Abstract: In a case where a position of a recognized cell is shifted from a position of a ruled line of an actual cell, if the recognized cell is deleted, a part of the ruled line of the actual cell is deleted. According to an aspect of the present invention, straight lines are detected from regions around four sides constituting the recognized cell, and an inside of a region surrounded by the detected straight lines is deleted.

An image processing apparatus including a specifying unit configured to specify a character within an image, a setting unit configured to set a representative color to the specified character by using colors of pixels constituting the specified character, a determination unit configured to determine whether the specified character is a reversed character, and a correction unit configured to correct the set representative color in the case where the specified character is determined to be a reversed character.

Abstract: An image processing apparatus includes a character recognition unit configured to perform character recognition of a character region where characters exist in an image to generate character code, a detection unit configured to detect a region of the image where a feature change in the image is small, and a placement unit configured to place data obtained from the character code in the detected region.

Abstract: There is provided an information processing apparatus. When an information processing apparatus receives a selection of a position under a situation where an image including a plurality of recognized cells is displayed on a display unit, the information processing apparatus displays an editing region for allowing a user to edit a text included in a recognized cell including the position, and a handle for changing the position of the recognized cell including the position which has been received a selection.

Abstract: Character code data and vector drawing data are both listed and provided in a re-editable manner. Electronic data is generated in which information obtained by vectorizing character areas in an image and information obtained by recognizing characters in the image are stored in respective storage locations. As for the electronic data generated in this manner, because character code data and vector drawing data generated from the input image are both presented by a display and edit program, a user can immediately utilize the both data.

Abstract: Image data is divided into blocks and a histogram of a color appearing in a target block is formed. A target color region is decided as significant, if the area of that region is larger than a threshold, or if that area is smaller than the threshold and if that region is located at a boundary of the target block and attribute information for the pixel at the boundary in that region indicates a preset attribute. If that region is not decided as significant, to integrate that region to a region of another color which contacts that region, the color of the pixel in that region is substituted by the other color. If that region is decided as significant and if the chrominance difference between that region and the region decided as significant in another block which contacts the target block is smaller than another threshold, these regions are integrated.
