Abstract

A reading device (1, 10, 25) and a method of correction. The reading device (1, 10, 25) includes a scanner (31) configured to read an image in a first wavelength range and an image in a second wavelength range from light reflected by a surface of a recording medium, a detector (32, 33) configured to detect a change from a reference position in a reading-depth direction when the surface (100a) of the recording medium is read by the scanner (31), based on an amount of characteristic read from the image in the second wavelength range, and a corrector (34) configured to correct the image in the first wavelength range based on the change detected by the detector (32, 33). The method includes reading the images in the first wavelength range and the second wavelength range from the light reflected by the surface (100a) of the recording medium.
