An object image and search region image storage unit stores an image of the object and images of at least two sub blocks from the object. A search region setting unit sets a size of the sub blocks. A region of interest (ROI) generation unit sets a weight and a characteristic value of the sub block. A bar code symbology identification unit searches vertically a bar code region from the ROI and generates a bar code edge region. An information interpretation unit interprets object information corresponding to the bar code edge region. A result process and storage unit processes and stores the interpreted object information.
