Abstract
There is provided a device for reading a code on a subject. The device includes an imaging unit provided with an imaging element, a depth-of-field extending unit, and an optical distorting unit. The imaging unit captures an optical image formed on a light-receiving surface of the subject. The depth-of-field extending unit acquires a focused image regardless of distance to the subject, within a predetermined read-out range. In the optical distorting unit, the captured optical image is distorted such that i) the focused image at a minimum distance in the read-out range includes an overall image of the code and ii) the focused image at a maximum distance in the read-out range is provided so as to allow at least a predetermined number of pixels to be assigned to a unit image of the code.
