项目摘要

This project is focused on the historical study of the Asian thoughts in Buddhist texts. It has aimed at the comparative study of cultures and thoughts of Asian peoples through making digital images of the extant Buddhist classic materials and editing texts critically.To make digital images of Tibetan Tripitaka Beijin Edition we have taken the way to photograph it with color films and to digitalize it by scanning. Kodacrome 25, 35 mm color film, was chosen by us in order to deal with the great number of materials. The film was proved to have enough resolution. It turned out that 6 pulse points at least are required to make a line width appear because the focusing point of the scanner was made large to remove noises. The resolution examination like this has never been done to digitalize images. Any expected results has not been attained in the case of employing OCR techniques even when the datas seem to be readable. This project has showed the way to certify the resolution by an easy examination. And also it has been showed that the digitalized information was not enough much in the case of 8 bits RGB in scanning. When the faded materials are digitalized in scanning, the significant informations are carried only by one or two bits of the lower among 8 bits so that they are included in the error. As the significant pulse data can be extended to 6 bits in the case of 12 bits, the error and the significant bit can be divided. And this project has showed that by photographing materials with a gray scale the scanner can be adjusted according to the gray scale in scanning so that we have a accurate line of luminosity and we can easily make a color adjustment by a numerical value.Moreover, using the digitalized images of Tibetan texts as the result stated above, we showed a part of the critically edited Tibetan text and the study of the Buddhist thought based upon it. Also we made a digital data of the Chinese Buddhist text (Tattvasiddhi), and published a study of it.

这个项目的重点是对佛教典籍中的亚洲思想进行历史研究。通过对现存佛教经典资料的数字化影像制作和文本的批判性编辑，对亚洲民族文化思想进行比较研究，对北京版《藏文大藏经》的数字化影像制作采取了彩色胶片拍摄和扫描数字化的方法。我们选择Kodacrome 25，35 mm彩色胶片，以处理大量的材料。这部电影被证明有足够的分辨率。结果表明，至少需要6个脉冲点来使线宽显现，因为扫描仪的聚焦点被做得很大以去除噪声。像这样的分辨率检查从未被用于数字化图像。在采用OCR技术的情况下，即使数据看起来是可读的，也没有达到任何预期的结果。这个项目已经展示了通过简单的检查来验证分辨率的方法。同时也表明，在8位RGB扫描的情况下，数字化信息量不够。在对褪色材料进行扫描数字化处理时，有效信息仅由8位中较低的1位或2位携带，从而包含在误差中。由于有效脉冲数据在12位的情况下可以扩展到6位，所以可以划分误差和有效位。本课题的研究表明，通过对具有灰度的材料进行拍摄，可以在扫描过程中根据灰度调整扫描仪，从而获得准确的亮度线，并可以方便地进行数值色彩调整。我们展示了一部分藏文校订本和基于此的佛教思想研究，并制作了汉传佛教文本的数字化数据，发表了汉传佛教文本的研究成果。
