Abstract

PURPOSE:To obtain an image with which the eyes of a person to be photographed are coincident by displaying the received picture via an optical synthesizer like a half mirror, etc., putting the display surface of the received picture on the photographing surface of a video camera and photographing the eyes the person to be photographed that viewed those received pictures. CONSTITUTION:The light given from a lower CRT 2 is reflected and sent to a right person 4 to be photographed by a half mirror 5 serving as an optical synthesizer. While the light given from the person 4 is transmitted and sent to a video camera 1 at the left side. Thus the person 4 can see the received pictures displayed on a CRT 2 and reflected on the mirror 5 and therefore the camera 1 can photograph the eyes of the person 4 looking at the received pictures through the mirror 5. Thus an image of the person 4 seeing the camera 1 is projected at the remote side. This can eliminate an unnatural image of the person 4 looking at the upper or lower side. A prism is also available as an optical synthesizer in addition to the mirror 5. Furthermore it is possible to transmit the received pictures through the mirror 5 and to reflect the photographed pictures transmitted.

Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to an image transmitting/receiving device such as a video telephone device.

[Prior Art] Fig. 3 is a side sectional view and a front view showing a conventional video telephone device. In Fig. 1, (1) is a video camera, (2) is a cathode ray tube which is a display device, and (3) is a handset. It is.

FIG. 4 is a diagram showing the line of sight of the person to be photographed.

Next, its operation will be explained. First, the user picks up the handset (3) and dials the number, and when the call is established, an image taken by the video camera (1) is transmitted to the called party. Conversely, an image of the other party is sent and received from the other party, and this received image is displayed on the cathode ray tube (2).

When the handset (3) is returned to its original position, one call is completed and both the video camera (1) and the cathode ray tube (2) stop operating.

[Problems to be Solved by the Invention] Since the conventional videophone device is configured as described above, as shown in FIG. I can't look at camera (1). Then, the camera (1) will shoot an image looking down, and both cathode ray tubes (2) will display the image of the person being photographed (4) looking down, which is very inconvenient. There was a problem with being natural.

This invention was made to solve the above-mentioned problems, and aims to provide an image transmitting and receiving device such as a videophone device that eliminates unnaturalness by allowing mutual eye contact. .

[Means for Solving the Problems] The image transmitting/receiving device according to the present invention uses a photosynthesizing device such as a half mirror, the display device displays the received image via the photosynthesizing device, and the video camera monitors the person being photographed. The transmission image is arranged and configured so that the transmitted image is photographed via the above-mentioned optical combining device.

[Function] In this invention, the received image is displayed through a photosynthesis device such as a half mirror, and the transmitted image is photographed. A video camera is used to capture the eyes of the person being photographed, and an image is obtained in which the subject's eyes are visible to both parties.

[Example] An embodiment of the present invention will be described below with reference to the drawings.

Fig. 1 is a side sectional view and a front view showing an embodiment of the present invention, and Fig. 2 is a view showing the line of sight of the photographed person.
) (2) (3) are a video camera, a cathode ray tube which is a display device, and a telephone receiver similar to those shown in FIG. (5)
is a half-mirror which is a photosynthesizer, and the lower cathode ray tube (
2) is reflected in the direction of the right person to be photographed (4), and light from the right person to be photographed (4) is transmitted and directed in the direction of the left video camera (1). It is.

The person to be photographed (4) will see the received image displayed on the cathode ray tube (2) reflected by the half mirror (5), but since the half mirror (5) is arranged as shown in the figure, The camera (1) can transmit through the half mirror (5) and photograph the eyes of the person (4) looking at the received image. Therefore, since the image of the person looking at the video camera (1) is displayed to the other party, the unnaturalness of the image of the person looking upward or downward is eliminated.

In the above embodiment, a half mirror is used as the photosynthesis device, but a prism may be used instead. In addition, the received image is reflected by a half mirror,
Although an example has been shown in which the transmitted photographed image is transmitted, it is also possible to transmit the receiver image and reflect the transmitted photographed image.

Further, in the above embodiment, the case of a video telephone device has been described, but the same effects as in the above embodiment can be obtained even with other still image transmission devices or two-way image transmission/reception devices.

[Effects of the Invention] Since the present invention is configured as described above, it is possible to obtain an image transmitting/receiving device that does not have the unnatural appearance of the photographed person facing upward or downward in the transmitted/received image of the photographed person. have.

[Brief explanation of the drawing]

FIG. 1 is a side sectional view and front view showing an embodiment of the present invention, FIG. 2 is a view showing the line of sight of the person to be photographed, and FIG. 3 is a side sectional view and front view showing a conventional videophone device. FIG. 4 is a diagram showing the line of sight of the person to be photographed. In the figure, (1) is a video camera, (2) is a cathode ray tube which is a display device, (3) is a telephone receiver, (4) is a person to be photographed, and (5) is a half mirror which is a photosynthesis device. The same reference numerals in the drawings indicate the same or corresponding parts.
