Abstract

PURPOSE:To make the monitor screen large and to attain display of the screen for the plural number of sheets by incorporating a video telephone set main body except a handset and a camera section to a television receiver having a memory in its inside, making the camera section independent and connecting the camera section to the television receiver with a cord. CONSTITUTION:A video telephone pattern is displayed as a slave pattern onto a part 101 of a display screen of an EDTV 10, a cord 10 is drawn from the rear face of the EDTV 10 and a camera section 12 is provided to the tip of the cord. For example, a signal of a picture picked up by a camera 122 at proper lighting and proper aperture is sent to the video telephone main body section 13 of the EDTV 10 through the cord 11. While a memory incorporated in the EDTV 10 is used in common, the signal is processed similarly in a conventional device and sent to the opposite party. Thus, both the picture picked up by the camera section 12 and the picture sent from the opposite side are displayed on the screen of the EDTV 10 as two slave patterns.

Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial Application Field] The present invention relates to a video telephone device using a television receiver having an internal memory, such as an IDTV or an EDTV.

[Conventional technology]

In addition to a telephone device, a video telephone device is equipped with an image transmitting/receiving unit consisting of a camera, a screen, and an operation unit for imaging/displaying/transmitting, and can transmit still images between parties to the conversation.

FIG. 6 is a diagram showing the general structure of the video telephone device. In this device, when a dial on a telephone 1 is operated, an audio/image switching circuit 2 connects a line to a specific party via a line interface 3. After this, on the sending side,
The image information captured by the camera 4 is sent to the monitor 6 by the control unit 5.
When the transmit button (not shown) is operated, the audio/image switching circuit 2 switches from the voice communication state to the image transmission state, and the transmission image data is subsequently transmitted by the control unit 5. The signal is read out from the memory 7, subjected to amplitude and phase modulation by the modulation circuit 8, and sent out to the telephone line. On the other hand, on the receiving side, the still image signal is identified from the received audio signal, the audio/image switching circuit 2 is switched from the voice communication state to the still image reception state, and the received image is demodulated by the demodulation circuit 9 and stored in the memory 7. Store in. and,
Based on this stored image data, the image is displayed on the monitor 6.

[Problem to be solved by the invention]

However, the monitor screen of this device is generally small, perhaps because it is compatible with telephone devices, and the number of images displayed is limited to one. Furthermore, since this device does not have a light source, consideration must be given to the installation location.

The present invention has been made in view of these points, and its purpose is to solve the above-mentioned problems.

[Means to solve the problem]

To this end, the present invention incorporates the main body of the video telephone device excluding the handset and camera section into a television receiver having an internal memory, and connects the camera section to the television receiver using a cord.

In this invention, an illumination lamp can be provided in the camera section.

〔Example〕

Examples of the present invention will be described below. FIG. 1 is a diagram schematically showing a video telephone device according to one embodiment. In this embodiment, the videophone screen is displayed as a sub-screen on a part 101 of the display screen of the EDTV 10, and the cord 11 is pulled out from the back side of the EDTV 10, and the tip of the cord 11 is A camera section 12 was provided. The videophone main unit 13 is incorporated into EDTVIO by sharing its memory. However, the handset (not shown) is now removable from the EDTV 10.

FIG. 2 is a diagram showing details of the camera section 12.

This camera section 12 includes a CCD and a
A camera 122, two illumination lamps 123, a reflector 124 surrounding the illumination lamps 123, and a light receiving element 125 are provided, the operating end 126 is pulled out with a cord 127, and the aforementioned cord 11 for power supply and signal extraction is connected to the plug 111. ED
It is designed so that it can be connected to the terminal on the back of the TV 10.

FIG. 3 is a diagram showing internal blocks of this camera section 12. The light receiving element 125 detects the brightness on the front side of the camera 122, and this detection signal causes the camera 12 to
2 automatically adjusts the aperture.

In this embodiment, by turning on the switch 1261 of the operating end 126, power is applied to the light receiving section 125, camera 122, and lamp 123, and they operate.

With this, camera 1 can be adjusted with appropriate lighting and appropriate aperture.
The image signal captured by the HDTV 10 is sent via the code 11 to the videophone main unit 13 on the EDTV 10 side, where it is processed in the same way as before while sharing the memory built into the HDTV 10. and sent to the other party. Note that switching between transmission to the other party and reception from the other party is performed by operating the image transmission/reception switch 1262.

Here, since an EDTVIO is used as a monitor in this embodiment, both the image captured by the camera unit 12 and the image sent from the other party are displayed on this EDTV 10.
can be displayed as two sub-screens on the screen. Furthermore, if the memory for storing images has a sufficient capacity, a plurality of images taken in the past by the camera unit l2 and a plurality of images received from the other party can be simultaneously displayed on the EDTVIO.

FIG. 4 is a diagram showing another example of the camera section 12.

Here, a fluorescent lamp 1 with lighting lamps 123 arranged horizontally is shown.
23', a reflector 124' having a similar shape is placed around it.
are installed to provide sufficient lighting. FIG. 5 is also a diagram showing another example of the camera section 12, in which a semicircular fluorescent lamp 123'' is used and a reflecting plate 124'' of the same shape is provided around the fluorescent lamp 123''.

Note that here, the cord 127 is pulled out from the camera unit 12, and an operating end 126 is provided at the tip to control the camera unit 12 and switch between image transmission and reception. Since the cord 127 cannot be separated, the length of the cord 127 is also approximately the same.

However, if a cordless type handset is used, the handset can be placed quite far away from the main body of the telephone, so in this case, the cordless handset can be connected to the operating end 126.
Provide a button that performs the same function as .

In addition, although still images were targeted here, if a large-capacity line is used, videos can also be sent and received, and in this case, switching between video and still images is also required.
This switching is also performed using the operating end 126 or a cordless handset provided with the operating end 126.

〔Effect of the invention〕

As explained above, according to the present invention, structural elements other than the handset and camera section are incorporated into a television receiver having an internal memory, and the camera section is made independent and connected to the television receiver by a cord, so that the monitor The screen can be made larger and multiple images can be displayed. Also, by providing a light source to the camera, it is possible to perform proper exposure, and it is possible to capture good images and send them to the other party.
