Abstract

PURPOSE:To allow mutual speakers to speak each other while allowing mutual eyes to meet with each other by picking up an image by a means for dividing light into transmitted light and reflected light and matching the optical axis of a means for converting the picked-up image into an electric signal with that of a means for converting the electric signal into a picture. CONSTITUTION:The titled device is provided with a TV camera 1, a TV image receiver 2, a haif mirror for dividing light into transmitted light and reflected light and matching the optical axes of both the light components and a case body 4 for surrounding said three means to shield unnecessary light and provided with a window for light inlet/outlet port on a part of it. The light of an image made incident from the window of the case body 4 is divided into transmitted light and reflected light by the half mirror 6 and the reflected light is picked up by the TV camera and converted into an electric signal. On the other hand, the light of a picture projected on the TV image receiver is projected to the outside through the half mirror 3. When an originating speaker observes the picture of a terminating speaker through a TV telephone, his eyes are turned to the eyes of the terminating speaker.

Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a device that enables conversation while viewing images of each other's faces, such as a device that is useful for videophone calls.

[Prior Art] Conventionally, in a videophone, as a device for transmitting and receiving images, a television camera that captures and transmits an image and a television receiver that receives the video signal of the other party are located at different locations, that is, on the two optical axes. was arranged from a different angle.

[Problem that the invention attempts to solve] Therefore, there are the following problems.

For example, assume that Party A and Party B are talking on a conventional videophone call. Since Party A is looking at the television receiver to see Party B's face, Party A's line of sight is not toward the television camera that is filming Party A. Therefore, Party B's line of sight is directed towards the TV receiver, that is, towards himself. You will have to look at A's face when you speak. This is the same from the perspective of the person in question, and both parties must speak without looking at each other, which is extremely unnatural and extremely difficult to talk to.

SUMMARY OF THE INVENTION An object of the present invention is to provide an imaging video device that allows users to talk while looking each other in the eye during a videophone call.

[Means for solving the problem] This method consists of a means for dividing light into transmitted light and reflected light, a means for capturing an image and converting it into an electrical signal, a means for converting the electrical signal into an image, and a means for separating unnecessary light. imaging in which the optical axis of the means for capturing an image and converting it into an electrical signal is aligned with the optical axis of the means for converting the electrical signal into an image by means for dividing the light into transmitted light and reflected light. It is a video device.

[Function] Since the present invention has the above-described configuration, when this is used for a videophone call, if the other party is looking at the image, the image will inevitably be captured and an electrical signal will be transmitted. This means that we are looking towards ways to convert it into .

[Example 1] FIG. 1 is a schematic diagram showing the configuration of a video telephone imaging device according to an example of the present invention.

A television camera 1 serves as a means for capturing an image and converts it into an electrical signal, a television receiver 2 serves as a means for converting the electrical signal into a video, and a half mirror serves as a means for dividing light into transmitted light and reflected light and aligning the two optical axes. 3. As a means for blocking unnecessary light, a casing 4 is used which surrounds the three means and has a window for light entrance/exit.

The image light entering through the window of the housing 4 is divided into transmitted light and reflected light by the half mirror 3. The reflected light is imaged by the television camera 1 and converted into an electrical signal. On the other hand, the light of the image projected on the television receiver 2 passes through the half mirror 3 and comes out.

[Effects of the Invention] Since the present invention has the above-described configuration, when the present invention is used for a videophone call, if the person having the conversation is looking at the image of the other party, the image will inevitably change. This means that it is facing the means of capturing images and converting them into electrical signals. This means that your gaze is directed toward the person you are talking to. Therefore, the parties can talk while looking each other in the eye, which makes it very easy to talk, and the conversation progresses smoothly, shortening the call time.

[Other Examples] The same effect can be obtained even if the positional relationship between the television camera 1 and the television receiver 11!2 is reversed.

Moreover, instead of the half mirror 3, a prism 5, which is formed by matching the hypotenuse surfaces of two right triangular prisms, may be used.

Also, considering the shape of the equipment used such as the television camera 1 and the television receiver 2, and the shape of the housing 4, a total reflection mirror 6 is provided and the positional relationship between the television camera 1 and the television receiver 2 is changed. The left and right scanning directions of the television camera 1 and television receiver 2 must be reversed in this case because the left and right sides of the image are reversed depending on the number of times the image is reflected by a mirror or the like. Not even.

FIG. 1 is a schematic diagram showing an embodiment of the present invention. FIGS. 2, 3, and 4 are schematic diagrams showing other embodiments.

Claims (1)

[Claims] It is equipped with a means for dividing light into transmitted light and reflected light, a means for capturing an image and converting it into an electrical signal, a means for converting the electrical signal into an image, and a means for blocking unnecessary light.
