Patent ID: 7099987

Claim:
A mobile terminal having a switching function, comprising: a dual interface means connected to an external device through a communication line, configured to multi-switch data according to a microcontroller unit (MCU) selection signal and a digital signal processor (DSP) selection signal; an image processing means configured to obtain external image data, digitalize the image data and output the digitalized data to the dual interface means; a signal processing means configured to activate the MCU selection signal or the DSP selection signal, send the data to the external device through the dual interface means, receive the data from the external device through the dual interface means and processing the data; and a memory means configured to store or output the data according to control of the image processing means or the signal processing means, wherein the dual interface means includes: a connector connected to the external device through the communication line, configured to provide an interface: a first dual single pole single throw (SPST) connected to a first USB line of the communication line through the connector, configured to provide a data oath to the signal processing means when the MCU selection signal is activated and provide a data path to the image processing means when the DSP selection signal is activated, a second dual SPST connected to a second USB line of the communication line through the connector, configured to provide a data path to the signal processing means when the MCU selection signal is activated and provide a data path to the image processing means when the DSP selection signal is activated.
