Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a TV telephone and a TV set.
The present invention relates to a display and imaging device in which a display device and an imaging device used for a conference system or the like are combined.

[0002]

2. Description of the Related Art T which connects remote locations with a video / audio communication network
Two-way video communication such as a V-phone and a TV conference system has been widely used.

[0003] Various combinations of a display device and an imaging device used for such two-way video communication have been proposed. An imaging device is disclosed in Japanese Patent Application Laid-Open No. 6-30406 (Int. Cl. H04N 7/14). In this device, a projection type display device is arranged in a viewing direction in which light is scattered by using a screen having a function of being transparent or scattered depending on an incident angle of light, and displays a received projection image of the other party. At the same time, the camera is arranged in a transparent viewing direction, and a user watching the screen is imaged through the screen. In this way, by capturing the user through the screen, the eyes of the interlocutor are matched.

[0004]

In the above-mentioned conventional apparatus, it is assumed that the user is looking at the center of the screen, and the user who is assumed to be at that position is imaged by the camera. . For this reason, when there are multiple users, not only cannot the eyes be matched, but also natural eye contact with the interlocutor is not possible, such as capturing an image of a place where no one is present or a person who is not interacting. was there.

SUMMARY OF THE INVENTION An object of the present invention is to provide a display and imaging device capable of natural eye contact in view of the above-mentioned conventional problems.

[0006]

According to the present invention, there is provided a projection image apparatus, an image pickup apparatus, and a screen having a function of being transparent or scattered according to an incident angle of light. It is a display and an imaging device in which an imaging device is arranged in an incident angle direction through which light is transmitted, and a moving unit that moves the imaging device, and a detection unit that detects a user, Moving the imaging device by the moving means in the direction detected by the detecting means,
It is characterized in that the user is imaged.

Further, according to the present invention, the image light from the projection image device is reflected and guided to a screen by using a half mirror, and the image pickup device is arranged in a direction in which the light of the half mirror is transmitted. .

[0008] According to the above configuration, since the image pickup apparatus automatically turns to the user, natural eye contact can be obtained.

[0009]

Embodiments of the present invention will be described below with reference to the drawings. FIG. 1 is a schematic cross-sectional view of a display and imaging device according to the present invention as viewed from the side.
1 is a schematic cross-sectional view of a display and imaging device according to the present invention as viewed from above, and FIG. 3 is a block diagram showing a configuration of the present invention.

The display and image pickup device of this embodiment is obtained by providing a rear projection display device with a CCD camera as an image pickup device.

As shown in FIG. 1 and FIG.
A housing 2 and an image projection device 3 arranged at the bottom in the housing 2
And a reflection mirror 4 that totally reflects the image light projected from the image projection device 3, and a screen 1 that receives the image light reflected by the reflection mirror 4 from the back side and diffuses and emits it to the front side. .

The above-mentioned screen 1 is formed of a transparent substrate having a visual field selection function, for example, an angle 2 manufactured by Nippon Glass Co., Ltd. The transparency / scattering can be controlled by the incident angle of light. it can. The above-mentioned reflection mirror 4 is constituted by a half mirror that reflects the image light from the image projection device 3 and transmits the light from the back surface.

The angle at which the image light is reflected by the reflecting mirror 6 and is applied to the screen 1 is set so that the light is scattered with respect to the screen 1. Further, a CCD camera 3 as an image pickup device is provided on an extension of an angle that becomes transparent to the screen 1 and on the back surface of the reflection mirror 6.

Therefore, the users 10 and 11 are required to
The image projected from the image projection device 3 via the reflection mirror 4 for guiding the image light from the direction in which the light is scattered, and projected on the screen 1 is observed. The CCD camera 5 captures an image of the user 10 (11) looking at the screen 1 from a direction transparent to the screen 1.

In the present invention, the CCD camera 5 is mounted on a mount table, and is controlled to be movable by a monitor driving device 6. The operation of the monitor driving device 6 is controlled by a control unit 7 composed of a microcomputer or the like.

On the left and right sides of the apparatus, there are provided sound sensors 8 as user detecting means for detecting which user is speaking. The outputs of the left and right sound sensors 8a and 8b are given to the control unit 7. Can be The control unit 7 determines which user is speaking at which position based on the output values of the sound sensors 8a and 8b, operates the monitor driving device 6 so as to image the position, and operates the CCD camera 5.
In that direction.

For example, when the user 11 is interacting as shown in FIG. 2, the output of the sound sensor 8b increases,
The control unit 7 determines the user 11 and its position based on the output difference between the sound sensors 8a and 8b, and operates the monitor driving device 6 so as to direct the CCD camera 5 in that direction.

As a result, the user 11 (1)
The shape of 0) passes through the screen 1 and the reflection mirror 4,
Since the image can be captured by the CCD camera 5 arranged behind the screen 1, it is possible to have a conversation with the interlocutor displayed on the screen 1 in a staring manner.

Further, according to the present invention, the CCD camera 5 is automatically controlled to face the speaker by the output of the sound sensor 8, so that the T
Eye contact is also possible at the V conference.

In the above-described embodiment, the speaker is detected by the sound sensor 8.
The motion may be detected based on an image from the camera 5 and the CCD camera 5 may be controlled to move in accordance with a moving person.

In the above embodiment, the case where the present invention is applied to the rear projection type display device in which the projection light is guided to the screen side by the reflection mirror has been described. Of course, the present invention can be applied to a projection display device.

[0022]

As described above, according to the present invention, since the CCD camera is automatically turned to the direction of the user (speaker) and takes an image of the user, the TV of a plurality of attendees is displayed.
Natural eye contact can also be taken at meetings and the like.
