Abstract

A screen filter for enabling stereoscopic viewing without using stereoscopic glasses by being used for a planar image such as a normal photograph or a television image. A filter portion of a screen filter of a photo, a television, a personal computer, or the like is processed into a uniform and gentle convex plate-like curved surface having a concentric curvature on one side of a light dispersion side of a light-dispersing triangular prism lens, The other side is formed into a special prism lens having a uniform and gentle concave plate-like curved surface with a concentric curvature, so that a planar image is stereoscopically viewed.

Description

The present invention relates to a screen filter for enabling stereoscopic viewing without using stereoscopic glasses by using it for a plane image such as a normal photograph or television image.

Most stereoscopic visions are established because parallax, which is an image shift caused by the right and left eyes viewing the object at different angles with respect to the object, occurs. However, even if a three-dimensional object is projected on a flat photograph or television image, no parallax is generated, so that it is only recognized as a flat surface. Conventionally, similar to the human eye, images taken from different angles with two cameras are combined, and then a three-dimensional image is created by creating parallax with red-blue glasses, polarized glasses, etc. A method of creating a solid by using parallax glasses for stereoscopic vision or using a prism sheet or lens sheet in which a large number of prisms and lenses are spread on a sheet to generate parallax. was there.

The conventional method has the following drawbacks.
(B) Many of the conventional methods required the use of glasses such as red / blue glasses, polarized glasses, and prism glasses for stereoscopic viewing.
(B) Since the prism sheet and lens sheet have many fine prisms and lenses spread over the sheet, the surface of the sheet is uneven, so the image is rough.
The present invention has been made to eliminate these drawbacks.

The present invention uses a transparent material such as glass or plastic to process one side of the light-dispersing triangular prism lens on the light-dispersing side into a uniform and gentle convex plate-like curved surface with a concentric curvature. A screen filter for photos and TVs made with a special prism lens with one side of the lens processed into a concave and concave concave curved surface with a concentric uniform curvature. This special size has the same size as the photos and TV images. The prism lens screen filter is arranged in parallel with the image in front of the target image to enable stereoscopic viewing of the planar image. In this screen filter, one side on the light-dispersing side is processed into a uniform and gentle convex plate-like curved surface with a concentric curvature, and the other side is processed into a uniform and gentle concave plate-like curved surface with a concentric curvature. It has a special prism lens shape, and not only disperses photos and television images with a prism lens, but also the convex plate-shaped curved surface and concave plate-shaped curved surface further disperse light left and right, thereby improving the spectral rate. As a result, a parallax occurs in the eyes of a person watching a photo or television, and stereoscopic vision is realized.

Since this prism lens screen filter has a flat plate-like solid surface with a smooth surface, the three-dimensional image is very smooth due to its unique shape, and a three-dimensional image can be seen even if the line of sight is changed. The biggest feature is that even if multiple people watch photos or TV images at the same time, all of them can view stereoscopic images without wearing glasses for stereoscopic viewing. Furthermore, by using this screen filter, it is possible to view normal 2D images as 3D images, so you can easily enjoy 3D images for games, CG animations, and movies.

The screen filter made of the special prism lens for stereoscopic vision is arranged in front of the target planar image so that the target image and the prism lens surface processed into a plate-like curved surface are parallel to each other. Moreover, since it is necessary to generate parallax to the left and right, the special prism lens needs to be disposed sideways. Since the present invention can be used for conventional planar image photographs, televisions, personal computers, etc., an existing personal computer screen fuller type removable screen filter is desirable.

Special prism for stereoscopic viewing, in which one side of the prism of the present invention is processed into a convex plate-like curved surface with a uniform and gentle concentric curvature, and the other side is processed into a concave and convex concave plate-shaped curved surface with a uniform concentric curvature It is a perspective view of a lens screen filter. It is a cross-sectional view of the central portion of the screen filter. It is explanatory drawing showing the use condition of this invention.
