See full text

A reflected light amount from a patch under a first light source is acquired, and a reflected light amount from the patch under a second light source whose wavelength band is different from the first light source is acquired. The type of a printing medium on which the patch is printed is determined based on the ratio of the two acquired reflected light amounts.
