IMAGE PROCESSING APPARATUS, IDENTIFICATION APPARATUS, METHOD FOR DETERMINING BIT SEQUENCE AND COMPUTER READABLE MEDIUM

An image processing apparatus includes: an image acquisition unit that acquires an image read from a medium having the image printed thereon, the image representing a specific bit sequence; an information acquisition unit that acquires a state information piece indicating a reading state of the image acquired by the image acquisition unit; a detection unit that detects a bit sequence from the image acquired by the image acquisition unit; and a determination unit that determines the specific bit sequence on the basis of the bit sequence detected by the detection unit and the state information piece acquired by the information acquisition unit.
