The program memory stores programs for controlling the general operation of the mobile communication terminal, and a program for synthesizing and editing an image taken from a dual camera, in particular, for performing the present invention, and an image taken by the dual camera in relation thereto. If necessary, the background image for editing and the image for editing are stored.

The controller 110 controls the overall operation according to the synthesis / editing and transmission from the photographing of the person or the subject of the dual camera of the mobile communication terminal. In addition, the controller 110 may include the data processor 120.

The first and second camera units 140 and 141, which are dual cameras, photograph a subject that is a photographer or a subject, and a camera sensor for converting the photographed optical signal into an electrical signal, and an analog image captured by the camera sensor. And a signal processor for converting the signal into digital data.

The image processor 150 processes an image photographed by the first and second camera units 140, and performs a function of displaying a preview of an image signal of a person or a subject photographed by the first and second camera units 140. The image signal of the eye, which is output from 140, is processed in units of frames, and the frame image data is output in accordance with the characteristics and size of the display unit 160. The frame image signal displayed on the display unit 160 restores the compressed or compressed frame image data to the original frame image data in a synthesized or edited state in a manner set by the control of the controller 110. The on-screen display data may be output according to the screen size displayed by the control of the controller 110.

The display unit 160 displays a preview state captured by the dual camera output from the image processor 150 or a synthesized or edited video signal of the captured image on a screen, and displays user data output from the controller 110. do. In this case, the display unit 160 may use an LCD. In this case, the display unit 160 may include an LCD controller, a memory capable of storing image data, and an LCD display device. In this case, when the LCD is implemented using a touch screen method, the LCD may operate as an input unit.

The key input unit 127 includes keys for inputting numeric and character information and function keys for setting various functions. According to an embodiment of the present invention, the first and second camera units 140 and 141 may be provided with input keys for selecting synthesis / editing, transmitting, and storing from an image by VT call.

2 is a flowchart for synthesizing / editing, storing, and transmitting an image after simultaneously photographing a photographer and a subject to be photographed through a dual camera according to an exemplary embodiment of the present invention.

The mobile communication terminal receives a key input from the controller 110 in the standby state of the 201 (203). If the input key through the key input unit 127 is a menu key (204), the controller 110 determines whether the dual cameras, that is, the first and second camera units 140 and 141, are in the photographing mode in step 207. In the dual camera shooting mode, the control unit 110 controls the first camera unit 140 and the image processing unit 150 and the display unit 160 in step 209 to capture the subject of the shooting target. It is shown on the display unit 160. Meanwhile, the second camera unit 141 photographs the photographer himself, and controls the image processor 150 and the display unit 160 to display the photographer before shooting through the display unit 160. When the photographing button is input in the key input unit 127 in step 211, the first and second camera units 140 and 141 capture and store a desired portion of the photographer and the photographing target at the same time in step 213.

However, if it is not the dual camera mode and the video call (VT call) mode in step 207, the controller 110 controls the RF unit 123 and the data processor 120 in step 217, and controls the display unit 160. While watching the video of the other party through the audio processing unit 125 is a voice call. In this case, if a selection is made in the key input unit 127 in step 219 to obtain a necessary portion of the counterpart image displayed during the call, the displayed image is stored in step 221. On the other hand, if the single camera mode in the process (223) (225), (227), and (229) through the process is a common way to shoot through one of the first and second camera unit 140, 141 consisting of dual Will be saved. The controller 110 confirms whether to synthesize the image obtained from the dual camera, the VT call, the single camera, or the like. When the synthesis is required in step 214, the controller 110 passes through the steps 222 and 230 when the video is additionally required from the dual camera, the VT call, and the single camera. Find and bring Step 231 separates the object from the image obtained for compositing. The separated object removes an unnecessary part of the background or synthesis for synthesis with other images of the whole image and leaves only the object to be synthesized. By discarding other parts, such as the background, which are not necessary for compositing by the object processing, compositing is performed. In step 233, a method of selecting a background image is also selected. If it is a selection for the background, the image for frame processing or a new background image is taken from the memory 130 in step 235, and if it is not selected for a separate background image, the background of the image previously obtained in step 237 is selected. Select one and use it. Like the background image selected in steps 239 and 241, the object separated in step 231 is synthesized and displayed on the display unit 160. The user checks in step 243 whether manual editing is required from the composite image displayed on the display unit 160. If the manual editing is required, in step 245, the photographer and the subject to be photographed are edited in various ways. In particular, the user can edit variously using the video of the VT call and the already stored video. In this case, when various photographs are obtained by combining photos 1 and 2 and obtaining photos 3 through compositing, the photos are edited by 1, 2 or 3 people from these photos 1,2,3 or edited by a third person. You can decorate with various videos. The edited image is displayed on the display unit 160 in step 247. If a transmission is selected in step 249, the controller 110 selects the RF unit 123 in step 257. A call path for calling the other party through the data processing unit 120 is formed and transmitted by sending 261. However, if a call path is formed from the call of the counterpart and the chat is performed in step 258, the character is inserted into the video edited in step 251 and transmitted in step 259. In addition, if you do not want to transmit immediately in step 249 and select "save" in step (253), the controller 110 controls the memory 130 to store the synthesized image.
