IMAGE PROCESSING APPARATUS

摘要

An image processing apparatus, includes: an acceptance unit that accepts image data and reading data read from a medium; an extraction unit that extracts a rectangular image by segmenting one image of the image data and the reading data to have a size calculated based on an error; a searching unit that searches for a matching position of a rectangular image in the other image of the image data and the reading data, which corresponds to a position of the rectangular image extracted by the extraction unit within a range of a movement amount calculated based on the size of the rectangular image extracted by the extraction unit and a predetermined size calculated by the error; and a comparison unit that compares the rectangular image extracted by the extraction unit with the rectangular image in the other image at the position searched by the searching unit.

主权项

1. An image processing apparatus, comprising:
an acceptance unit that accepts image data and reading data read from a medium on which an image of the image data is formed; an extraction unit that extracts a rectangular image by segmenting one image of the image data and the reading data to have a size calculated based on an error which occurs from an image forming apparatus forming the image of the image data on the medium and/or an image reading apparatus reading the medium; a searching unit that searches for a matching position of a rectangular image in the other image of the image data and the reading data, which corresponds to a position of the rectangular image extracted by the extraction unit within a range of a movement amount calculated based on the size of the rectangular image extracted by the extraction unit and a predetermined size calculated by the error; and a comparison unit that compares the rectangular image extracted by the extraction unit with the rectangular image in the other image at the position searched by the searching unit.
