Abstract

The present invention relates to a three-dimensional image system, which is a three-dimensional image system that can view a three-dimensional image without going through a lenticular screen as in the prior art. Conventional stereoscopic image information is recorded by the lenticular screen until the complete image is formed. That is, the image in which stereoscopic image information is formed before covering the lenticular screen cannot be regarded as clean image information such as a normal photograph by the information on which left and right stereoscopic images are recorded. However, the image recorded on the recording medium through the slit by the method according to the present invention looks like a normal picture, and it is possible to express three-dimensional texture without covering the lenticular screen. In order to obtain such an image, the image forming distance in the present invention meets the first constant distance at which the effect of the slits is eliminated when the distance between the slitting surface and the film surface starts from zero gradually increasing the image forming distance gradually. In the present invention, the distance is called an image forming distance.

Description

Stereoscopic Image System {SYSTEM OF 3-DIMENSIONAL IMAGE}

It is an object of the present invention to obtain an image that enables the expression of a texture that is much denser than a normal image without using a lenticular screen and to make a stereoscopic feeling. In addition to this, it is an object of the present invention to easily record a picture that can easily feel the texture even without a special effort for recording such an image.

Background Art There has been a conventional technique for representing a stereoscopic image by covering a lenticular screen and separating left information and right information from each other so that the brain recognizes it.

The present invention relates to a three-dimensional image system, which is a three-dimensional image system that can view a three-dimensional image without going through a lenticular screen as in the prior art. Conventional stereoscopic image information is recorded by the lenticular screen until the complete image is formed. That is, the image in which stereoscopic image information is formed before covering the lenticular screen cannot be regarded as clean image information such as a normal photograph by the information on which left and right stereoscopic images are recorded. However, the image recorded on the recording medium through the slit by the method according to the present invention looks like a normal picture, and it is possible to express a three-dimensional texture without covering the lenticular screen. In the conventional stereoscopic imaging technique using the slits, the light passing through the slits records the stereoscopic image information within a range where the light goes straight within the Fresnel region, so that the recorded stereoscopic image must be influenced by the slits. As a result, information patterns resulting from the characteristics of the slits are formed on the recorded image. However, the present invention does not use the light in the Fresnel region of the light passing through the slits, and is a technique of forming an image at a distance spaced apart from the Fresnel region by the distance between the slits and the film. In the present invention, the distance between the film surface on which the slits and the stereoscopic images are formed is the most important technology. When the distance between the slits and the film is defined as the image forming distance for recording the stereoscopic image, the image forming distance of the present invention is much longer than the image forming distance of the stereoscopic image technique using the ordinary slits. Since the image forming distance of the present invention is determined by the correlation between the transparent portion and the opaque portion in the slit, the distance cannot be uniformly limited. In the present invention, the method for calculating the glyphing distance may be defined as the glyphing distance in the present invention when a constant distance is met when the gross formation distance starts from zero and gradually increases the gross formation distance little by little. There is a number. The light passing through the slit travels straight in the Fresnel region without diffraction, and the light diffracts when it is out of the distance of the Fresnel region. The light passing through the slit forms a slit pattern due to the slit pattern on the film surface, starting from zero and passing the Fresnel region, and gradually increasing the distance between the film and the film. Information on the cotton gradually decreases due to the influence of the slit pattern. As the image forming distance is increased little by little, there is a distance where the images of the light passing through the slit do not exhibit any influence by the slit pattern. The above-mentioned constant image forming distance of the present invention refers to an image forming distance where the influence of the slits is removed for the first time, and the present invention is a technique for positioning a film and recording an image at this constant image forming distance. Hereinafter, the present invention will be described in detail with reference to the drawings.

1 is a configuration diagram of an image recording body. The present invention is not limited to photography as a stereoscopic image technique in all image recording media such as photographs, movies, and videos. Accordingly, although the camera which is the most basic of the imaging technology is shown in the drawings, it is representative of the general imaging system. All imaging systems have an optical system and a recording surface. In the present invention, the recording surface is represented as a film surface to simplify the description. A general imaging system is a configuration in which light representing a subject is recorded on the film 3 through the optical system 1 existing in the image recording body 2.

2 is a block diagram of a body image recording body using slits. Conventionally, there has been a technique of recording a stereoscopic image by placing the slits 4 in front of the film surface inside the camera in order to record the stereoscopic image information.

3 is a configuration diagram of a conventional vertical slits. Conventional slits (5) used for stereoscopic image recording through slits use vertical slits in which transparent portions and opaque portions are alternately formed vertically.

4 is a detailed view of FIG. In the vertical slit, the transparent portion 6 and the opaque portion 7 are alternately formed, and the gap between the transparent portion and the opaque portion is extremely small in the order of several microns. At this time, by controlling the ratio of the distance between the transparent portion and the opaque portion is of course to affect the formation of the stereoscopic image.

5 is a principle diagram of stereoscopic image recording using a conventional slit. Stereoscopic image information consisting of the right information 13 and the left information 12 is recorded on the film 9 through the slits 8 in which the transparent part 10 and the opaque part 11 are alternately formed. Become. At this time, the conventional technology is that the separation distance a between the slits and the film is in the Fresnel region within about 200 microns.

6 is an information configuration diagram of a conventional photograph in which a stereoscopic image is recorded. In the picture 14 in which stereoscopic image information is recorded, the right information 15 and the left information 16 are alternately formed, and an image in which such information is recorded looks different from a normal picture. In other words, the right image information and the left image information are shown as a mixture of pictures by the information column, so that the user cannot see a clear picture with the naked eye.

7 is a configuration diagram of a system for viewing a stereoscopic image. In FIG. 6, when the photograph on which the stereoscopic image information is recorded is overlaid on the lenticular lens 17, a clear image is formed, and the image is three-dimensionally recognized. That is, the left image information is recognized by the left eye, and the right image information is recognized by the right eye, so that the brain can perform a complex recognition function to feel stereoscopic images.

8 is a block diagram of the stereoscopic image recording system of the present invention. The stereoscopic image forming distance in the present invention is slightly longer than the distance between the conventional slits 18 and the film 19. Since the distance is determined by the ratio and size of the transparent portion and the opaque portion, the distance cannot be determined uniformly, but there is a unique image forming distance corresponding to each slit. As an embodiment of the present invention, the image forming distance of the present invention was 11 to 12 millimeters in the case of the slits having the size of the transparent portion of 30 microns and the size of the opaque portion of 180 microns. The reflected light passing through the slits of the above embodiment is the point where the pattern of the slits is almost alive at the above distance. The pattern of the slits is a distance that becomes thinner and lighter as the distance increases and starts to be almost invisible at the above distance. Even if the stereoscopic image according to the present invention does not cover the lenticular screen, it is possible to obtain an image having a prominent texture. In the conventional stereoscopic image, it is difficult to distinguish the image because the right information and the left information are intertwined before covering the lenticular. However, the image according to the present invention has the characteristic that the outstanding texture can be expressed while being able to enjoy the same level as a normal photograph.

9 is a configuration diagram of diagonal slits. Although the present invention can be expressed as a vertical slits, the direction formed by the slits formed by the diagonal lines of the patterns formed by the transparent portions and the opaque portions can be more completely eliminated.

10 is a configuration diagram of concentric slits. In addition to the slitting slits of FIG. 9, the application of the concentric slits, in which the transparent portion and the opaque portion alternately form concentric circles, also makes it easier to control the direction of the slits.

Even if the stereoscopic image according to the present invention does not cover the lenticular screen, it is possible to obtain an image having a prominent texture. In the conventional stereoscopic image, the right information and the left information are intertwined before the lenticular screen is covered to distinguish the image. Although it was difficult, the image according to the present invention has the characteristic that the outstanding texture can be expressed while being able to enjoy the same level as a normal photograph.
