, this electrical connection is in the initial state. And other uncertain states may have unpredictable effects on the sensors being used, the main processor, and peripheral devices related to the camera, such a

Embodiment Construction

[0026] The basic idea of ​​the present invention is: two camera sensors are connected by bridging, so that the two camera sensors are connected into a master-slave mode, their data signals are separated by a multiplexing switch, and different channels are opened according to the needs of the processor, so as to avoid When the user is using one of the cameras, the data signal of the other camera sensor is electrically connected to the main processor, so as to avoid mutual interference and reduce the occupation of main processor resources.

[0027] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be further described in detail by citing the following embodiments and referring to the accompanying drawings.

[0028] figure 2 It is a structural block diagram of the master-slave mode dual-camera processing device in the wireless terminal of the present invention. The master-slave mode dual-camera processing ...

Abstract

The invention discloses a method and a device for controlling two cameras in a master/slave mode in a wireless terminal, which are used for solving the technical problem in the prior art of mutual interference because a data bus is shared by the sensors of the two cameras. In the invention, the sensors of the two cameras are connected in the master/slave mode by a bridging method, and data signals thereof are separated through a multiplex switch; and different channels are opened according to the requirement of a processor; therefore, when one camera is used by a user, the electrical connection can be prevented from being formed between the data signal of the other camera and the main processor so as to avoid the mutual interference and reduce the occupation of the resource of the main processor.

Description

technical field [0001] The invention relates to the field of mobile communication, in particular to a method and device for controlling dual cameras in a master-slave mode in a wireless terminal. Background technique [0002] Mobile communication has now developed into the 3G era, and data services have been widely used in wireless terminals. The current wireless terminals are not only mobile phones, but are increasingly integrated with the Internet. On the 3G network, users can use videophone applications. This requires the wireless terminal to provide two cameras, one with relatively high pixel requirements for taking pictures, and the other with relatively low pixel requirements for self-portraits , such as video telephony, and the application of instant messaging systems. [0003] Each camera has its own independent sensor. The current common application scheme for two cameras is to directly connect the sensors of the two cameras to the main processor and share the data...
