Abstract
(EN)
Provided are an image forming apparatus and an image forming method with which it is possible to more reasonably form an image on a cholesteric liquid crystal layer. In the image forming apparatus that forms an image in which a first region, a second region, and a third region each having a different color are arranged in a mesh is formed on a cholesteric liquid crystal layer, an exposure unit performs exposure on a liquid crystal composition, and an adjustment unit adjusts each ratio of the first region, the second region, and the third region in each part of an image. The first region is a region having a larger exposure amount during the exposure, the second region is a region having a smaller exposure amount during the exposure, and the third region is a region at a boundary position between the first region and the second region. Further, the adjustment unit adjusts, on the basis of a corresponding relationship between a parameter set to adjust the above ratio and a value changing with the parameter, the above ratio according to a setting color set for each part of the image.

L'invention concerne un appareil de formation d'image et un procédé de formation d'image qui rendent possible une formation plus raisonnable d'une image sur une couche de cristaux liquides cholestériques. Dans l'appareil de formation d'image qui forme une image, dans laquelle une première région, une deuxième région et une troisième région ayant chacune une couleur différente sont agencées en un maillage et qui est formée sur une couche de cristaux liquides cholestériques, une unité d'exposition réalise une exposition sur une composition de cristaux liquides, et une unité de réglage règle chaque rapport de la première région, de la deuxième région et de la troisième région dans chaque partie d'une image. La première région est une région ayant une amplitude d'exposition plus grande pendant l'exposition, la deuxième région est une région ayant une amplitude d'exposition plus petite pendant l'exposition, et la troisième région est une région au niveau d'une position frontière entre la première région et la deuxième région. De plus, l'unité de réglage règle, sur la base d'une relation correspondante entre un ensemble de paramètres pour ajuster le rapport ci-dessus et une valeur qui change avec le paramètre, le rapport ci-dessus conformément à un ensemble de couleurs de réglage pour chaque partie de l'image.

より合理的に画像をコレステリック液晶層に形成することが可能な画像形成装置及び画像形成方法を提供する。 互いに色が異なる第一領域、第二領域及び第三領域が網状に配置された画像を、コレステリック液晶層に形成する画像形成装置において、露光部が、液晶組成物に対して露光を行い、調整部により、画像の各部における第一領域、第二領域及び第三領域の各々の比率を調整する。第一領域は、露光時の露光量がより多い領域であり、第二領域は、露光時の露光量がより少ない領域であり、第三領域は、第一領域及び第二領域の境界位置にある領域である。また、調整部は、上記の比率を調整するために設定されるパラメータとパラメータに応じて変化する値との対応関係に基づき、画像の各部に対して設定された設定色に応じて上記の比率を調整する。
