Abstract

PURPOSE:To make it sufficient to use one device, to miniturize a receiver/transmitter and to reduce its cost by making it possible simultaneously to display a video to be transmitted by the receiving side as well as to disply a video from the opposite side on one video display part. CONSTITUTION:The titled device displays its transmitting video 11 on an approximate half of a video display part 5 and a video 12 from the opposite side on the remaing screen. A video signal made in an image-pickup part 6 is transmitted to a transmitting line 7 and directly inputted to a converting part 15 at the right side through a mirror image converting part 13 or by switching a switch 14. Then the video signal is displayed on the right part of the video display part 5. On the other hand, a video signal from the opposite party is displayed on the left part of the video display part 5 through a transmitting line 3, a converting part 17 at the left side and a synthesizing pat 16. A mirror image converting part 13 has a function to make the self video 11 displayed on the video display part 5 into a mirror image with respect to an original picture.

Description

[Detailed Description of the Invention] A video transmitting/receiving device ((
It is related to.

When transmitting and receiving images to and from a remote party, a configuration similar to that shown in FIG. 1 is generally used.

In other words, in FIG. 1, the image 1a of the other party that comes out from the imaging unit 2 of the other party 1 is sent to the image display unit 5 of the own side 4 via the transmission path 3.
will be displayed. Also, the video signal from the own side 4 outputted from the image pickup section 6 of the own side 4 is displayed on the video display section 8 of the other side via the transmission path 7.

However, in the case of the configuration shown in Figure 1, the self-side 4
The disadvantage is that it is not possible to check the image on the own side that is output from the imaging unit 6 of the camera. That is, it is unclear whether the self-side imaging unit 6 is operating normally and how it is viewed by the other party. Some improved methods are also known.

These will be explained with reference to FIGS. 2 and 3. In the system shown in FIG. 2, another sleeping image display section 9 is provided on the self-side 4, and the self-image signal outputted from the self-011 imaging section 6 is sent to the transmission path 7, and the self-image display section 9 is Also display self II)
] so that you can check the video. This method does not have the disadvantage that it is not economical because two video display units are required, and that the entire device becomes large.

The method shown in FIG. 3 is to install a mirror 10 on the imaging unit 6 on the own side and check the image being transmitted by the imaging unit by looking at the image reflected in the mirror. . Although this method is economical, it has the disadvantage that it is inconvenient, such as not knowing if the imaging unit 6 is out of order.

The purpose of the present invention is to eliminate the drawbacks of such conventional video transmitting and receiving devices.Specifically, it is possible to display the video from the other party on one video display unit, and at the same time to transmit the video from the own side. The present invention is intended to eliminate the above-mentioned drawbacks of the conventional technology by making it possible to display even images that are currently being displayed. That is, as shown in FIG. 4 and FIG. 5, half of the entire screen of the video display device 5,
Alternatively, a portion of the screen (() is to display an image 11 of the user's own message, and display an image 12 from the other party on the remaining screen.

FIG. 4 shows a complete block diagram of an embodiment of the present invention and will be described.

One embodiment shown in FIG. 4 is to display the video 11 being transmitted by itself on approximately half of the ID video display section 5, and display the video 12 from the partner side on the remaining screen. In FIG. 4, the video signal produced by the imaging section 6 is sent to the transmission line 7, and is also input to the right conversion section 15 through the mirror I-image conversion section 13 or directly by switching the switch 14, and is input to the synthesis section 16. The image is then displayed on the right side of the video display section 5. On the other hand, the video signal from the other party is displayed on the left side of the video display section 5 via the transmission line 3, the left conversion section 17, and the synthesis section 16. The mirror image conversion unit 13 has the function of converting the self-image 11 displayed on the video display unit 5 into a mirror image of the original image. Since it is displayed as if there is a real person, there are many cases where it is more attractive to display it like that, and there are also cases where it is easier to use, so it is done this way.

A second embodiment of the present invention is shown and explained in FIG.

In the example shown in FIG. 5, the configuration is such that the transmitted video 11 from the own side is displayed in about the lower right quarter of the entire screen. The signal passes through the mirroring device 13 or through the switch 14.
By switching the signal, the signal enters the reduction conversion unit 18 directly, is combined with the signal from the reception unit in the synthesis unit 16, and is displayed on the video display unit 5 at the bottom right of the input screen.

In the third embodiment shown in FIG. 6, the entire screen of the video display section 5 is divided into four parts, and the video 1112 from the other party is displayed in the upper left, and the video 11 from the own side is displayed in the lower right. Other video output devices 21 are located at the lower left 19 and upper right 20 of the screen, respectively.
It is possible to display images from 22 and 22.

Video output devices include TV tuners, V1's,
Character mouth type display device used in computers, etc.
Alternatively, it is a device that outputs a video signal, such as an imaging device.

The output from the video output device 521 enters the synthesis section 24 via the reduction conversion section 23 and is displayed at the lower left of the video display section 5.

The output from the video output device 22 passes through the reduction conversion section 25, enters the synthesis section 24, and is displayed on the right side of the video display section 5.

26 and 27 are also reduction converters, and the other operations are performed by the fifth
It is similar to the figure.

As explained above, the gist of the present invention is to receive a video signal from the other party and display the video of the person sending the message as a mirror image or a normal image on a part of the video display unit. With this, only one video display unit is required, making the transmitter/receiver more compact and economical, and it is also possible to monitor the self-transmitted video without moving your line of sight while viewing the other party's video. It has the effect of being convenient.
