Abstract
A reading device includes a carriage movable in a sub-scanning direction, an optical sensor mounted on the carriage, the optical sensor being configured to scan an object placed on a contact glass, a reference scale used as a reference when a dimension of the object is computed based on an image obtained as the optical sensor scans the object, a flat gauge to be scanned by the optical sensor to calculate a corrective value used to correct the image obtained by the optical sensor, and circuitry to calculate the corrective value based on a scanned image including the reference scale and the flat gauge obtained by the optical sensor, and correct, based on the corrective value, a measurement image including an image of the object and an image of the reference scale obtained by the optical sensor and compute the dimension of the object based on the corrected measurement image.
