Abstract
An image-reading apparatus includes a case constituted to shut off ambient light and including an opening on a bottom surface thereof, an image capturing unit capturing an image of a medium in the case through the opening, a plurality of light sources disposed in the case to emit light to the opening, and an image-processing unit performing image capturing by the image capturing unit, and performing composition process on plural image data captured by the image capturing unit. The light sources emit light in a direction to form shadowed areas outside of different edges of the medium when the medium is smaller than an area of the opening, and the image-processing unit extracts the edges based on the shadowed areas in the image data and crops the medium from the image data based on the extracted edges.
