1 is a diagram schematically showing the configuration of an entire system for providing a surveillance image according to an embodiment of the present invention.

Referring to FIG. 1, a system for providing a monitoring image of a remote site to a mobile communication terminal user according to the present invention includes a mobile communication terminal 100, a wireless communication network 110, a base station 120, a communication network 130, and remote monitoring. Server 140 and remote monitoring camera 150 may be included.

The mobile communication terminal 100 receives and outputs a surveillance image captured by the remote monitoring camera 150 from the remote monitoring server 140 connected through the wireless communication network 110 and the communication network 130.

According to an exemplary embodiment of the present invention, the mobile communication terminal 100 may receive a surveillance image when communicating with the base station 120 in the standby state.

In this case, the idle state refers to a state in which the mobile communication terminal 100 receives a pilot signal from a base station and maintains synchronization.

When the user turns on the mobile communication terminal 100, the mobile communication terminal 100 enters an initialization state. In this case, the mobile communication terminal 100 selects a system of a mobile communication company in which the mobile communication terminal 100 is registered using information stored in the mobile communication terminal 100, and performs short PN code and long PN code timing using a pilot channel and a synchronization channel. Do a synchronous task of matching. The state after this process is called a standby state, and in some cases, the standby state may be used as a meaning including a state in which the mobile communication terminal 100 monitors a call (paging) channel. And a state in which a dedicated channel for receiving surveillance video is not set in addition to a state in which a base station and a common channel are connected, such as a call channel.

A method of receiving the surveillance image in the standby state by the mobile communication terminal 100 according to the present invention will be described in detail with reference to FIG. 2.

The mobile communication terminal 100 according to the present invention can be applied without limitation as long as the terminal is provided with communication means and can transmit and receive video / audio data. That is, a cellular phone, a PCS phone, a PDA phone and the like are typical examples, but the present invention is not limited thereto. Components of the mobile communication terminal 100 according to the present invention will be described in detail with reference to FIG. 8.

The wireless communication network 110 may be applied without limitation as long as the wireless communication network 110 may provide a wireless data service to the mobile communication terminal 100 by employing a code division multiple access (CDMA), a time division multiple access (TDMA), an IMT2000 scheme, or the like. .

The base station 120 performs a function of connecting the mobile communication terminal 100 and the remote monitoring server 140. That is, it relays a control message transmitted / received between the communication terminal 100 and the remote monitoring server 140, and transmits the surveillance image received from the remote monitoring server 140 to the mobile communication terminal 100. It performs the function.

The communication network 130 connects the base station 120, the remote monitoring server 140, and the remote monitoring camera 150, and serves as a moving path for transmitting a surveillance image captured from a remote location to the mobile communication terminal 100. In addition, although not shown in FIG. 1, the communication network 130 may be a wired or wireless communication network for each section. Description thereof is somewhat distance from the gist of the present invention, and thus detailed description thereof will be omitted.

The remote monitoring server 140 receives the surveillance video captured by the remote monitoring camera 150, edits the request according to the request of the mobile communication terminal 100, and transmits the edited surveillance image to the mobile communication terminal 100. Can be performed. That is, the remote monitoring server 140 lowers the frame rate of the surveillance video to an appropriate size (for example, 20 frames per minute) when the surveillance video desired by the mobile communication terminal 100 is a still image slide. 100 can be sent.

The remote surveillance camera 150 may be a security surveillance camera (eg, a network camera, a web camera, etc.) installed at a distance from a user of the mobile communication terminal 100. In addition, one or more remote monitoring cameras 150 may be provided, and in the case where a plurality of remote monitoring cameras 150 are provided, when the mobile communication terminal 100 receives a surveillance image, the surveillance image may be sequentially or randomly received through the identifier. You can tell which camera the video is from.

2 is a flowchart illustrating a method of receiving a surveillance image in a standby state by a mobile communication terminal according to an exemplary embodiment of the present invention, and FIG. 3 is a standby state option window of a remote monitoring application according to an exemplary embodiment of the present invention. It is a diagram showing.

Referring to FIG. 2, in step 210, the user remotely monitors the mobile communication terminal 100 in order to receive a surveillance image collected from a remote monitoring camera 150 installed at a remote place in a standby state of the mobile communication terminal 100. Run the application.

In this case, the installed application may provide the standby state option window 300 as shown in FIG. 3. The standby state option window 300 may include a camera selection (when there are a plurality of cameras), a resolution, a frame rate, a data format, and a data storage capacity selection menu. 3 is only an embodiment according to the present invention, but the present invention is not limited thereto.

Referring to FIG. 3, the camera selection menu may be inactivated so as not to select a menu when the remote monitoring camera 150 is one, or may be included only in a plurality of cases. In addition, when there are a plurality of remote surveillance cameras 150, the surveillance images collected by each remote surveillance camera 150 are individually edited according to selection of an option in the remote surveillance server 140 and transmitted to the mobile communication terminal 100. Can be. For example, when two remote surveillance cameras 150 are installed and two surveillance images are received by the mobile communication terminal 100, the frame rate of the first surveillance image is 60 frames per minute and the frame rate of the second surveillance image is 1. It can be 240 frames per minute.

The resolution selection menu is a menu for selecting an RGB format size of a received surveillance image. Resolution matters will be apparent to those skilled in the art, and thus detailed descriptions thereof will be omitted.

The frame rate is the number of transmitted per second or per minute. For example, when transmitting a television signal or the like, only a suitable number of screens () are transmitted per second by using human visual characteristics. to be. However, since the present invention receives data through the wireless communication network 110 and the surveillance image is received in the standby state of the mobile communication terminal 100, it is preferable that the frame rate is not excessively high.

The data format is a menu for selecting the data format of the surveillance video received by the mobile communication terminal 100. For example, the surveillance video may be in avi format, but the present invention is not limited thereto.

The data storage capacity is a menu for setting the maximum value of data corresponding to the surveillance video stored in consideration of the data storage capacity of the mobile communication terminal 100. For example, when the data storage capacity is set to 100 Mbyte, the surveillance video stored in the standby state of the mobile communication terminal 100 may not exceed 100 Mbyte, and when the data storage capacity exceeds 100 Mbyte, the stored data may be deleted in a first-in first-out (FIFO) method. Can be. That is, the oldest data can be deleted from the oldest data. Of course, when there are a plurality of remote surveillance cameras 150, data storage capacity may be set individually for the surveillance images captured by each of the remote surveillance cameras 150. FIG.

If the user enters the mobile communication terminal 100 in the standby state in step 220, the mobile communication terminal 100 proceeds to the subsequent step according to the operation of the remote monitoring application driven in step 210. In this case, the standby state of the mobile communication terminal 100 refers to a call waiting state as described above. In other words, when the mobile communication terminal 100 is a slide type mobile phone, the mobile communication terminal 100 may be in a state of sliding down after driving a remote monitoring application in a slide-up state. However, the remote monitoring application should perform an operation so that the surveillance video can be received through the forward channel even when the slide is down.

In step 230, the mobile communication terminal 100 entering the standby state communicates with the base station 120 to obtain a pilot channel as in a normal operation. Here, the forward pilot channel provides a time and phase reference to the mobile communication terminal 100 and provides reference (PN offset) information for identifying the base station 120.

In step 240, the mobile communication terminal 100 communicates with the base station 120 to obtain a synchronization channel. Here, the forward synchronization channel provides the mobile communication terminal 100 with information necessary for initial synchronization of the base station, and the mobile communication terminal 100 no longer watches the synchronization channel once the initial synchronization information is obtained through the synchronization channel. Transfer to the call channel reception state.

Of course, the mobile communication terminal 100 should periodically monitor the pilot channel in preparation for the occurrence of handover as the user moves. Although not shown in FIG. 2, if a handover occurs according to the movement of the location of the user of the mobile communication terminal 100, steps 210 and 220 should be performed again.

In operation 250, the remote monitoring server 140 receives a surveillance image from the remote monitoring camera 150 connected with the communication network 130. In this case, when there are a plurality of remote surveillance cameras 150, the remote surveillance server 140 may receive a surveillance image including an identifier to prevent the surveillance image from being mixed. In addition, the remote monitoring server 140 is the mobile communication terminal 100 is received from the plurality of remote monitoring camera 150 when the surveillance video received from the plurality of remote monitoring camera 150 is received through a separate port. An identifier may be included in the surveillance video so that the surveillance video can be distinguished.

In operation 260, the remote monitoring server 140 edits the received surveillance image according to the standby state option setting of the remote monitoring application driven in operation 210. In this case, the surveillance video may convert one or more of resolution, frame rate, and data format. Of course, step 260 may be omitted if there is no option setting.

The surveillance video edited in step 270 is included in an empty frame of data received through a forward channel (for example, a pilot channel, a synchronization channel, a call channel, and the like) of the mobile communication terminal 100 to the mobile communication terminal 100. Can be sent. In this case, since the surveillance video is transmitted in the standby state of the mobile communication terminal 100, it may be preferable to transmit the surveillance video using an empty frame of the existing forward channel without securing a dedicated channel for transmitting the surveillance video. Here, the general call channel is composed of information related to the overall system configuration and information such as a response to a terminal call and a terminal request.

4 is a flowchart illustrating a method of providing a surveillance video stored in a standby state of a mobile communication terminal according to an exemplary embodiment of the present invention.

In step 410, the user of the mobile communication terminal 100 drives the remote monitoring application to set the standby state option and then enters the mobile communication terminal 100 into the standby state. Detailed description thereof will be omitted below.

In operation 420, the mobile communication terminal 100 receives and stores the surveillance image from the remote monitoring server 140. The surveillance image is omitted since the detailed description on the reception has been made above.

In step 430, the mobile communication terminal 100 determines whether the stored surveillance image exceeds the set data amount according to the standby state option setting shown in FIG. If the stored surveillance image exceeds the set amount of data, the mobile communication terminal 100 may proceed to step 440 to delete the stored data in a first-in first-out manner. However, the data deletion method according to the present invention is not limited thereto. If the surveillance video stored in step 430 does not exceed the set data amount, step 450 is performed. In addition, although not shown in FIG. 4, when the received surveillance image is an image received from the plurality of remote surveillance cameras 150, whether or not data is exceeded may be determined for each surveillance image according to the standby state option setting. Of course, if the data storage capacity option shown in FIG. 3 is not selected, step 430 may be omitted, or it may be determined whether to delete data according to a default value.

In operation 450, the mobile communication terminal 100 determines whether an activation command of the mobile communication terminal 100 is received from the user. If the activation command of the mobile communication terminal 100 is not received from the user, the mobile communication terminal 100 proceeds to step 420 to receive and store the surveillance image. If the activation command of the mobile communication terminal 100 is received, step 460 is performed. Here, the activation command may be an output command of a pre-stored surveillance image as a standby state release command of the mobile communication terminal 100. In addition, the activation command may be a command for setting a dedicated data transmission / reception channel between the mobile communication terminal 100 and the remote monitoring server 140 for receiving and outputting a real-time monitoring image.

In addition, the activation command of the mobile communication terminal 100 may be received through input of a user's preset key (for example, a popup service activation button set in the mobile phone). In addition, when the mobile communication terminal 100 is a slide type mobile phone, when the slide is in the up state, the mobile communication terminal 100 may recognize that an activation command is input.

In operation 460, the mobile communication terminal may edit the pre-stored surveillance image into a preset image format and proceed to operation 470 to output the mobile communication terminal 100 for viewing. For example, the mobile communication terminal 100 may convert a frame rate of a previously stored surveillance image and play the surveillance image as a still image or a video having a frame rate converted therein. That is, when the frame rate of the stored surveillance image is 360 frames per minute, it can be converted to 20 frames per minute and output in the still image slide format. Of course, the format of the stored surveillance video may be output as it is without conversion. In this case, the output surveillance video may be recognized as a video.

The surveillance video output according to the input method of the activation command may be an image in which a preset data format is converted or an image not converted. For example, a surveillance image output according to a preset key button (for example, a still image output button) is output according to an image (eg, still image or still image slide) or slide up of which data format is converted. The output surveillance image may be an image in which a data format is not converted.

5 is a flowchart illustrating a method of providing a surveillance image when a motion occurs in a standby state of a mobile communication terminal according to another exemplary embodiment of the present invention.

Referring to FIG. 5, in operation 510, the mobile communication terminal 100 may receive a surveillance image captured by the remote monitoring camera 150 from the remote monitoring server 140. Here, since the mobile communication terminal 100 receives the surveillance image as described above, a detailed description thereof will be omitted. In addition, the mobile communication terminal 100 may store the received surveillance image (not shown). Here, when storing the surveillance image, the mobile communication terminal 100 may further perform a process of determining whether the stored surveillance image exceeds a preset data amount and a data deletion process according to the standby state setting option (FIG. 4). Reference). Since a detailed description thereof has been made above, it will be omitted. In addition, since the remote monitoring application driving process shown in FIG. 4 was also described above, it will be omitted and will be described with reference to the difference between FIG. 4 and FIG. 5.

In operation 520, the mobile communication terminal 100 may determine whether a motion occurs by comparing the received surveillance image. For example, when a remote surveillance camera is installed in a house and the user of the mobile communication terminal 100 is out, the mobile communication terminal 100 compares the received surveillance image to determine whether there is an invasion of an outsider in the house. can do. Here, the process of determining whether the mobile communication terminal 100 has a motion will be described in detail with reference to FIG. 6.

If no movement occurs in step 520, the mobile communication terminal 100 proceeds to step 510 and repeats a process of receiving a surveillance image. If the mobile communication terminal 100 has a motion in the surveillance image, the mobile communication terminal 100 may output a warning signal so that the user of the mobile communication terminal 100 may recognize the motion in step 530. Here, the warning signal may be applied without limitation as long as it is a message type that can be recognized by the user (for example, a voice signal or a light emitting lamp lighting signal).

In operation 540, the mobile communication terminal 100 may edit the surveillance image according to a preset data format and then proceed to operation 550 to output the surveillance image. Here, the output surveillance image may be a still image at the time when the movement occurs, or may be a video corresponding to a preset time.

6 is a flowchart illustrating a method of determining whether a motion occurs by analyzing a surveillance image according to an exemplary embodiment of the present invention.

Referring to FIG. 6, the mobile communication terminal 100 may receive a surveillance image from the remote monitoring server 140. As described above, the surveillance image may be data included in an empty frame of the forward channel in the standby state of the mobile communication terminal 100. Here, the process of separating the data included in the empty frame of the forward channel by the mobile communication terminal 100 is a little distance from the gist of the present invention will be omitted.

In step 620, the mobile communication terminal 100 compares frames corresponding to two or more consecutive surveillance images, and then proceeds to step 630 to determine whether a change has occurred over a preset value in the consecutive frames. If there is no change in the frame corresponding to the surveillance image by more than a preset value, the mobile communication terminal 100 proceeds to step 610 to receive the surveillance image from the remote monitoring server 140.

If a change in the frame corresponding to the surveillance image is greater than or equal to a preset value, the mobile communication terminal 100 may proceed to step 640 to determine that the movement has occurred in a place where the remote surveillance camera 150 is installed. In other words, if the frame corresponding to the surveillance image does not change in motion, its data value cannot be changed suddenly, so that the mobile communication terminal 100 has invaded the place where the remote surveillance camera 100 is installed when the data value suddenly changes. You can judge.

In addition, according to another exemplary embodiment of the present invention, the mobile communication terminal 100 may determine whether motion has occurred by comparing frames corresponding to surveillance images having a preset time interval. In this case, the mobile communication terminal 100 may save battery resources that must be consumed for detecting the occurrence of motion.

The mobile communication terminal 100 recognizing the occurrence of the movement may proceed to step 650 and may activate itself according to a setting of a preset remote monitoring application to output a still image at the time when the movement occurs. Alternatively, the mobile communication terminal 100 may output a video from the time when the movement occurs.

In addition, in FIG. 6, the mobile communication terminal 100 determines whether the movement occurs. According to another embodiment of the present invention, the remote monitoring server 140 and the remote monitoring camera 150 connected to the mobile communication terminal 100 also move. It can be determined whether or not it occurred. In addition, the remote monitoring server 140 may be provided with a separate device for determining whether the motion occurs. In this case, the method for determining whether the remote monitoring server 140 and the remote monitoring camera 150 generate a motion in the surveillance image may be applied to the method for detecting the movement of the mobile communication terminal 100 described above. . In addition, the remote monitoring camera 150 may include a sensor for detecting a movement or a sound to determine whether the movement occurs.

When a device other than the mobile communication terminal 100 recognizes a movement, a notification message (for example, SMS, MMS, etc.) is transmitted to the mobile communication terminal 100 so that the mobile communication terminal 100 can recognize the movement occurrence. Could be.

7 is a flowchart illustrating a method of providing a surveillance image in an activated state of a mobile communication terminal according to an exemplary embodiment of the present invention.

As described above, when the mobile communication terminal 100 receives an activation command from the user of the mobile communication terminal 100, the mobile communication terminal 100 may enter the activated state from the standby state. In addition, when a movement occurs in the surveillance image received in the standby state, the mobile communication terminal 100 may enter an activated state.

Referring to FIG. 7, the mobile communication terminal 100 entering the activation state in step 710 is a path for transmitting / receiving dedicated data via the base station 120 to receive a surveillance image from the remote monitoring server 140. Set.

The mobile communication terminal 100 that has set a path for transmitting / receiving dedicated data may reset the data format of the surveillance video to be received from the remote monitoring server 140 (for example, a frame rate of the surveillance video to be received). have. For example, the mobile communication terminal 100 may change the frame rate of the surveillance video set in the standby state option to 360 frames per minute when the frame rate is 180 frames per minute. Here, the change of the frame rate may be preset through an activation state option (not shown) of the remote monitoring application. In this case, the frame rate change will be executed according to the operation of the remote monitoring application without a user's separate command. In addition, the mobile communication terminal 100 may be set according to a user's input after entering the activation state.

In addition, when there are a plurality of remote monitoring cameras 150, the mobile communication terminal 100 may request a surveillance image captured by a specific remote monitoring camera 150. In this case, the selection of the specific remote monitoring camera 150 may be selected according to a user's input. In addition, the remote monitoring camera 150 may be set according to the operation of a preset remote monitoring application, which captures a monitoring image in which motion is detected among the plurality of sensing images received in the standby state.

In operation 720, the remote monitoring server 140 transmits a real-time surveillance video request to the remote monitoring camera 150. In this case, when there are a plurality of remote monitoring cameras 150, the remote monitoring server 140 may transmit a real-time monitoring video request to a specific remote monitoring camera. In addition, the remote monitoring server 140 may request a surveillance image for all of the plurality of remote monitoring cameras 150.

In operation 730, the remote surveillance camera 150 that receives the real-time surveillance image request transmits the captured surveillance image to the remote surveillance server 140. In this case, when there are a plurality of remote surveillance cameras 150, the surveillance image may include an identifier of the remote surveillance camera 150 to distinguish individual surveillance images as described above.

In operation 740, the remote surveillance server 140 may edit the surveillance image based on a request of the mobile communication terminal 100 for the surveillance image received from the remote surveillance camera 150. For example, the frame rate, resolution, and the like of the surveillance video can be converted. Of course, if there is no request from the mobile communication terminal 100, step 740 may be omitted.

The surveillance video edited in step 750 is transmitted to the mobile communication terminal 100 via the base station 120. Here, the mobile communication terminal 100 may store the received surveillance image.

In operation 760, the mobile communication terminal 100 may stop the output of the surveillance video stored in the standby state in order to reproduce the real-time surveillance video.

In operation 770, the mobile communication terminal 100 may edit the received surveillance image in a preset data format or edit a surveillance image by receiving a user's command. That is, step 770 may be performed when the format for storing the surveillance image received in step 750 is different from the format for outputting in real time. However, if the user wants to output only the real time without format conversion of the received surveillance image, step 770 may be omitted.

In operation 780, the mobile communication terminal 100 outputs the edited surveillance image for viewing by the user.
