Title:
IMAGE PROCESSING DEVICE, IMAGE PROCESSING METHOD, AND RECORDING MEDIUM
Document Type and Number:
WIPO Patent Application WO/2022/180963
Kind Code:
A1
Abstract:
In the present invention, master image data is used to improve precision for correcting target image data. A generation unit (11) performs an affine transformation on the target image data, thereby generating a transformation image group including a plurality of transformation image data; a calculation unit (12) calculates a correlation value between transformation image data included in the transformation image group, and preregistered master image data; a selection unit (13) selects the transformation image data having the greatest correlation value from among the transformation image data included in the transformation image group; and a correction unit (14) corrects the selected transformation image data on the basis of the positional displacement between an object shown in the master image data and the object shown in the selected transformation image data.
