Description of drawings

FIG. 1 is a schematic diagram of the external structure of an embodiment of the mobile terminal described in the present invention;

FIG. 2 is a schematic diagram of the circuit structure of an embodiment of the mobile terminal described in the present invention.

Detailed ways

The technical scheme of the utility model is to send the image received by the mobile phone to the display screen of the computer through the wired or wireless interface, and the user watches the transmitted image through the display screen of the computer.

The mobile terminal described in the technical solution of the utility model is a third-generation mobile terminal, which has a videophone function. In terms of hardware structure, the mobile terminal should be equipped with a built-in or external camera and an image output interface. Wherein, the camera is used for the user to take his own image and send the image to the other user, and the image can also be displayed on the display screen of the user terminal itself. The image of the other party in the video call received by the mobile terminal can be output to the display screen of the mobile terminal for display after being processed by the multimedia processor, and can also be output to the display screen of the computer through the image output interface for display, so as to realize the possibility of a large screen. Video phone function.

The technical scheme of the utility model will be further described below in conjunction with the accompanying drawings and embodiments.

As shown in Figure 1, it is a mobile terminal with a videophone function, which has a multimedia processor, a microphone, a speaker, a wireless communication module, etc., and a camera 2 and a display are arranged on the same surface of the mobile terminal housing 1 Screen 3, the camera 2 is used to capture the image of the user, and send the image to the multimedia processor, after being processed by the multimedia processor (such as compression, merging with the sound signal, etc.), it is sent to the other party of the video call through the wireless communication module . Of course, the camera 2 can also use an external camera to increase the flexibility of the mobile terminal. In addition to providing the conventional functions of the mobile terminal, the display screen 3 can also receive and display images output by the multimedia processor. The images can be the images of the local user or the image of the other party in the video call.

As shown in Fig. 2, the mobile terminal with videophone function of the present invention also includes an output interface 5 connected with the output end of the multimedia processor 4, and the output interface 5 is used to establish a connection with a computer. When the video call is in progress, the multimedia processor 4 processes the received information of the other party of the video call (for example, separates the audio from the video, decompresses the image, etc.), and outputs the processed image and sound. The image output by the multimedia processor 4 can be sent to the computer through the output interface 5, and displayed on the display screen of the computer, making full use of the large area and high resolution of the computer display screen, thereby realizing a large-screen video call, improving user's visual experience. The output interface 5 may be one of a Bluetooth interface, an infrared interface and a USB interface. When a Bluetooth interface or an infrared interface is used, the advantages are good mobility and flexible and convenient use; when a USB interface is used, the advantages are fast transmission speed and good stability. Of course, in order to have multiple advantages at the same time, multiple output interfaces can also be used at the same time.

During the user's conversation, the user can control the output terminal of the multimedia processor 4 to output the image to the display screen 3 of the mobile terminal through an input command, or output the image to the display screen of the computer through the output interface 5, thereby realizing the display on the mobile terminal. Toggle between display 3 and computer display. The image signal can also be output to the display screen 3 of the mobile terminal and the display screen of the computer at the same time as required, so that images can be displayed simultaneously on the display screen 3 of the mobile terminal and the display screen of the computer.

Taking the bluetooth interface as an example to illustrate the switching process of the display mode of the display screen of the mobile terminal and the display screen of the computer. When the user conducts a video call in the display mode of the mobile terminal display, the output terminal of the multimedia processor 4 outputs an image signal to the display screen 3 of the mobile terminal. When the user wants to experience the video call on the large screen, start the bluetooth search, after searching for a matching computer with a bluetooth interface, establish a connection with the computer, the user inputs a switching command, and after the multimedia processor 4 receives the switching command, Its output end sends the image signal to the bluetooth interface, that is, through the bluetooth interface, it is sent to the display screen of the computer for display. It is also possible to automatically start the Bluetooth search and establish a connection with a matching computer after the user outputs the switching command, and the multimedia processor 4 sends the image signal to the Bluetooth interface to realize the switching of the display. The user can also switch the image to be displayed on the display screen of the mobile terminal by inputting the switching command again.

In order to switch more conveniently, a switch 6 can be set between the output terminal of the multimedia processor 4 and the display screen 3 of the mobile terminal and the output interface 5. The switch 6 can be set on the housing 1 of the mobile terminal, and the user can It is convenient to switch between the two display modes of the display screen 3 of the mobile terminal and the display screen of the computer by flipping the switch 6 .

The mobile terminal described in the utility model includes a mobile phone, and also includes other mobile terminals such as a PDA (Personal Digital Assistant) with a communication function.

It should be understood that those skilled in the art of the present invention can make corresponding equivalent changes or replacements according to the technical solutions and concepts of the present invention, and all these changes or replacements should belong to the appended rights of the present invention. the scope of protection required.
