Description

[Detailed description of the invention] The present invention is a video conferencing device suitable for holding a conference between two people at two separate locations. This invention relates to an improvement in a television conference device that reproduces images separately on the screens of two receivers.

In a conventional television conference device, participants gazing at the screen of a television receiver are imaged by a television camera installed above the television receiver. For this reason, the captured image of the subject person tends to have downcast eyes, which has the disadvantage of significantly impairing the naturalness of the meeting.

An object of the present invention is to provide a video conference device that has improved these drawbacks to a considerable extent.

In other words, the video conferencing device according to the present invention divides the received image sent from the other party into upper and lower halves,
In a video conferencing device that has an image reproduction method that separates the upper half and lower half of the image and displays each of these separated images independently on the center portions of two receivers, each of the image receiving sides A reflector is installed at a position on the image sending side that corresponds to the unnecessary upper part of the screen that is separated and displayed by the two receivers on the side, and the object located in front of the receiver is reflected on the TV through the reflective border. This is a video conferencing device configured to capture images with a camera.

DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, embodiments of a video conference device having an imaging function according to the present invention will be described with reference to the drawings.

FIG. 1 shows a side view of an embodiment of the present invention. In FIG. 1, a television camera 2 installed on the top of a television receiver 1 is connected to a plane reflecting mirror 3 installed just in front of the television camera, and a plane reflecting mirror 3 installed directly in front of the television camera, and an effective vertical direction of images separately displayed on the television receiver screen. An image of a person to be photographed 5 is captured through a flat reflecting mirror 4 located immediately in front of the picture tube surface excluding a portion a. By adjusting the angles of the plane reflecting mirrors 3 and 4, the vertical imaging range of the subject can be adjusted.

When the image is captured in this way, the angle θ between the line of sight b of the person gazing at the image a on the receiver surface and the imaging line c where the television camera captures the eye is the angle θ from the receiver to the plane It is clearly smaller than the angle θ' with the imaging line c' when the image is directly captured without using a reflecting mirror, and it is possible to provide a television conference device that improves the above-mentioned drawback of parallax.

Furthermore, in this type of split-screen imaging system, two television cameras are conventionally installed on the receiver, one of which captures the image of one group of participants in the upper half of the camera's imaging range, and the other. One of the cameras adjusted the vertical tilt of the TV camera, or adjusted the center of vertical deflection within the TV camera, so that the image of the participants in the other group was captured in the lower half of the camera's imaging range. However, according to the present invention, the TV camera remains fixed horizontally,
Another advantage is that the imaging range in the vertical direction can be easily adjusted by simply changing the inclinations of the plane reflecting mirrors 3 and 4.
