    Abstract: An image reading apparatus includes a reading unit that reads a document transported in a second scan direction, a detector unit that detect a position of an edge of the document in a first scan direction crossing the second scan direction, a setting unit that sets a search range of the edge of the document in the first scan direction, the search range including the position of the edge detected by the detector unit, and a search unit that, on image data that the reading unit has read from the document, searches for the position of the edge within the search range of the edge set by the setting unit.

    Abstract: An image processing apparatus includes a processor configured to: extract a first target image corresponding to a reading target having a glossy portion and a non-glossy portion from a first read image acquired by optically reading the reading target in a first reading environment, and extract a second target image corresponding to the reading target from a second read image acquired by optically reading the reading target in a second reading environment in which specular light acquired from the reading target by an image sensor is of higher intensity compared to the first reading environment; execute an alignment of the first target image and the second target image if positions of the first and second target images do not coincide with each other and if the first and second target images are alignable by translating or rotating at least one of the first target image or the second target image; and form a composite image by executing a composition process that composites a non-glossy region corresponding to the non-glossy portion extracted from the first target image with a glossy region corresponding to the glossy portion extracted from the second target image.
