Abstract

PURPOSE:To reproduce and display the image of a subject simply stereoscopically by dividing a video image of the subject into plural pictures in response to the distance from an image pickup camera to each point of the subject and reproducing and displaying the images onto each of laminates of plural thin film liquid crystals of a display section respectively. CONSTITUTION:A subject 1 is irradiated with plural electromagnetic wave beams to measure a distance from an image pickup camera 2 to each point of the subject 1 based on a reflecting wave of the electromagnetic wave beams from the subject 1. The obtained distance and the subject video image are converted respectively into a distance signal and a video signal and they are sent from a transmitter 4 with synchronization. The distance signal and the video signal sent from the transmitter 4 are given to a receiver 5, in which the video image is divided into plural pictures corresponding to the distance from the image pickup camera 2 to each point of the subject 1 and the pictures are reproduced and displayed onto each liquid crystal thin film of a liquid crystal thin film layer 3a. Thus, the picture is simply reproduced stereoscopically and visually recognized as a natural body.

Description

[Detailed Description of the Invention] <Industrial Application Field> The present invention relates to a method and apparatus for reproducing and displaying a subject as a three-dimensional image when photographing an object with a photographing device and reproducing and displaying it on a reproducing display device. .

<Conventional technology> Conventionally, photographic equipment for movies, television, still photography, etc.
A reproduction display device is a device that reproduces and displays an image of a subject photographed and recorded on a flat surface such as a film or magnetic stave using a photographing device on a reproduction display screen such as a screen or cathode ray tube using a reproduction display device such as a television receiver. The visual angle, which occurs based on the distance of the subject, is displayed by replacing it with the distance on the plane of the playback display screen, and the displayed image is created as if the image of the subject was created by human imagination. Although it can be perceived as being reproduced and displayed three-dimensionally, it is not just a three-dimensional image of the subject, and sometimes the perspective may be reversed depending on how you perceive the subject.

In addition, called 3D photography and 3D movies, images are taken using a pair of polarized lenses as if viewed with the human eye.
There is also a method of reproducing and displaying the image by superimposing it on two reproduction display screens, and wearing polarized glasses to obtain the same viewing angle as the subject, thereby allowing the image of the subject to be recognized three-dimensionally. These 3D photographs and 3D movies reproduce and display objects in 3D, but the problem is that they require the user to wear polarized glasses.

There is also a method called laser holography that uses optical interference, but it has the problem that the device is complicated and large-scale.

<Problem to be solved by the invention> Conventional film/television still photography, stereoscopic photography/stereoscopic movies, and laser holography have the problems described above, so it is not easy to convert the image of the subject into three-dimensional images. There is a need for a means that can reproduce and display images.

An object of the present invention is to provide a method and apparatus for photographing and displaying a three-dimensional image, which solves the above-mentioned problems.

(Means for solving the problem) This will be explained with reference to Figure 1.In order to achieve the above purpose,
The method of photographing and displaying a stereoscopic image according to the present invention divides an image of a subject l into a plurality of images corresponding to the distance from a photographing camera 2 to each point of the subject, and divides the image of a subject l into a plurality of images, and The images are reproduced and displayed on the laminate 3a of the images.

More specifically, a plurality of electromagnetic beams are irradiated onto the subject 1, and the distance from the camera 2 to each point on the subject 1 is measured based on the reflected waves of the electromagnetic beams from the subject 1. The distance signal and the image of the subject are converted into a distance signal and a video signal respectively, and the signals are synchronized and transmitted by the transmitter 4, and the distance signal and video signal transmitted from the transmitter 4 are received by the receiver 115, and the video is converted into a distance signal and a video signal. The image is divided into a plurality of images corresponding to the distance from the photographing camera 2 to each point on the subject 1, and the images are reproduced and displayed on each liquid crystal thin film of the liquid crystal thin film stack 3a.

The stereoscopic image photographing/displaying device according to the present invention irradiates a plurality of electromagnetic wave beams onto a subject 1, and calculates the distance from a photographing camera 2 to each point on the subject 1 based on the reflected waves of the electromagnetic wave beams from the subject 1. The distance and object image obtained from a photographing device equipped with a distance measuring means 2a to be measured, a display unit 3 equipped with a liquid crystal thin film laminate 3a, and a photographing camera 2 are converted into a distance signal and a video III signal, respectively, and are synchronized. , transmitter 4, distance 11141 transmitted from that transmitter 4
It consists of a receiver 4 that divides the number M and the video signal into a plurality of images corresponding to the distance from the photographing camera 2 to each point of the subject l, and reproduces and displays them on each liquid crystal thin film of the liquid crystal thin film stack 3a. Effect> As described above, the three-dimensional image photographing/displaying method and apparatus configured as described above divide the image of the object into a plurality of images corresponding to the distances from the photographing camera to each point of the object, and display each image of the liquid crystal thin film laminate 3a. Since it can be reproduced and displayed on each liquid crystal thin film, it gives depth to the image, reproduces the image three-dimensionally, and allows it to be viewed as a natural object.

<Example> An example will be described with reference to FIG. 1. l is a subject, 2 is a camera that photographs the subject 1, and 3 is a three-dimensional playback display of an image of the subject l photographed by the camera 2. This is a display section equipped with a liquid crystal thin film laminate 3a. Note that 3b is a speaker. Shooting camera 2
has a built-in distance measuring means 2a that measures the distance to each point of the subject, and emits a ranging electromagnetic wave such as an infrared beam toward the subject 1, and
By receiving the reflected waves, it is possible to measure the distance to each point on the subject 1 based on the round trip time from emission to reception.

Reference numerals 4 and 5 denote a wired or wireless transmitter and receiver for transmitting and receiving necessary signals from the photographing camera 2 to the display unit 3, respectively.

Next, the effect will be explained. A photographing camera 2 is aimed at a subject 1, a distance measuring electromagnetic wave such as an infrared beam is emitted from a distance measuring means 2a, and a photograph is taken while measuring the distance to each point on the subject 1. In this case, the ranging electromagnetic waves are emitted from a plurality of different positions of the photographing camera 2 in order to reproduce the image three-dimensionally.

The distance and video obtained by the photographing camera 2 are synchronized, and the transmitter 4 converts them into distance signals, video signals, and audio signals using electricity or light, respectively, and transmits them to the receiver 6 along with audio. The receiver that has received the distance signal, video signal, and audio signal divides the distance signal and video signal into a plurality of images according to the distance to each point of the subject, and reproduces them on each liquid crystal thin film of the liquid crystal thin film stack 3a. . Therefore, images can be reproduced three-dimensionally, giving them depth and making them visible as natural objects. Note that the audio signal is reproduced as audio by the speaker 3b, giving the viewer a more realistic feeling.

Note that a plurality of photographic cameras 2 may be used to measure distances from a plurality of different locations and send signals to the transmitter 4, respectively.

In addition, the present invention is also applicable to CAD/computer graphics.

(Effects of the Invention) Since the present invention is configured as described above, compared to conventional movies, televisions, still photographs, etc., images can be reproduced three-dimensionally, given depth, and visually recognized as natural objects. can do.

Additionally, compared to stereoscopic photographs and movies, viewers can easily view stereoscopic images without the distraction of wearing polarized glasses.

Furthermore, compared to laser holography, the equipment, especially the receiving/reproducing/displaying equipment, is simple and small-scale, making it easier for viewers to accept it.
