The research aimed to reveal the reaction of humans to the differences in signal structures of some highly-natural visual information of high density and fractal structure by organically combining brain physiology, especially, non-invasive measurement of brain function, and psychological evaluation.To measure the influence of the density of the visual media information, we searched for and selected the targets of shooting that have rich fractal structures, and we developed the high-definition image samples for experimental presentation by means of still image, High-Vision video image, and 4K video image that had the information density four times of High-Vision. Sound samples were developed to synchronize with those still and video images. Physiological and the psychological evaluation methods were examined and developed suitably to evaluate the influences that such images and sounds exerted on human beings. We performed some examination to introduce up-to-date measurement techniques, such as fMRI, and the gene expression dynamics, to evaluate image media. The subjects' reactions to those samples (a still image, video images, and sounds that synchronized with those visual images) were examined all by the EEG and the biologically active substances in the blood, and the subjective impression evaluation.The experiment showed that alpha EEG, indicating the activation of the fundamental brain, was enhanced with statistically significance in the condition of High-Vision compared to that of NTSC, and in of 4K image to of High-Vision. Several indexes of the immunity revitalization and the density of the neurotransmitter in blood suggested the stress be decreased by higher density of image information. Additionally, we also underwent questionnaire of the paired comparison method of Sheffe, and found the effects that higher density of visual images improved the beauty and comforts of the images.

本研究旨在将脑生理学特别是脑功能的无创测量与心理学评价有机结合，揭示人类对一些高密度、分形结构的高度自然视觉信息的信号结构差异的反应，为测量视觉媒体信息密度的影响，寻找并筛选具有丰富分形结构的射击目标，通过静态图像、High-Vision视频图像和信息密度为High-Vision四倍的4K视频图像开发了用于实验演示的高清图像样本。声音样本的开发是为了与这些静态和视频图像同步。生理和心理评估方法进行了研究，并制定了适当的评估，这些图像和声音对人类的影响。我们进行了一些检查，介绍最新的测量技术，如功能磁共振成像，和基因表达动力学，以评估图像媒体。实验对象对这些样本的反应（静止图像、视频图像和与这些视觉图像同步的声音）都通过EEG和血液中的生物活性物质以及主观印象评估来检查。实验表明，与视觉障碍相比，在高视觉条件下，指示基本脑激活的α EEG增强，具有统计学显著性，从4K到High-Vision。免疫活性和血液中神经递质浓度等多项指标表明，高密度的图像信息可降低应激反应。此外，我们还进行了问卷调查的配对比较方法的谢夫，并发现，更高的视觉图像的密度提高了图像的美感和舒适度的影响。
