FIG. 4 is a flowchart showing the processing operation of the portable terminal, and FIG. 5 is a flowchart showing the processing operation of the portable terminal of the remote image monitoring apparatus.

As shown in the flow charts of FIGS. 4 and 5, after the initial setting (S1, S21) of the portable terminal and the remote image monitoring device, the portable terminal waits for an operation from a supervisor and the remote image monitoring device. Waiting for incoming call from (S
2 to S13), the remote image monitoring apparatus inputs signals from various sensors and waits for an incoming call from the mobile terminal (S22 to S13).
The process proceeds to S34). In both cases, when a request corresponding to the standby operation is made during the standby operation, the corresponding operation is executed, and then the standby operation is repeated. When a power-off request is issued during the standby operation, the power is turned off and the process is terminated (S13, S14, S3).
4, S35).

Next, the standby operation of the portable terminal shown in FIG. 4 will be described in detail. As described above, the standby operation of the mobile terminal waits for an operation from a supervisor (S4, S6, S11, S1).
3) and waiting for a monitoring signal from the remote image monitoring device (S
2). The determination of the presence or absence of the notification shown in S2 is a sensor detection signal notification from the remote image monitoring device, and the mobile terminal that has received the notification notifies the monitoring personnel of the signal reception (S3). Upon receiving the notification, the monitor calls the remote image monitoring apparatus that sent the notification (S6 to S10), and the mobile terminal-specific I
When the D / password is transmitted to the remote image monitoring device and the connection is permitted (S8 to S10), an image is received from the monitoring camera corresponding to the sensor detected by the remote image monitoring device, and the status of the monitoring target is confirmed. It will be. Further, when the observer determines that operations such as door lock, lighting of lights, and buzzer sounding are required for the monitoring target location, these commands are transmitted to the remote image monitoring device using the numeric keypad of the mobile terminal ( S5).

Further, the standby operation of the remote image monitoring apparatus shown in FIG. 5 will be described in detail. The standby operation of the remote image monitoring apparatus is, as described above, an operation of waiting for a signal input from various sensors (S22) and an operation of waiting for an incoming call from a portable terminal (S27). When the remote image monitoring device detects signals from various sensors (S22), it records an image signal from the monitoring camera (S23) and makes a call to the mobile terminal (S24). If the line connection to the mobile terminal is successful, the monitoring image is transmitted (S26). If the line connection to the portable terminal fails, a retry operation is started (S36), and if the number of retry operations is within the specified retry frequency range, the calling (S24) is repeated. At this time,
Parameters such as the number of retries are recorded in the remote image device (S37). If the number of retries exceeds the specified value, give up the call. The parameter is notified to the mobile terminal at the same time as the transmission of the monitoring image when the next incoming call from the mobile terminal succeeds, as described below (S26). Next, an incoming call request from the portable terminal (S27) is conditionally handled (S28, S29). This is to protect the remote image monitoring device from an unauthorized connection request from a person other than the observer. In order to determine whether connection is possible, an ID and a password from the mobile terminal are registered in the remote image monitoring device in advance. If the connection is permitted, login is permitted. If not, the line is disconnected (S29, S38), and the process returns to the standby operation. If the login is permitted, an operation command (monitoring camera switching control, imaging direction control of the monitoring camera, focus control, signal output control to the other monitoring device) from the mobile terminal is accepted (S31). At the same time, the image of the surveillance camera is transmitted to the mobile terminal (S32, S33).

[0020]

As described above in detail, according to the present invention, the terminal operated by the observer is a portable telephone having an image display function, so that a fixed monitor like a conventional monitor is provided. The supervisor can be released from the terminal, and the status of the monitoring place can be quickly grasped even while moving. In addition, by directly sending the monitoring signal to the mobile phone that is expected to be constantly energized, when the image monitoring device detects a signal from the sensor, the monitoring signal can be easily notified to the monitor. Since the monitoring signal notified from the image monitoring device includes an image captured when a signal is input from the sensor, the monitoring staff can immediately determine the status of the monitoring target location. Material is provided. Also, by layering and recording the recorded images,
From one image file, an image with a corresponding resolution can be reproduced according to the image display capability of the terminal. For example,
In the case of a two-stage (high-frequency and low-frequency) layering, in the case of displaying an image on a mobile terminal, reproduction in only the low frequency region, that is, a screen display larger than a mobile terminal screen such as a so-called desktop computer screen is possible. For this, image reproduction in the entire band (both in the low band and the high band) becomes possible.
