a storage unit that stores image information on which additional information is to be overlaid;
a change unit that changes pixels, within a predetermined range of respective pixels constituting the image information, among
pixels constituting the additional information, to pixels having a different density or color tint from a density or color
tint of the image information and the additional information;
an overlay unit that overlays the additional information changed by the change unit on the image information held in the storage
unit; and
a determination unit that determines a processing method for changing the pixels constituting the additional information based
