摘要： PROBLEM TO BE SOLVED: To restrain deterioration of image contrast due to light other than the light for recording an image when applying light to a display medium to record the image. SOLUTION: In recording the image on electronic paper 200 using a recording apparatus 100 and a projector 300, the quantity of light of external light 420 applied to the electronic paper 200 is calculated from a change in impedance of the electronic paper 200. The frequency of recording voltage applied to the electronic paper 200 according to the calculated quantity of light is changed. Thus, even when the image is recorded by recording light 410 of the projector 300 with the external light 420 applied to the electronic paper 200, a change in reflectance due to the influence of the external light 420 is restrained, so that deterioration of contrast in the recorded image is suppressed.

摘要： PROBLEM TO BE SOLVED: To provide a technique which reduces blurring of an image caused by diffusion of recording light used for writing in an optical writing recording system.
SOLUTION: A photochromic compound is dispersed in a selective transmission layer 240. The photochromic compound has a characteristic in which there is almost no change in the transmissivity when the irradiated light amount is low, and as the irradiated light amount increases, there is a drastic change, and the transmissivity increases nonlinearly with respect to the irradiated light amount. Meanwhile, a luminous flux recording light radiated from a recording apparatus 10 is diffused before reaching the selective transmission layer 240 because it is transmitted through a plurality of layers. Since the selective transmission layer 240 has high transmittance for intense light in a center part out of recording light irradiated from a face 22b side and has low transmittance for weak light in a peripheral part out of the recording light, the light amount in the peripheral part is more reduced in an intensity profile within a spot diameter at the time of exit of recording light than in an intensity profile within a spot diameter at the time of incidence, and a diameter of a low-resistance spot on an optical address layer is reduced.

摘要翻译：要解决的问题：提供一种减少由光写入记录系统中用于写入的记录光的扩散引起的图像模糊的技术。光致变色化合物分散在选择性透射层240中。光致变色化合物具有当照射光量低时透射率几乎没有变化的特性，随着照射光量增加，是剧烈变化，并且透射率相对于照射光量非线性增加。同时，从记录装置10发出的光通量记录光在到达选择透射层240之前被扩散，因为它被透过多层。由于选择透射层240对于从面22b侧照射的记录光中的中心部分的强光具有高透射率，并且对于记录光中的周边部分中的弱光具有低透射率，所以周边部分中的光量在记录光退出时的光点直径内的强度分布比在入射时的光点直径内的强度分布中的强度分布更加减小，并且光学地址层上的低电阻光斑的直径减小。版权所有（C）2010，JPO＆INPIT
