JPH0583701A - Picture transmitter - Google Patents

Abstract

PURPOSE:To prevent a sense of disorder by placing an image pickup camera to a same position as a screen so as to match a sight line of sent own picture with an eye of the observer. CONSTITUTION:When the operator desires to send its own picture to an opposite party, the operator depresses an operation button 6. A signal processing section 4 selects a reception circuit to a transmission line signal 101 to a transmission circuit by using a transmission control signal 102. Moreover, a control section 5 interrupts a video signal to a display section 1 to darken the screen and sends a signal to a camera section 3, its shutter is operated and the image is picked up. Since the screen is dark, the image pickup light from its own picture of the operator is reflected in a mirror 2 at an angle of 45 deg. downward and enters a lens of a camera 3, The video signal from the camera 3 enters the signal processing section 4 and is sent to the opposite party as a transmission line signal by a transmission circuit.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an image transmission device, and more particularly to a video telephone device and a video conference device for transmitting a self-portrait to the other party.

[0002]

2. Description of the Related Art Conventionally, in this type of image transmission device, the screen of the display unit for displaying the image of the other party and the lens of the camera unit for taking a self-portrait are arranged adjacent to each other. That is, the operator presses an operation button as necessary while looking at the screen of the display unit, thereby taking a self-portrait with the lenses of the camera units arranged next to the screen of the display unit and sending the self-portrait to the other party.

[0003]

As described above, in the conventional example, since the screen of the display unit and the lens of the camera unit are in a position adjacent to each other but in a position apart from each other, the image is photographed while watching the image. When the other party sees the self-portrait on the other party's screen, there is a problem in that the eyes of the image give a sense of discomfort because the other person's eyes are not looking.

[0004]

The image transmitting apparatus of the present invention is provided with a display unit for receiving a partner image signal and displaying the partner image, and a display unit installed at a position in front of the screen of the display unit at an angle of 45 °. Light from the screen of the display unit is transmitted, and a mirror that reflects light from the operator side at an angle of 45 ° in response to a switching signal from the operator who sees the screen, and a self-portrait of the operator that receives reflected light from the mirror And a camera unit for transmitting this image signal to the other party.

The mirror may reflect light from the operator side at an angle of 45 ° by shutting off the image on the display unit and darkening the screen in response to a switching signal from the operator.

[0006]

Next, an embodiment of the present invention will be described with reference to the drawings. FIG. 1 is a configuration diagram showing the configuration of this embodiment.
This image transmission apparatus includes a display unit 1 mainly composed of a picture tube, a mirror 2 installed at a position in front of the screen of the display unit 1 at an angle of 45 °, and an image on the operator 7 side reflected by the mirror 2. The camera section 3 for taking a picture, the reception of the transmission path signal 101 from the other party, the transmission of the self-portrait signal from the camera section 3, the operation button 6 which the operator 7 presses at the time of photographing, the processing of the video signal and the transmission A signal processing unit 4 for switching between transmission and reception to the road, and a control unit 5 for transmitting a signal for pressing the shutter of the camera unit 3 after shutting off the video signal to the display unit 1 to darken the screen, The screen portion of the display unit 1, the mirror 2, and the lens portion of the camera unit 3 are covered with a cover 8 and a transparent cover 9.

The operator 7 sees the image sent from the other side of the display unit 1, but since the image light at this time passes through the mirror 2, there is no problem in seeing the image. Next, when the operator wants to send the self-portrait to the other party, the operation button 6 is pressed. As a result, the transmission control signal 102 is input to the signal processing unit 4, the signal processing unit 4 switches the reception circuit for the transmission path signal 101 to the transmission circuit, and at the same time transmits the transmission control signal 102 to the control unit 5. The control unit 5 cuts off the video signal to the display unit 1 to darken the screen, and then sends a signal to the camera unit 3 to turn off the shutter and photograph. Since the screen is dark, the image pickup light from the operator is reflected by the mirror 2 downward 45 ° and enters the lens of the camera 1.

A video signal from the camera 1 enters a signal processing section 4 and is transmitted to the other party as a transmission path signal 101 by a transmission circuit here. The method of switching between the transmitted light and the reflected light of the mirror 2 may be another method, for example, the mirror itself is switched to the reflected light by blocking the transmitted light by applying a voltage according to a control signal from the control unit 4 like a liquid crystal. You can use the same method.

[0009]

As described above, according to the present invention, the camera for photographing is placed at the same position as the screen by the reflection mirror placed in front of the screen. Therefore, if you take a self-portrait while looking at the screen of the display unit, when you look at this image on the other side, you will not feel discomfort to the other side because the eyes of the image are looking at the other side, The effect is that it can be transmitted.
