Abstract

PURPOSE:To easily correct the distortion of a reproduced image by providing a shield member which prevents a view-point side hologram from being irradiated with light from a white light source and a concave reflecting mirror which is curved along a hologram on the opposite side from the view point. CONSTITUTION:The shield member 8 is provided to a base 3 so that the half of a hologram cylinder 1 on the view-point side is not irradiated with light from the white light source 4, and the concave reflecting mirror 9 which is curved along the opposite side of the outer periphery of the hologram cylinder 1 from the view point is also provided. A hologram image is therefore reproduced with the hologram on the opposite side from the view point of the hologram cylinder 1 and the reproduced image 6 is reflected by the concave reflecting mirror 9 to enter the eyes of an observer 7. Consequently, the reproduced image 6 is enlarged horizontally to correct its distortion and a perspective image which is large on the front side is obtained by the concave reflecting mirror 9.

像を観察することができる。(Prior Art) Conventionally, a white light reproducing cylindrical holographic stereogram called a "multiplex hologram" has been put into practical use as one of three-dimensional image display means. This multiplex hologram reproduction device is equipped with a device that allows a three-dimensional image of the subject to be viewed inside a hologram cylinder having an axis extending in the vertical direction.
By rotating the hologram cylinder around the axis, three-dimensional images of the subject viewed from all directions around the axis can be viewed continuously. To create such a multiplex hologram, first place the subject on a turntable, photograph the subject with a cine camera while rotating the turntable, and create a series of original images (i″f, Next, using an optical system consisting of a projection lens, a field lens, and a cylinder lens, and a reference light, each frame of this cine film is continuously printed on a hologram film as a hologram that is stretched vertically through a slit. This hologram film is shaped into a cylinder to create a hologram cylinder, and when this hologram cylinder is illuminated with white light from above or below, a three-dimensional image of the object floating inside the hologram cylinder can be observed.

It has a cylindrical shape and is mounted on a base 3 so as to be rotatable around an axis 2 extending in the vertical direction.

あった。By the way, in principle, the reproduced image in the white light reproduction cylindrical holographic stereodulum described above is
As shown in FIG. 8, it is known that the vertical direction of the image is distorted as if it had been stretched, making it appear truncated. Furthermore, as shown in Figure 9, the vanishing point in perspective painting comes to the front of the image and objects behind appear larger, resulting in the so-called reverse perspective phenomenon. It is also known that there is a drawback that the reconstructed image becomes unrealistic, since even the holograms created by the image can be seen at the same time. Especially when the subject is a car,
The beauty of the car's body shape could not be reproduced, making it unsuitable as a display.Therefore, as a countermeasure to correct the above-mentioned distortion, (1)
Using a lens, the original image is given a reverse distortion in advance.
(2) Processing such as correcting the original image using a computer is performed when creating the hologram film. However, the measure (1) above has the disadvantage that noise increases due to the chromatic aberration of the lens used, and the measure (2) above has difficulty correcting complex images unless a large-capacity computer is used. However, there was a problem in that the production cost was also high.

に適した構成であると言うことができる。(Effects of the Invention) According to the present invention, since only the reconstructed image by the hologram formed on the cylindrical surface on the opposite side to the viewpoint is reflected by the concave mirror for observation, there is a gap between the mirror surface of the concave mirror and the focal point. Due to the principle that an object appears to be magnified, a distorted image that is stretched vertically is corrected by being stretched horizontally, and the hologram formed on the cylindrical surface on the viewpoint side is not illuminated by a white light source. , a reconstructed image can be obtained with a smaller number of unit holograms than in the past, and the reverse perspective phenomenon does not occur. In addition, in the present invention, it is not necessary to manipulate the original image as in the past, so it is easy to create a hologram film, and the reproduction device can be used simply by adding a shielding member and a concave mirror to the conventional reproduction device. There is an advantage in that the reproducing device of the invention is obtained. Furthermore, when an image of a car is reproduced using the device of the present invention, the reproduced image becomes a flat image with a larger perspective in the front, making it possible to express the beauty of the car's body shape. It can be said that the configuration according to the invention is suitable for a display.
