    • PROBLEM TO BE SOLVED: To maintain merging property in recorded motifs by using motif expression with gradations. SOLUTION: The method includes steps of: (S10) preparing two original images as data to be recording objects; (S20) disposing and defining a large number of unit areas having enough area to record interference fringes for visible light on a recording face of a hologram; (S30) superposing gradation patterns in which appearance probabilities of two record attributes are spatially gradually varied on the recording face and assigning one of the record attributes to each unit area according to the appearance probabilities of the respective record attributes at individual position; (S40) recording the first original image in a unit area where the first record attribute is assigned and recording the second original image in a unit area where the second record attribute is assigned, as an interference pattern, a grating pattern or a scattering structure pattern; and (S50) forming a recording pattern on a physical medium.

    • 要解决的问题:通过使用具有渐变的图案表达来保持记录图案中的合并性质。 解决方案:该方法包括以下步骤:(S10)准备两个原始图像作为要记录对象的数据; (S20)设置并限定具有足够面积的大量单位区域,以记录全息图的记录面上的可见光的干涉条纹; (S30)叠加两个记录属性的外观概率在记录面上在空间上逐渐变化的灰度图案,并根据各个记录属性在各个位置的出现概率向每个单位区域分配一个记录属性; (S40)将第一原始图像记录在分配有第一记录属性的单位区域中,并将第二原始图像记录在分配有第二记录属性的单位区域中作为干涉图案,光栅图案或散射结构图案 ; 和(S50)在物理介质上形成记录图案。 版权所有(C)2007,JPO&INPIT
