ABSTRACT:
A document processing device automatically changes chart designs in inputted documents. The processing device receives simple indications showing the user's intentions, improves the quality of designs in accordance with input indications and outputs the improved design. A document image inputting module receives the current document. A chart extracting module then extracts areas of charts included in the inputted document. A chart area dividing module receives output from the extracting module and divides the extracted chart area into elements such as character, line and graphic areas. An element attribute providing module receives the divided elements and determines the positional relations of the elements with respect to the whole chart. An output image forming module receives information from both the chart area dividing module and the element attribute providing module. The output image is formed by coloring image data corresponding to each element. The image is then output to a visualizing medium to be discerned by the user.
