DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a video and audio transmission / reception system combining a digital photo function and an information communication function.

[0002]

2. Description of the Related Art Generally, a digital camera is known as a device having a digital photo function, and a simplified portable telephone system terminal called PHS (registered trademark) is also known as a portable information communication terminal. However, the two have no contact at all and have been used separately in their own fields.

[0003]

2. Description of the Related Art A digital camera is used as a communication means and a tool for a photographer to transmit information called a video to another person. Recently, this use is one of transmission of digitized information. It is starting to attract attention as a means. On the other hand, PHS is understood to have an effective role as a communication terminal, and has a transmission output of 10 mW and a mobile phone (6).
Despite being lower than 00 to 800 mW), the low cost advantage associated with the maintenance of the base station has resulted in the acquisition of a large number of users in a short period of time, but only the communication function is intended for use. In other words, both have developed independently as terminals, and until now the proposal of a system that utilizes both functions synergistically, and also utilizes it as a communication means, has been thoroughly studied as far as the inventor knows. That was not.

SUMMARY OF THE INVENTION The present invention relates to connecting a digital camera and a PHS, which have developed differently in the past, and constructing a video and audio transmission / reception system as a completely new communication means.

More specifically, the invention relating to a video and audio transmission / reception system according to claim 1 combines a digital camera and an audio terminal of a simplified portable telephone system integrally,
Prepare a portable digital transceiver that has a digital photo function and an information communication function, and directly accept and connect this digital transceiver, and can capture and print out the images in the digital transceiver. A printer is separately prepared so that both can be freely connected.

Accordingly, bidirectional transmission and reception of video and audio between digital transceivers, transmission of messages to facsimile machines, and selection of one of the plurality of digital printers provided in various places in advance and carrying them there. The printout of the video image by inserting the digital transceiver is performed at any time.

According to a second aspect of the present invention, there is provided an image and audio transmission / reception system, wherein a digital printer is formed so as to be capable of imprinting an image itself, and synthesizes with an image captured from a digital transceiver. It is something that can be done.

[0008]

DESCRIPTION OF THE PREFERRED EMBODIMENTS This video and audio transmission / reception system comprises at least a portable digital transceiver and a digital printer to form an overall system. As the digital transceiver, it is assumed that a digital camera and a voice terminal of a simplified portable telephone system are integrally combined. Since this is a kind of multi-function terminal, it is of course possible to provide both the digital photo function of the digital camera and the information communication function of the PHS. The voice terminal enables transmission and reception, while the audio terminal enables transmission or reception of the image data to another similar digital transceiver, and further enables transmission of the image data to another facsimile machine.

[0009] It is assumed that the digital printer can directly receive and connect the above-mentioned digital transceiver, and can capture and print out the image in the digital transceiver. The digital printer not only captures and receives the video from the digital transceiver described above, but can also capture the video itself so that the digital printer can synthesize the captured video from the digital transceiver.

[0010]

DESCRIPTION OF THE PREFERRED EMBODIMENTS Embodiments of the present invention will be described below with reference to embodiments. The digital transceiver 1 shown in FIG. 1 includes a digital camera unit 2 and a voice terminal (P
HS) unit 3 is integrally combined. The digital camera unit 2 is a 1/3 CCD solid-state imaging device (640 ×
480), a flash memory 4 MB, and a serial port for transmitting image data, adopting a square grid, all pixel reading method, and total pixel (350,000 pixel) reading method, and having an automatic date and time function. is there.

The voice terminal unit 3 has the original function of the PHS as it is, and transmits the image data of the digital camera unit 2 to another similar digital transceiver 1a, or conversely, receives the image data from the other similar digital transceiver 1b. Not only can it receive data, it can also send image data from the digital camera unit 2 to the facsimile machine 4, send an image to the telephone 5 via an answering machine service, and even send an image to the personal computer 6. It is like that. A text message can be combined with such an image.

As shown in FIG. 2, the digital printer 7 is a desktop-type sublimation type thermal printer, and has a touch panel 8 so that a screen can be input freely. The serial port dock 9 is provided with an insertion hole 10 for accepting the digital transceivers 1, 1a, 1b, etc., forming a connection state, and capable of directly receiving and receiving image data. It is possible to print out the combined image and the image captured from the digital transceivers 1, 1a, 1b by enabling the copying. The printout can be performed on plain paper by selecting the paper size, or the printout of the sticker print 11 such as a 16-screen sticker can be performed. In addition, a library with or without a frame is provided in advance,
It can be selected and printed out. Therefore 2
The use of a layered printer is preferred.

The transmission / reception state of digital data will be described with reference to FIG. 3. Reference numeral 20 denotes a cell, and each cell 20 includes a radio base station 21;
The digital signals from 1a and 1b are transmitted to the NTT (registered trademark)
The data can be transmitted to the facsimile machine 4, the telephone 5, the personal computer 6, or the like as each terminal through the toll switch 26 and the local switch 27 in the public network 25. If the digital transceivers 1, 1 a, and 1 b are located close to each other in the cells 20, it is a matter of course that both can transmit and receive image data.

If there is a digital printer 7 previously arranged in each cell 20, the digital transceiver 1, 1a or 1b carried there is directly sent to the serial port dock 9.
The image data can be received directly by inserting the image data into the insertion hole 10 and the printout condition can be selected. You can also enjoy it with a sticker print. Therefore, it is preferable that a large number of digital printers 7 are installed in a family restaurant, a convenience store, or any other location.

[0015]

As explained above, according to the present invention,
A portable digital transceiver having both a digital photo function and an information communication function, and a digital printer capable of directly receiving the digital transceiver and printing out the image in the digital transceiver,
At least, we will prepare a video and audio transmission / reception system, so that you can enjoy conversation while watching the video, and also synergistic information transmission between the image and the communication to improve the effect of the information communication. It is possible to further improve. In addition, since images can be combined, if sticker printout is performed by combining transmitted / received digital images and captured images, fun as communication means can be remarkably advanced.
