摘要： Objects of the present invention are to facilitate filling out by hand an electronic paper and to realize digitization of contents with which the electronic paper is filled out by hand with a simple structure. A read image is obtained by optically reading a reading-object of the electronic paper. Based on the document information written on the electronic paper and writing-conditions during document writing, which are represented by the document information, a display image of the document in accordance with the read image information is formed. A written image is separated and extracted by converting a density only of pixels among the respective pixels of the read image, whose densities vary in accordance with the document writing and which correspond to a portion, to which ink of a pen for the handwriting is not adhered.

摘要： A holding stand is constituted by a carrying case for holding sheets of electronic paper and a base for uprightly supporting the carrying case that is substantially vertical. From the holding stand, two page fields, each expressing the number of pages of sheets of electronic paper to be displayed and position page field expressing a current page position of electronic paper and incremented on each of the sheets, are added to image data, and the image data is output to the sheets of electronic paper. In each sheets, when the two page fields coincide with each other in comparison between the two page fields, an image based on the image data is displayed in a display region. When the two page fields are different from each other, the position page field is incremented by one, and the position page field is transmitted to the next electronic paper.
