Abstract: A document processing apparatus has an attachment unit and a storage. The attachment unit attaches a comment to an electronic document as additional information. The comment relates to a modification of the electronic document. The storage associates the comment with modified place information and stores them. The modified place information indicates a modified place of the electronic document, when the electronic document is modified based on the comment.

Abstract: An information storage unit stores pieces of information that are classified on the basis of their relationships. An information providing unit provides a client terminal with information stored in the information storage unit via a communication network in response to an access request from the client terminal. An access frequency acquiring unit acquires access frequencies, for respective classification items of the pieces of information, of accesses to the pieces of information. An information generating unit generates prescribed information so that pieces of information of plural classification items will be displayed in the client terminal in such a form as to be based on histories of the access frequencies.

Abstract: The invention provides an apparatus for reproducing the state in which an editor has added and described a comment to a document while what description content the editor is viewing so that the intention of the editor is rendered understandable. A document synthesis unit displays a layer on a screen, the document editing unit generates a new layer based on user operation to the document having the component layer displayed on the screen and adds it to the document, and generates at-add-time layer display state information of the layer displayed on the screen at the time of the addition.

Abstract: The invention provides a common document editing apparatus that is capable of reflecting the edition content based on a exclusive edition right on a common document even in the case where the exclusive edition right is cancelled forcibly. When an exclusive edition right of a common document stored in a document storing unit is requested, a lock information managing unit issues an exclusive edition right to permit exclusive edition and the lock information in stored in a lock information storing unit. Upon receiving the edition content together with the lock information, the lock information managing unit stores the edition content in the document storing unit only when the received lock information is identical with the lock information stored in the lock information storing unit. When the exclusive edition right is cancelled forcibly, the lock information managing unit 23 stores the lock information in an unlocked lock information storing unit.

Abstract: An image processing apparatus, which improves the qualitative effect or 3-dimensional effect on feeling of a subject picture, first analyzes the feature of the input picture thereby to evaluate feature values such as the mean value, histogram center value, variance, etc. pertaining to the lightness, saturation, and edge value. It discriminates the picture to be a texture stuff, colored stuff, etc. based on these feature values, and determines an image process operator and an image process parameter suitable for the purpose of process. It implements the image process that best matches with the picture based on the determined process operator and process parameter.

Abstract: An image processing coefficient determination method of an image processing system comprising the steps of:outputting test pattern image data having one or more image areas each containing a specific spatial frequency component by an image output device for preparing an output image,measuring a spatial frequency characteristic of the output image, anddetermining spatial frequency processing coefficients from a relationship between a spatial frequency characteristic of the test pattern image data and the measurement result of the spatial frequency characteristic of the output image.

Abstract: Three-dimensional LUTs produce a lightness signal L* from input color signals C, M and Y. The three-dimensional LUTs are respectively provided for four divisional sections of an input color signal K. A three-dimensional LUT switching device judges to what section a current value of the input color signal K belongs. A selector selects one of the LUTs in accordance with a judgment result. Similar processing is performed for chromaticity signals a* and b*. According to another aspect of the invention, three-dimensional LUT color converters produce color signals L.sub.2 *, a.sub.2 * and b.sub.2 * based on only input color signals C, M and Y. A position in the L*a*b* space of the color signals L.sub.2 *, a.sub.2 * and b.sub.2 * has a deviation from a position of color signals L.sub.1 *, a.sub.1 * and b.sub.1 * to be output actually. Based on an input color signal K, a one-dimensional LUT produces a lightness signal L.sub.3 *, which corresponds to the deviation.
