Hereinafter, a video recording method of a mobile communication terminal according to the present invention will be described in detail.                     

3 is a diagram for explaining a simultaneous recording method when recording a video according to the present invention, the screen 300 of the video recording program configuration is a program title bar 310 to display the currently running program, shooting through the camera Shooting target display window 320, zoom 332, brightness 334, the image reversal 336 and the background sound 338 to display the target to be displayed, the icon bar 330 and the title bar 310 It consists of a recording icon 312 provided on one side of.

Accordingly, the user selects a video recording function key or a video recording menu so that the video recording program is read from the program storage unit 244 of the memory 240. When the video recording program is executed, the function icons 332 and 334 are executed. 336, 338, and the recording icon 312 are selected and set, and then photographing is performed.

4 is a flow chart of a simultaneous recording method when shooting a video according to the present invention, it turns out that the subject is a control unit of a mobile communication terminal.

As shown in FIG. 4, in step S11, it is determined whether there is a key input from the user through the key input unit 230. As a result of the determination in step S11, if there is no key input, step S11 is repeated until there is a key input, and if there is a key input, the flow advances to step S13 to determine whether or not a simultaneous recording video recording command. As a result of the determination in step S13, if it is not a simultaneous recording video recording command, the flow advances to step S23 to execute a command corresponding to a key input. In the case of a video recording program execution command, the flow proceeds to step S15 where an arbitrary background sound is selected. Judge

As a result of the determination in step S15, if a random background sound is selected, the flow advances to step S17 to read the selected background sound from the data storage unit 244, outputs it to the speaker 254, and then proceeds to step S19. If it is not selected, the process proceeds directly to step S19 to receive a video signal and an audio signal from the camera 282 and the microphone 252 and to store it in the data storage unit 244.

After the shooting is finished, the video signal and the audio signal stored in step S21 are synchronized and stored as one file.

On the other hand, the recording function and the background sound function will be able to be selected even during shooting, the voice signal processing unit 250 will be able to use the voice modulation function when shooting by adding a voice modulation function. In addition, commands input from the user may be input through the recording menu by adding a recording menu to a basic menu as well as an input using a function key.

The video recording method of the mobile communication terminal of the present invention is not limited to the above-described embodiment, and can be modified in various ways within the scope of the technical idea of the present invention.

According to the video recording method of the mobile communication terminal of the present invention as described above, the simultaneous recording function can be selected during video recording, so that the video and the voice including the ambient sound can be stored together, and the video is recorded in the memory of the mobile communication terminal. By simultaneously playing the pre-stored sound file is used as the background sound of the image to be photographed, there is an effect that can create a variety of atmosphere due to the background sound.
