Hereinafter, embodiments of the present invention will be described in detail with reference to the accompanying drawings.

FIG. 1 is a block diagram of an external configuration of a video terminal for next generation mobile communication according to the present invention. In the figure, "1" is a camera, "2" is an antenna, "3" "5" is a power button, "6" is a send / end button, "7" is an up button, "8" is a down button, A volume button, a brightness button 10, a saturation button 12, a contrast button 12, a hue button 13, , "14" indicates a microphone, and "15" indicates a status display device, respectively.

As shown in the figure, in an example of the present invention, a small camera 1 for photographing an outside object, a person (caller, etc.) and the captured image at the top of the image terminal, An antenna 2 for receiving a video signal (in the drawing, an antenna indicates a pulled-in state, and is configured to be used when the terminal is used), a speaker 4 for outputting a reception voice of the other party, And an image display device 3 for outputting a received image of the person. Meanwhile, a method of displaying the state of the terminal by dividing the image display device 3 may be used. However, in an embodiment of the present invention, in order to effectively display an image on the image display device 3, And a status display device 15 for outputting a status and a screen status. As described above, in the present invention, the image display apparatus 3 for outputting images and the status display apparatus 15 for displaying the status of the terminal are configured separately from the conventional voice terminals.

On the other hand, in the embodiment of the present invention, a POWER button 5 for turning on / off power to the lower end of the image terminal, a control signal and a telephone number are transmitted to instruct a call connection, A Send / End button 6 for indicating termination of the call, a Volume button 9 for adjusting the volume, a Brightness button 10 for adjusting the brightness of the image screen, A Saturation button 11, a Contrast button 12 and a Hue button 13 for adjusting the color, and a button for turning on the corresponding function of each function button A down button 8 for downwardly depressing corresponding function of each function button and a microphone 14 for receiving a voice of a caller.

At this time, each of the function buttons is arranged in each row on both sides of a center where 12 dial buttons and function keys are arranged in 3 rows and 4 rows.

At this time, the Send / End button 6 is pressed once to transmit a control signal and a telephone number to make a call connection, and to terminate the call when the call is once again pressed. As described above, according to the present invention, the Send / End button 6 is configured as one unit to make the user more convenient to make a call.

Further, the present invention is more effective in the case of constituting a folding type video terminal which is coupled with a hinge between a housing at an upper end and a housing at a lower end.
