Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a portable radio telephone device, and more particularly to a portable radio telephone device capable of transmitting video information in addition to audio information.

[Conventional technology]

With the progress of the information society, pagers and portable radio telephones (cellular one-way radio telephones) have become widespread.

FIG. 5 is a perspective view showing such a conventional portable radio telephone device, in which a portable radio telephone body 1 includes a liquid crystal display 2. Speaker 3. Microphone 4. It is equipped with an antenna 5, a key button 6, a built-in circuit system (not shown), etc., and as is well known, it is possible to make and receive calls without a cord. or pre-memorized characters, such as a person's name, would be displayed.

However, although conventional nuclide portable radio telephone devices have the function of transmitting voice information and data information, they do not have the function of capturing and transmitting video information, or the function of transmitting the transmitted video signal. There was no function to import data and display it as an image.

[Problem to be solved by the invention]

As mentioned above, conventional portable wireless telephone devices are capable of receiving and receiving information that is difficult to convey sufficiently through voice alone, such as information on the appearance of objects, the images of both parties (personal identification), and scenery. I couldn't do it.

For example, in an emergency such as when an accident occurs, it is necessary to accurately inform the police station, fire department, etc. of the situation as soon as possible, but it is not possible to convey information accurately and quickly with voice information alone. The present invention was made in view of the above points, and its purpose is to provide a mobile phone capable of photographing and transmitting video information, or receiving and displaying video information. An object of the present invention is to provide a wireless telephone device for use in a mobile phone.

[Means to solve the problem]

The above-mentioned object of the present invention is to add and combine at least an image display means or at least an imaging means to a portable radiotelephone device, and the imaging means may be detachable from the main body of the portable radiotelephone as the case may be. This can be achieved by making it possible to display a captured video signal as a video, or by making it possible to transmit a captured image as a video signal.

[Effect]

The video signal received by the antenna of the portable wireless telephone device is appropriately processed by the processing circuit system and displayed as a video on a video display means, for example, a liquid crystal display, so that the caller can obtain video information along with audio information. I can do it. Further, various types of video information are captured by the imaging means and taken in as electrical signals, processed appropriately by the processing circuit system, and the video signals are transmitted from the antenna in the form of radio waves. This allows mutual video transmission by portable radio telephone devices.

〔Example〕

Hereinafter, the present invention will be explained with reference to illustrated embodiments.

1 and 2 relate to a portable radio telephone device according to an embodiment of the present invention, FIG. 1 being a perspective view thereof, and FIG. 2 being a block diagram thereof.

In the figure, reference numeral 1 denotes a portable radio telephone main body, which roughly speaking consists of a main body functional section 10, a video display section 20, and an imaging section 30, which are mechanically coupled together and electrically connected. ing. The main body function section 10 includes a speaker 3. Microphone 4. Key button (key manual means)6. A transmitting/receiving circuit 11 connected to the antenna 5, a main control circuit 12. It is equipped with a video system control circuit 13, etc., and the seven control circuits J2 are connected to the speakers 3. Microphone 4° key button 6, video control circuit 13
, and the signal processing circuit 33 of the imaging section 3o. The video display section 20 includes a liquid crystal display 2.
It is equipped with a drive circuit 21 and the like, and the drive circuit 21 receives the video signal sent from the video system control circuit 13, and
The received video is displayed on the liquid crystal display 2. Further, the imaging unit 30 includes a lens system 31
．． Image sensor 32 such as CCD. The signal processing circuit 33 is equipped with a control circuit 34, etc., and is configured to send various video information captured as electrical signals by the image pickup device 32 to the main body functional section 10 via the signal processing circuit 33. Note that the control for photographing by the imaging section 30 may be performed by operating the key buttons 6 of the main body functional section 10, or may be performed by manual operation means provided in the imaging section 30 itself.

In the above configuration, the transmission information received by the antenna 5 is sent from the transmitting/receiving circuit 11 to the main control circuit 12 and discriminated into an audio signal and a video signal, the audio signal is output as audio from the speaker 3, and the video signal is Video system control circuit 13
is sent to the video display unit 20 and displayed on the liquid crystal display 2.
The video information transmitted above is displayed and output as an image. Further, the video information captured by the imaging section 30 is sent to the main control circuit 12 of the main body functional section 10, and the transmitting/receiving circuit 11
is transmitted from antenna 5 via. Furthermore, the audio signal input from the microphone 4 is transmitted to the main control circuit 12. It is transmitted from the antenna 5 via the transmitter/receiver circuit 11.

As mentioned above, if information transmitters have portable radio telephone devices with such a configuration, it becomes possible to mutually transmit video information in addition to audio information, and it is possible to transmit information that is difficult to transmit using audio information alone. It can be accurately and quickly communicated to the other party, and even in an emergency such as an accident, the situation at the scene can be accurately and quickly communicated as a video.

FIG. 3 shows another embodiment of the present invention, in which the portable radio telephone main body 1 can be connected to a large-sized video display device (for example, a CRT display device) 40 via a dedicated cable 41. The image received by the portable radio telephone main body 1 is also displayed on this large image display device 40.

By doing so, the image is enlarged, visibility is improved, and it becomes possible for a large number of people to view the image.

FIG. 4 shows still another embodiment of the present invention, in which the imaging section 30 is configured to be detachable from the portable radio telephone main body 1 on the main flow side, and the imaging section 30 is attached to the portable radio telephone main body 1. When mechanically integrated into the main body 1, both 1 and 30 are electrically connected by a connector 42 (one not shown) and function exactly the same as the embodiment shown in FIGS. 1-22 above. . Furthermore, when the imaging section 30 is removed from the portable radio telephone main body 1, both 1 and 30 are electrically connected with the dedicated cable 43, and the imaging section 30 can be handled independently from the portable radio telephone main body 1. Allows photography. Therefore, operability for photographing is good, and a wide range of objects can be photographed.

The present invention can be modified in various ways other than the embodiments described above.
For example, the video display section 2 may be added to the main body function section 10 described above.
0 or the imaging section 30 may be provided to perform only the reception and display of video information, or only the imaging and transmission of video information. Furthermore, a portable radio telephone having the above-mentioned main body function section 10 may be docked to the function having the video display section 20 and the imaging section 3o to enable mutual video transmission.

〔Effect of the invention〕

As described above, according to the present invention, in a portable radio telephone device, in addition to voice information, information that is difficult to convey by voice alone can be transmitted quickly and accurately as video information, and in particular,
