本発明はカラー画像を表示するカラー画像表示方法に関
する。DETAILED DESCRIPTION OF THE INVENTION Technical Field The present invention relates to a color image display method for displaying a color image.
〈従来技術〉
従来の透過型のディスプレーフィルムは写真法又は印刷
法によって作られていた。写真法ではシアンＣ、マゼン
タＭ、イエロＹ、の３層の発色濃度を変化させてカラー
画像の各色彩を再現していた。<Prior Art> Conventional transmission-type display films have been made by photographic or printing methods. In the photographic method, each color of a color image is reproduced by changing the color density of three layers: cyan C, magenta M, and yellow Y.
又、印刷法ではＣ，Ｍ、Ｙとブラ・ンクにの網点面積の
変化とその部分的型なりでカラー画像の各色彩を再現し
ていた。In addition, in the printing method, each color of a color image was reproduced by changing the halftone dot area of C, M, Y, and blank and by changing its partial shape.
しかしながら両方式共に各色の色ずれが発生すると再現
色が希望した色と全く違ってしまう。即ち各色の重なり
具合が色彩の表現に大きな影響を与える欠点があった。However, in both methods, if a color shift occurs in each color, the reproduced color will be completely different from the desired color. That is, there is a drawback that the degree of overlapping of each color has a large effect on the color expression.
そこでＹ 、Ｍ、Ｃ及びＫの他にレッドＲ，グリーンＧ
、ブルーＢの染料又はインクを用いて、各色点が重なら
ないように配列することが提案されているが、各色点を
重なりなく配列することは非常に困難であった。しかも
、Ｒ，Ｇ。Therefore, in addition to Y, M, C, and K, red R, green G
Although it has been proposed to use blue B dye or ink to arrange the color points so that they do not overlap, it has been extremely difficult to arrange the color points so that they do not overlap. Moreover, R,G.
Ｂを加えたプリント方式では重なりが有ると色彩の誤差
を生む、すなわち、Ｒ，Ｇ、Ｈの染料又はインクが重な
ると減法混色の原理に基づき黒又はそれに近い暗色にな
り、重なり部分面積の増減は再現色の明るさ及び色度の
変化を招く。In the printing method that adds B, if there is any overlap, color errors will occur. In other words, if R, G, and H dyes or inks overlap, the color will become black or a dark color close to it based on the principle of subtractive color mixing, and the area of the overlapped portion will increase or decrease. This results in changes in the brightness and chromaticity of reproduced colors.
〈発明の目的〉
本発明は以上の如き従来技術の欠点に鑑み、色彩の変化
を無くすことが可能なカラー画像表示方法の提供を目的
としている。<Objective of the Invention> In view of the above-mentioned drawbacks of the prior art, an object of the present invention is to provide a color image display method that can eliminate color changes.
〈実施例〉 図は表示用透明フィルムの一部拡大図を示している。<Example> The figure shows a partially enlarged view of the transparent film for display.

The distance -o' corresponds to the synchronization of the aperture 4. Opening 4 is point A.

5). In this case, since the aperture 4 is surrounded by black grid lines, even if one color point is formed deviating from the aperture center O to some extent, that color point will not appear in the adjacent aperture. In other words, for the left and right movement of the color point, i-j in the figure
There is a margin of 1-m in the figure until a white spot occurs in the 45'' direction with respect to the grid line 2.

It is desirable that a black checkered pattern be printed first on the paper (paper). When fluorescent dyes or ink-based fluorescent colorants are used, the overlapping order of the grid pattern and color dots changes depending on whether the short wavelength (ultraviolet) illumination of the fluorescent reservoir is illuminated from the front or the back. obtain.
