Therefore, detailed description thereof will be omitted.

The controller 290 of the control mobile communication terminal (hereinafter, referred to as a control terminal) 200 according to the present embodiment performs the overall control operation of the control terminal 200. In addition, the controller 290 according to the present invention communicates with the photographing terminal 100 through the near field communication unit 220. In addition, the control unit 290 of the control terminal 100 according to the present invention includes a remote photographing unit 292.

The remote photographing unit 292 receives image data from the photographing terminal 200 and displays the image data on the display unit 250. The remote photographing unit 292 receives an image control command and a storage command through the key input unit 160, and sends the image data to the photographing terminal 100. send. In addition, during the image capturing, digital audio data (hereinafter, referred to as acoustic data) is generated through the audio processor 240 and transmitted to the photographing terminal 100, or the image data transmitted from the photographing terminal 100 and the control terminal 200. The video is generated using the sound data transmitted from the audio processor 240.

The control terminal 200 having such a configuration is used to remotely control the photographing terminal 100 and to photograph an image. That is, the control terminal 200 controls so that various effects are applied to the preview image generated by the photographing terminal 100 and remotely controls the photographing terminal 100 so as to photograph at a moment desired by the user.

Next, a remote photographing method using a mobile communication terminal according to the present invention will be described in detail with reference to the following embodiments. From the following description of the remote photographing method, the configuration of each of the aforementioned mobile communication terminals will also be clearer.

3 is a flowchart schematically illustrating a still image photographing process according to the remote photographing method of the present invention, and FIG. 4 is a flowchart schematically showing a still image photographing process of a photographing mobile communication terminal according to the present invention.

1 to 4, first, a short range communication connection request is transmitted from the control terminal 200 through the Bluetooth module 122 in step S20. When the receiving terminal 100 receives the short-range communication connection in step S21, the terminal 100 for photographing and the control terminal 200 communicate with each other by the local area network 120, that is, the Bluetooth module 122. It becomes possible.

Next, in step S22, the user requests a remote photographing control from the control terminal 200. The remote photographing control request according to the present embodiment means that the control terminal 200 requests all control rights for photographing the photographing terminal 100. Therefore, when the user manipulates the photographing terminal 100 to approve the remote photographing control request in step S23, the photographing terminal 100 performs the photographing process by a control command transmitted from the control terminal 200 in a subsequent process. do. On the other hand, in the case that the shooting terminal 100 does not approve the remote shooting control request, in step S231 the control terminal 200 cannot control the shooting process of the shooting terminal 100, so the control unit 190 of the shooting terminal 100 ) Will execute the commands that are entered later.

The photographing terminal 100, which has approved the remote photographing control request, drives the camera unit 130 for photographing in step S24. The image signal captured by the camera unit 130 is converted into image data by the image processor 150. Accordingly, the display unit 150 receives the image data from the image processor 150 and displays the preview image on the screen in real time.

At the same time, in step S25, the image transmitter 190 receives image data from the image processor 180 and transmits the image data to the control terminal 200 in real time using near field communication.

After receiving the image data, the remote photographing unit 292 of the control terminal 200 converts the image data to be displayed on the display unit 250 of the control terminal 200 in step S26, and then transmits the image data to the display unit 250. Display the preview image. In this case, the image data transmitted from the photographing terminal 100 is continuously transmitted to the control terminal 200 unless the remote photographing control is terminated. Accordingly, the preview image displayed on the display unit 250 of the control terminal 200 also displays the same image as the image captured by the photographing terminal 100 in real time.

Here, in the present embodiment, since the preview image of the photographing terminal 100 is transmitted to the control terminal 200 and then displayed on the display unit 250 of the control terminal 200, the preview image and the control image displayed on the photographing terminal 100 are used. The preview image displayed on the terminal 200 may be displayed with a slight time difference. However, since this is a slight difference, it will be described on the assumption that the preview image is displayed on both terminals 100 and 200 in real time.

 If the user wants to modify the preview image while the preview image is displayed on the control terminal 200, the user inputs an image control command through the control terminal 200 and transmits it to the photographing terminal 100 in step S27. The image control command includes all image control commands applicable to the photographing terminal 100. That is, to give a preview image a specific effect (eg monotone, sepia, invert shadow, emboss, fog, brightness, white balance, etc.), the size of the preview image (eg zoom in, zoom out, etc.), resolution, type of capture (eg Includes commands that can modify the outer frame settings, whether the flash is fired, continuous shooting, upside down, etc.).

Meanwhile, the method of inputting an image control command is not limited to one particular method, and various methods may be used in combination. For example, a method of displaying an item related to image control in a menu of the control terminal 200 step by step so that a user may sequentially enter and select a desired image control command. As another example, a method of separately setting an image control key (not shown) and displaying a screen for inputting an image control command when a corresponding key is input may be used so that a user inputs an image control command.

When the image control command is transmitted to the photographing terminal 100 in step S27, the image control unit 194 of the photographing terminal 100 receives the same and performs the corresponding control command in step S28. For example, when the user selects and transmits a preview image up and down command from the control terminal 200, the image controller 194 of the photographing terminal 100 inverts and displays the top and bottom of the preview image input according to the command. . At this time, since the preview image of the photographing terminal 100 is continuously transmitted to the control terminal 200, the preview image displayed on the control terminal 200 is also displayed inverted up and down. Therefore, the user can easily check how the preview image to which the image control command is applied is only seen through the control terminal 200.

When the user wants to take a still image in the process of checking the preview image through the control terminal 200, the user operates a key input unit 260 of the control terminal 200 to request a still image shooting, thereby controlling The terminal 200 transmits a still image shooting request signal to the shooting terminal 100 in step S29.

The terminal 100 for receiving the still image shooting request signal extracts and temporarily stores a frame of the image currently displayed on the preview image in step S30. In this case, the temporarily stored image frame is preferably stored in an internal buffer memory (not shown) of the controller 190, but is not limited thereto.

Subsequently, the photographing terminal 100 that temporarily stores the still image in step S31 transmits the temporarily stored still image to the control terminal 200, and the control terminal 200 that receives the temporary image is displayed on the display unit. Marked at 250. Accordingly, the user can immediately check how the captured still image is displayed through the control terminal 200.

After the user checks the still image and transmits a storage command in step S33, the terminal 100 for photographing stores the temporarily stored still image in the storage unit 150 in step S34. The file name of the still image stored in this process may be automatically assigned by the controller 190 or received and input by the user.

Here, although not shown, if the user does not want to save in step S33, the user transmits a still image delete command, and the receiving terminal 100 receives the deleted after the temporary image is stored temporarily, again In operation S25, the preview image is transmitted to the controller terminal.

Meanwhile, in the present embodiment, a method of storing a still image in the photographing terminal 100 is described, but it is also possible to store the still image in the control terminal 200 instead of the photographing terminal 100. In this case, when a still image storage command is input from the user to the control terminal 200, the control unit 290 of the control terminal 200 extracts the current frame of the preview image received from the photographing terminal 100 and stores the storage unit ( 250). In addition, various applications are possible, such as storing them in both terminals 100 and 200.

When the storage of the still image is completed in step S34, the shooting terminal 100 transmits a still image storage completion signal to the control terminal 200 in step S35.

Accordingly, the control terminal 200 displays a message indicating that the storage of the still image is completed through the display unit 250. Therefore, the user may recognize that the still image is completed without error through the displayed message.

The process of capturing and storing the video remotely through the above process is performed through the process S25 to S36, and when these processes are repeatedly performed, a plurality of still images are stored in the storage unit 150.

On the other hand, if the user wants to end the recording, in step S37 the user requests to cancel the image shooting control through the key input unit 260 of the control terminal 200. Accordingly, the control terminal 200 transmits an image capturing control release request signal to the capturing terminal 100. Meanwhile, in the present embodiment, an example of requesting the release of the image capturing control through the control terminal 200 has been described, but it is also possible to release the image capturing control using the capturing terminal 100.

Next, the photographing terminal 100 receiving the image capturing control release request signal in step S37 transmits an image capturing control release approval signal in step S38. At the same time, the transmission of the preview image which was being transmitted to the control terminal 200 in step S39 is stopped, and the driving of the camera unit 130 is stopped in step S40.

Meanwhile, the control terminal 200 receiving the image control release approval signal stops displaying the preview image in step S41.

Next, an embodiment of video recording according to the remote photographing method of the present invention will be described.

5 is a flowchart schematically illustrating a video photographing process according to a remote photographing method of the present invention, and FIG. 6 is a flowchart schematically illustrating a video photographing process of a mobile communication terminal for photographing according to the present invention. 7 is a diagram illustrating an image storage request setting screen according to the present embodiment, and FIG. 8 is a flowchart schematically illustrating a video generation and storage process of FIG. 6 according to the present invention.

The video photographing process according to the present embodiment is similar to the above-described embodiment, and has a difference in the processes below the video storage request (S59 to S71 in FIG. 5). That is, the process S50 to S58 of the present embodiment is performed in the same manner as the process S20 to S28 of FIG. 3 according to the above-described embodiment, and only shows differences thereafter. Therefore, a detailed description of the same process will be omitted and will be described based on the following process (S59 to S71 process of FIG. 5) below the video storage request.

1, 2B, and 5 through 8, in a state in which the preview image is transmitted to the control terminal 200 through S50 to S58, the user requests a video storage request to the control terminal 200. When input, the control terminal 200 displays the image capture request screen shown in FIG.

In the image capturing request screen, a portion P on which a preview image is displayed and a key B for requesting storage of a moving image or a still image are located below. The lower end portion R is provided for setting sound recording. In the present embodiment, the user selects the sound recording setting through the video shooting request screen, and then requests a video storage. The sound recording setting will be described in detail as follows.

In the case of capturing and storing a moving image, a method of receiving image data and sound data, respectively, and generating and storing moving image data (hereinafter, a moving image) by combining the input image data and sound data is used. In the related art, images and sound data are generated by receiving an image and sound using one terminal (eg, a photographing terminal).

However, the present invention utilizes the photographing terminal 100 and the control terminal 200 simultaneously, and controls the photographing terminal 100 remotely by using the control terminal 200 to photograph an image. That is, the user uses a method of positioning the photographing terminal 100 in a suitable place so that the image is photographed in a desired composition, moving to a desired position, and checking the photographing method through the control terminal 200 to be displayed on the preview image.

As described above, since the remote photographing method uses the photographing terminal 100 and the control terminal 200 together, both sides of the audio processor 140 of the photographing terminal 100 and the audio processor 240 of the control terminal 200 are used. Both can generate sound data.

Here, sound recording is divided into normal recording and separate recording. In the case of general recording, it refers to a method of generating sound data by receiving sound through the audio processor 140 of the photographing terminal 100. In the case of separate recording, it refers to a method of generating sound data by receiving sound through the audio processor 240 of the control terminal 200.

Therefore, when the sound source to be combined with the image data is close to the photographing terminal 100, the user can set the sound recording to the normal recording. Similarly, when the sound source is in close proximity to the control terminal 200, the user can set the sound recording as a separate recording.

When the user completes the sound recording setting through the video shooting setting screen and completes the video recording request, the remote recording unit 292 of the control terminal 200 transmits a video storage request signal to the recording terminal 100 in step S59. . At this time, the sound recording setting information set by the user, that is, data indicating whether the normal recording or the separate recording is also transmitted.

The terminal 100 for receiving the video recording request signal and the sound recording setting information transmits the video storage response signal to the control terminal 200 in step S60. Subsequently, the photographing terminal 100 generates a video in step S600.

The image generating unit 196 of the photographing terminal 100 first checks whether the transmitted sound recording setting information is separate recording or general recording.

In the case of normal recording, the process proceeds to step S61, and the image generating unit 196 of the photographing terminal 100 receives sound through the audio processing unit 140 of the photographing terminal 100 and continuously generates sound data, which is an image. Combine with the data to create a video.

Meanwhile, in the case of separate recording, the image generating unit 196 of the photographing terminal 100 transmits a sound data request signal to the control terminal 200 in step S601.

The control terminal 200 receives the received sound through the audio processor 240 of the control terminal 200 in step S602 to continuously generate sound data. Then, the generated sound data is transmitted to the photographing terminal 100.

The image generating unit 196 of the photographing terminal 100 receiving the audio data in step S603 is transmitted from the control terminal 200 and the image data generated through the camera unit 130 of the photographing terminal 100 in step S61. Combined sound data is created and saved. At this time, since the image data and the sound data are continuously generated and input in real time, the video is also continuously generated and stored in frame units. In addition, the image data is continuously transmitted to the control terminal 200 in the process of storing the video as described above.

Meanwhile, the remote photographing unit 292 of the control terminal 200 receiving the video storage response signal in step S60 displays the phrase 'recording' or an icon (not shown) at an arbitrary position on the screen in step S62. Flashes and displays. This makes it easy for a user to recognize that a video is currently being stored.

Then, when the user requests to stop storing the video through the key input unit 260 of the control terminal 200 in order to stop the storage of the video, the control terminal 200 sends a request to stop the storage to the photographing terminal 100 in step S63. send. In step S64, the photographing terminal 100 receives the transmission and stops (or completes) the video storage. In this process, as in the above-described still image storing process, the controller may automatically assign a file name of the moving image to be stored, or receive and input it to the user.

Here, in the present embodiment, a process of storing a video in the storage unit 170 of the photographing terminal 100 is described, but it is also possible to store the video in the storage unit 270 of the control terminal 200. Although not shown, a brief description of the process of storing the video in the control terminal 200 is as follows.

When the user sets the sound recording to the normal recording and requests the video to be stored, the photographing terminal 100 transmits the sound data generated through the audio processor 140 of the photographing terminal 100 together with the image data. The remote photographing unit 292 receives sound data and image data from the photographing terminal 100, combines them, and generates and stores a video.

On the other hand, if the user sets the audio recording to separate recording and then requests video recording, the photographing terminal 100 transmits only image data, and the remote photographing unit 292 of the control terminal 200 of the control terminal 200 After receiving the sound data generated through the audio processor 240, the video data is generated and stored in combination with the image data.

In addition, a variety of applications are possible, such as storing videos together on both terminals simultaneously.

When the storage of the video is completed in step S64, the shooting terminal 100 transmits a video storage completion signal to the control terminal 200 in step S65.
