  • Patent number: 7869654
    Abstract: 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.

  • Patent number: 7495633
    Abstract: 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.

  • Patent number: 7381443
    Abstract: The hard copy has a transparent coat layer which is formed on an image recording surface of a recording medium on a side of which an image is recorded and covers at least a part of the image recording surface. The transparent coat layer has asperities corresponding to three-dimensional information of the image, materials of objects forming the image, or density variation in the surface area of the image. The size, shape, spacing, height or other features of the asperities can be varied. The hard copy creation method records the image on the recording medium on the side of the image recording surface and then forms on the image recording surface the transparent coat layer having the asperities. The hard copy is created by first printing the image, and then forming on the image a transparent coat layer with the asperities.

  • Patent number: 7173743
    Abstract: An image reading apparatus and method are provided which precisely correct shading due to dispersion of the spectral sensitivity characteristic of a reading area of a reading device. Second correction values for correcting, for each of R, G and B, shading due to partial dispersion of spectral characteristics of color separation filters are respectively set and stored for each film type and for each of a plurality of blocks forming an image, on the basis of results of reading a film for correction value setting. Then, from the stored second correction values, correction values corresponding to a type of a film which is an object of reading are retrieved to derive correction values for each pixel by interpolation. The derived correction values for each pixel are added to first correction values for correcting shading due to irregularity in the amount of light or the like.

  • Patent number: 6999117
    Abstract: When using a digital still camera to sense and capture an image of a medium with a bar code being recorded thereon for indication of information to be input to the digital still camera (such as information indicative of photographing conditions and/or information representing processing conditions of image processing), judgment is done to determine whether a region equivalent to the bar code is present within an image, and then a region equivalent to the bar code is extracted for analyzation of coded information as indicated by such bar code; if no contradiction is found in the coded information then let it be stored in a storage or “memory” region pursuant to the kind of such coded information. And the information thus stored will be used to perform setting of image pickup conditions and/or setup of image processing condition.

  • Patent number: 6807294
    Abstract: In a digital still camera, it is determined whether a current photographing is performed in a document copy mode provided for precisely photographing a document or bar code, and if not, another determination is made as to whether the current photographing is performed under a particular image capturing condition including a resolution and a photographing distance. Further, if a determination that a paper money or security is photographed is affirmative, a predetermined image is overwritten on an image obtained by the photographing.
