PROBLEM TO BE SOLVED: To provide a device for automatically, accurately calculating and correcting the inclination of an image at high speed by installing a mask pattern having inclination and calculating the correlation between an image for inclination inspection and the mask pattern, to be efficiently used in an inspection device for various images, such as an inspection device for an OCR or a printing matter. SOLUTION: In order to solve problems that an image having no register frequently appears in an inspection object image to make automatic inspection impossible and a means for automatically judging inclination has not yet reached to a practical level from the standpoint of processing speed and accuracy, the mask pattern having inclination is installed and a means calculating a frequency at which the image is present on the mask pattern and judging that the inclination of the mask pattern in the smallest frequency is the same as the inclination of the image is installed. |
