Abstract: A document-information processing device includes an analysis unit and a process unit. The analysis unit analyzes construction of document information that is composed of a plurality of elements, and evaluates a degree of significance of each element included in the document information. The process unit selects an element sequentially from the plurality of elements, starting from an element whose degree of significance is the highest and ending with an element whose degree of significance is the lowest, and places a selected element on an output document. Alternatively, the process unit reduces an information content of the document information by eliminating or compressing an element whose degree of significance is low.

Abstract: A storage location and a name of a document designated by a user are displayed on a main window screen. A viewing history management section determines if the information in display has been viewed before by referring to a content of a document management information storage section, acquires an ID number corresponding to the information if viewed before, and, if not, issues a new ID and registers it in the storage section. A list of a related document group is created by analyzing viewing history information accumulated daily, determining a document group related to a document in view, and creating the group as a list.

Abstract: In a document management apparatus and related document extracting method of the present invention, an operational history record of one of stored documents is generated every time an operation on the one of the stored documents is performed by a document operation device. The generated operational history records are stored. It is determined whether a selected item of the operational history record, stored for a currently processed document among the stored documents of the group, matches with a corresponding item of each of the operational history records, stored for the remaining ones of the stored documents other than the currently processed document, so that a list of related documents, which are related to the currently processed document, is extracted from the remaining ones of the stored documents, based on results of the matching.

Abstract: In order to achieve consistently accurate results in gamut mapping, a first device gamut is systematically mapped into a second device gamut by using a predetermined set of mapping techniques, and based upon a predetermined index of the generated output color quality, the best mapping technique is selected. In the alternative, the best mapping technique is subjectively selected by an operator.

Abstract: An image processing device forming a reproduced image from a plurality of color recording signals, each of which is generated at a corresponding one of scans on an original image and derived from color digital signals obtained at the corresponding one of the scans, includes a threshold-value generation unit generating a threshold value based on the color digital signals at a first one of the scans, and a background removal unit reducing background noise in the reproduced image by using the threshold value at second and following ones of the scans.
