Abstract
The subject of the present invention is to provide an apparatus which can improve decoding performance in the decoding processing of an encoded image pattern to reduce a load of the decoding processing. For solving the above problem, an apparatus according to the present invention is an apparatus for decoding an encoded image pattern having a detection pattern, the apparatus comprising a detecting unit configured to detect the detection pattern from an image, a correcting unit configured to correct a density of the encoded image pattern of which a position is specified by the detected detection pattern, based upon a density of the detected detection pattern, and a decoding unit configured to decode the encoded image pattern of which a density has been corrected.
