A method curving a second flat surface of the screen filter in a cylindrically curved surface shape of which the curvature is concentric in the longitudinal direction, uniform and gentle is combined with the screen filter made of the special prism lens.

Description

発明の詳細な説明Detailed Description of the Invention

本発明は、普通の写真やテレビ映像等の平面画像に使用することで立体視用眼鏡を使用することなく立体視を可能にするための特殊レンズ製画面フィルターに関するものである。The present invention relates to a special-lens screen filter for enabling stereoscopic viewing without using stereoscopic glasses by using it for planar images such as ordinary photographs and television images.

従来より透明プラスチック等の材料を用いて光分散型三角プリズムレンズの光を分散する両面または片面を局率が同心円の均一でゆるやかなシリンドリカル曲面状に加工するという方法による特殊なプリズムレンズの形状をした写真やテレビ等の立体視のための画面フィルターで、その写真やテレビ映像等と同等の大きさのこの特殊プリズムレンズ製画面フィルターを対象画像の手前にその画像と平行に配置することにより対象の平面画像を立体視することが可能な裸眼３Ｄの方法があった。Conventionally, a special prism lens shape is formed by processing a double-sided or single-sided light-dispersing triangular prism lens using a material such as transparent plastic into a uniform and gentle cylindrical curved surface with concentricity. This is a screen filter for stereoscopic viewing of a photograph or television, and this special prism lens screen filter of the same size as the photograph or television image is placed in front of the target image in parallel with the image. There has been a method of 3D with naked eyes that can stereoscopically view the planar image.

書籍名：裸眼３Ｄグラフィクス、出版社：朝倉書店、掲載箇所：第１９章、タイトル：ステレオレンズフィルタ方式、掲載ページ：１７１Ｐ〜１７６ＰBook name: naked eye 3D graphics, publisher: Asakura Shoten, publication location: Chapter 19, title: stereo lens filter system, publication page: 171P-176P

従来の特殊プリズムレンズ製画面フィルターにはそのレンズ形状の３Ｄ化特性である両眼視差を効果的に生じさせるということが不足しがちで、その結果十分な３Ｄ効果を得ることができない場合があるという欠点があった。本発明はこれらの欠点を除くためになされたものである。Conventional screen filters made of special prism lenses tend to be deficient in effectively generating binocular parallax, which is the 3D characteristic of the lens shape, and as a result, sufficient 3D effects may not be obtained. There was a drawback. The present invention has been made to eliminate these drawbacks.

従来の特殊プリズムレンズ製画面フィルターが両眼に視差を生じさせる方法としてそのレンズ形状の３Ｄ化特性のみを利用しているのに対して本発明は特殊プリズムレンズ製画面フィルターのレンズ形状により両眼に視差を生じさせるという３Ｄ化特性だけではなく片面を横方向に局率が同心円の均一でゆるやかなシリンドリカル曲面状に加工した特殊レンズ製画面フィルターにおいて、その画面フィルターのもう一方の平らな面を縦方向に局率が同心円の均一でゆるやかなシリンドリカル曲面状に湾曲させるという方法をその特殊プリズムレンズ製画面フィルターに組み合わせるという内容で構成されていて、この組み合わせにより左右の眼に生じる両眼視差だけではなく画面フィルター自体を湾曲させることにより両眼像差を際立たせることが可能となり、その結果、より効果的な立体臨場感を得ることができる。Whereas the conventional special prism lens screen filter uses only the 3D characteristics of the lens shape as a method of generating parallax in both eyes, the present invention uses both lens shapes of the special prism lens screen filter to In addition to the 3D characteristics of generating parallax, the other flat surface of the screen filter is a special lens screen filter that is processed into a uniform and gentle cylindrical curved surface with a concentricity in one side in the horizontal direction. It consists of the method of combining the screen filter made of the special prism lens with the method of curving in a uniform and gentle cylindrical curved surface with a concentric circle in the vertical direction, and only binocular parallax that occurs in the left and right eyes by this combination Instead of making the binocular image difference stand out by curving the screen filter itself Doo is possible, as a result, it is possible to obtain a more effective stereoscopic immersive.

本発明には特殊プリズムレンズ状に加工した画面フィルターのレンズ形状の特性だけでは不十分であった両眼視差を特殊レンズ製の画面フィルター自体を縦方向に湾曲させるという方法を組み合わせることで両眼視差だけではなく両眼像差も生じさせ、その結果、より効果的な立体臨場感を得ることができるという効果がある。The present invention combines binocular parallax, which has been insufficient with only the lens shape characteristics of a screen filter processed into a special prism lens shape, by combining the method of curving the special lens screen filter itself in the vertical direction. Not only the parallax but also the binocular image difference is generated, and as a result, a more effective stereoscopic presence can be obtained.

従来から立体視に利用されている光分散型三角プリズムレンズのうちの片面を横方向に局率が同心円の均一でゆるやかなシリンドリカル曲面状に加工した特殊レンズ製画面フィルターをフレネルレンズ化することにより薄型にして、そのフレネルレンズの平らな面を縦方向に局率が同心円の均一でゆるやかなシリンドリカル曲面状に湾曲させる。By creating a Fresnel lens screen filter made of a special lens, one of the light-dispersing triangular prism lenses that have been used for stereoscopic viewing has been processed into a uniform and gentle cylindrical curved surface with a concentricity in the horizontal direction. The flat surface of the Fresnel lens is curved in a longitudinal direction in a uniform and gentle cylindrical curved surface with a concentricity.

以下本発明の実施例について説明する。フレネルレンズ化した特殊プリズムレンズ製画面フィルターの平らな面を縦方向にシリンドリカル曲面状に湾曲させて液晶テレビなどの手前に配置することで裸眼３Ｄ画面フィルターとして利用できる。Examples of the present invention will be described below. It can be used as a naked-eye 3D screen filter by placing the flat surface of a special prism lens screen filter formed into a Fresnel lens into a cylindrical curved surface in the vertical direction and placing it in front of a liquid crystal television or the like.

本３Ｄ化フィルターはテレビなどの娯楽用映像の３Ｄ化に利用できるだけでなく、自動車運転シミュレータ画像や医用画像、天体観測画像の３Ｄ化などにも利用できる。This 3D filter can be used not only for 3D conversion of entertainment video such as television, but also for 3D conversion of driving simulator images, medical images, and astronomical observation images.
