FIG. 4 is a flowchart illustrating an image capturing control method in an apparatus for controlling image capturing according to the present invention, and illustrates a method of operation in a device which controls an image capturing function of a wireless communication terminal.

First, the control unit 21 of the image capturing control apparatus 20 releases the restriction signal for limiting the image capturing function of the wireless communication terminal entering the video capturing restricted area and the restriction of the image capturing function of the wireless communication terminal. The signal generator 22 is controlled to generate a signal (410).

Thereafter, the signal generator 22 of the image photographing control device 20 generates the limit signal and the release signal (420).

Thereafter, the limit signal output unit 23 and the release signal output unit 24 of the image capturing control apparatus 20 output the limit signal and the release signal at regular intervals (430).

At this time, the restriction signal is output from the restriction signal output unit 23 of the video recording control device 20, which is installed inside the video recording restricted area entrance, the release signal is installed outside the video recording restricted area entrance. The signal is output from the release signal output unit 24 of the image capturing control device 20.

According to the process of the camera unit is shown.

First, the wireless communication terminal receives a limit signal or a release signal output from the image capture control device 20 (510).

Here, the limit signal is a signal output from the limit signal output unit 23 of the image capturing control apparatus 20 located inside the image capturing restricted region, and stops the operation of the camera unit 39 to limit the image capturing. The release signal is a signal output from the release signal output unit 23 of the image capture control device 20 located outside the image capture restriction region, and is used to restore the operation of the camera unit 39. It is a signal.

In addition, since the restriction signal and the release signal is a signal of a frequency band for short-range wireless communication used by a general wireless communication terminal, the wireless transmission and reception unit 30 of the wireless communication terminal does not need a separate receiver for receiving the restriction signal. Receive is possible.

Thereafter, the control unit 34 of the wireless communication terminal determines whether the signal received from the image capture control device 20 is a limit signal or a release signal (520).

As a result of the determination 520, if the signal received from the image capturing control device 20 is a limit signal, the process proceeds to steps 531 to 536, and if the signal received from the image capturing control device 20 is a release signal, 541. Up to 546.

First, the case in which the signal received from the image capturing control device 20 is a limit signal will be described.

Accordingly, even if the user of the wireless communication terminal turns off the power of the wireless communication terminal and turns it on again, since the restriction signal is still stored in the restriction signal memory 351, the image photographing function of the camera unit 39 is limited.

Thereafter, as the key signal associated with the camera unit 39 is input through the input unit 36 of the wireless communication terminal 532, the controller 34 determines whether the limit signal is stored in the limit signal memory 35. Search (533).

Subsequently, if the search result 534 and the limit signal are stored, the control unit 34 deactivates the camera unit driving signal (535), and the back end unit 37 transmits the deactivated camera unit driving signal to the camera unit 39. In operation 536, a message indicating that the camera unit 39 cannot drive the camera 39 is being displayed, indicating that image capturing is impossible.

If the search result 534 and the limit signal are not stored in the limit signal memory 351, the control unit 34 activates the camera unit driving signal (544), and the back end unit 37 activates the activated camera. It transmits the sub-drive signal to the camera unit 39, and displays the driveable message of the camera unit 39 "Camera ready" to indicate that the image can be taken on the display unit 38 (545), The camera unit 39 operates according to the key signal associated with the camera unit 39 (546).

In this case, the driving impossible message of the camera unit 39 "stopping the camera function" and the camera driving possible message "camera preparing" are stored in the message storage unit 352 in the storage unit 35. The type is not limited to the contents of the above two messages, and it is clear that the user may arbitrarily create another message and store the message in the message storage unit 352 for use.

Next, the process of the case where the signal received from the image capture control device 20 is determined to be a release signal rather than a limit signal (520).

First, if the signal received by the wireless communication terminal is a release signal, the controller 34 receiving the signal searches whether the limit signal is stored in the limit signal memory 351 (541).

As a result of the search, if the restriction signal is not stored, the wireless communication terminal operates as a general wireless communication terminal, and if the search result restriction signal is stored, the controller deletes the restriction signal stored in the restriction signal memory 351 ( 542).

Subsequently, when a key signal associated with the camera unit 39 is input through the input unit 36 of the wireless communication terminal 532, the wireless communication terminal operates in steps 544 to 546, and the description thereof has been described above. do.

Therefore, when the wireless communication terminal enters the video recording restriction area, the camera sub-function is stopped by receiving the restriction signal output from the restriction signal output unit 23 of the video recording device 20, and the video recording function is stopped. When the wireless communication terminal that has been out of the video recording restriction area receives a release signal for releasing the video recording function restriction from the release signal output unit 24 in the video recording control device 20, the camera unit function is restored again. You will be able to shoot video normally.

The present invention described above is capable of various substitutions, modifications, and changes without departing from the technical spirit of the present invention for those skilled in the art to which the present invention pertains. It is not limited by the drawings.

The present invention as described above, when the wireless communication terminal is in the video recording restricted area has an effect that can automatically stop the camera function according to the restriction signal to prevent unauthorized shooting, and if you are out of the video recording restricted area In this case, the camera function can be automatically restored according to the release signal.
