Abstract

Real-time images and audio are monitored anytime from an arbitrary remote place with a portable telephone. The portable telephone comprises a display panel, an image signal receiving part which receives an image signal sent over a mobile communication network, an image signal reproducing part which reproduces the received image signal and displays the reproduced image, and a permission signal sending part for sending a permission signal to permit an image-pickup part connected via the mobile communication network to output an image signal. According to another aspect, a portable telephone comprises a sending/receiving part which sends/receives an image signal via the mobile communication network, a display panel, and a CCD camera which performs imaging and sends an image signal by the sending/receiving part. The view of the surrounding area is sent to another portable telephone that via the mobile communication network.

Claims

1. A portable telephone comprising:

a display part which can display a moving image;

an image signal receiving part which receives an image signal sent over a mobile communication network;

an image signal reproducing part which reproduces said image signal which has been received by said image signal receiving part and makes said display part display a reproduced image; and

a permission signal sending part for sending a permission signal to permit an image-pickup part to output image signal to said image-pickup part to be connected via the mobile communication network.

2. A portable telephone as set forth in claim 1 further comprises a decompressing part for decompressing a compressed digital image signal which has been received by said image signal receiving part.

3. A remote monitoring system by means of a portable telephone, comprising:

a portable telephone; and

a monitoring camera device which is connected to said portable telephone via a mobile communication network and sends an image signal obtained by imaging, wherein

said portable telephone comprises;

a display part which can display a moving image;

an image signal receiving part which receives an image signal sent over the mobile communication network;

an image signal reproducing part which reproduces said image signal which has been received by said image signal receiving part and makes the display part display a reproduced image; and

a permission signal sending part for sending a permission signal to permit a monitoring camera device to output an image signal to said monitoring camera device to be connected via the mobile communication network, and wherein

said monitoring camera device comprises;

an image pickup part which is installed and oriented toward a desirable object to be monitored and an image signal sending permission part which detects the permission signal to be sent from the permission signal sending part of the portable telephone via the mobile communication network and permits sending of an image signal from said image-pickup part to said portable telephone.

4. A remote monitoring system by means of a portable telephone as set forth in claim 3, wherein said monitoring camera device further comprises a compressing part for compressing an image signal to be sent from said image pickup part to said portable telephone.

5. A remote monitoring system by means of a portable telephone as set forth in claim 3, wherein said portable telephone further comprises a decompressing part for decompressing a compressed image signal which has been received by said image signal receiving part.

6. A portable information terminal comprises:

a sending/receiving part which sends/receives an image signal via a mobile communication network;

an image display part which displays an image by said image signal received by said sending/receiving part; and

an image-pickup part which performs imaging and sends an image signal obtained through imaging by means of said sending/receiving part.

7. A portable information terminal as set forth in claim 6, wherein said image-pickup part is a CCD camera.

8. A method for using a portable information terminal which comprises a sending/receiving part which performs sending/receiving of an image signal via a mobile communication network, an image display part which displays an image in a form of an image signal received by said sending/receiving part, and an image-pickup part which performs imaging and sends image signals obtained through imaging by means of said sending/receiving part, said method comprising the steps of:

imaging a view of a surrounding area by means of said image-pickup device;

sending the image signal obtained through said imaging step to another portable information terminal that is line-connected via a mobile communication network by means of said sending/receiving part; and

making the image of the view of the surrounding area thus imaged to be displayed in an image display part of another portable information terminal.

9. A method for using a portable information terminal as set forth in claim 8, wherein

said view of a surrounding area to be imaged by said image-pickup device is a view of a surrounding area of a place of meeting.
