Abstract: The disclosure provides a method and apparatus for controlling dual cameras in a wireless terminal in a master-slave mode, in order to avoid interferences that may occur between the dual cameras due to sharing of data buses. In the disclosure, as the master processor uses a set of resources to control the two cameras, the resources of the master processor may be saved which otherwise will be occupied by the dual cameras, the dependency of the cameras on the master processor is reduced, so that the master processor may release more resources for other peripherals or other tasks. As the multiplexer switch isolates signals of the two camera sensors in a relatively thorough way, mutual interferences between the two cameras may be avoided and electromagnetic interferences may be decreased.
