A document translation method having extracting a term from a document, executing a substitute process and outputting the term in a predetermined manner. The process of executing a substitute process on the term is performed in a translating process when the term from the document matches a term predetermined by a user. The substitute process is corresponding to the term and predetermined by the user.

Document translation method and document translation device

An image processing apparatus includes: a first memory that stores a first document file; a second memory that stores a second document file obtained by revising the first document file; an extraction unit that extracts a revised area of the second document file based on the first document file corresponding to the second document file and the second document file; and an extracted area specifying file generation unit that generates a file specifying the revision area extracted by the extraction unit.

A translation device has a translation processing unit that outputs character-area-character data by performing a translation process on the character-area-character data of an input image representing a figure-containing document, and outputting figure-area-character data by performing a translation process on the figure-area-character data of an input image representing a figure-containing document, a figure identification information searching unit that searches figure identification information used to identify a figure contained in a character area of the figure-containing-translation data, a linked page number searching unit that searches a page number in a character area of the figure-containing-translation data, a page number extracting unit that extracts a page number of a page included in figure area of figure identification information, and a page number rewriting unit that rewrites the searched page number linked to the figure identification information to the extracted page number of a page.

A document processing apparatus has a control section. The control section determines that at least some of a plurality of colors contained in input document data are a determined color group, determines at least one set of confusion colors of the colors contained in the determined color group based on confusion color information defined in association with color blindness of a human being in a predetermined color component space, and performs predetermined process for portions of the colors contained in the determined confusion color set, in the input document data.

Document processing apparatus

An apparatus for recognizing characters includes a text structure analyzing unit that analyzes an input image of text composed of mixed typed and handwritten characters and separates the input text image into predefined text imaging regions, a character clipping unit that clips characters one by one in each of the text imaging regions separated by the text structure analyzing unit, a feature vectors calculating unit that calculates feature vectors of the clipped characters for each of the text imaging regions, a feature vectors aggregating unit that aggregates the calculated feature vectors over a predefined range of the input text image, and a typed and handwritten character separation unit that separates characters involved in the input text image into the typed characters and the handwritten characters, based on a result of the aggregation by the feature vectors aggregating unit.

A Hough transform unit executes Hough transform to HIGH pixels of outline binary image data inputted thereto, and stores the calculation result in a Hough space data storage. A Hough space data calculating/projecting unit sequentially reads out data stored in the Hough space data storage, executes a specific calculation, and thereafter stores the calculation result sequentially in a calculated projection data storage. An angle detector sequentially reads out calculated frequency data stored in the calculated projection data storage, calculates the maximal value of the data read out, and detects an angle that gives the maximal value as the skew angle. The image processing device, being thus configured, allows detecting and correcting the skew angle with high accuracy, even when the input image contains image elements such as photograph images and dot images.
