Title:
IMAGE PROCESSING METHOD FOR OPTICAL INFORMATION READING DEVICE AND OPTICAL INFORMATION READING DEVICE
Document Type and Number:
WIPO Patent Application WO/2015/076297
Kind Code:
A1
Abstract:
To allow reading of even finely detailed information at high resolution regardless of the direction in which optical information is arranged in an image: multiple parallel quadrangle-shaped blocks are disposed in an image captured by an image capture means such that the optical information throughout the direction in which the optical information is arranged is covered by the multiple blocks (S4), each block being configured such that two respectively facing edges are parallel to an array direction of the pixels of the image and the other two edges are perpendicular to the direction in which the optical information is arranged; arrangement data which indicates the arrangement of the optical information within the blocks is generated from image data within each of the blocks (S6-S9); the generated arrangement data is coupled for the plurality of blocks (S11); and arrangement data which indicates the arrangement of the optical information overall is generated.
