The incorrect recognition index calculator calculates incorrect recognition indexes. The incorrect recognition index is set based on a count of incorrect recognition characters. The count of incorrect recognition characters is a count of candidates for characters possibly incorrectly recognized when the documents are read. The incorrect recognition index is set such that recognition certainty indicative of accuracy of the recognition becomes smaller as the count of incorrect recognition characters increases. The certainty calculator adjusts the recognition certainty using the incorrect recognition index. The direction determining unit that determines a direction of the documents based on the adjusted recognition certainty. The image processing unit corrects the image data based on the determined document direction to align image directions of the plurality of documents."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Image reading apparatus that aligns directions of document images, image reading method, image forming apparatus, and recording medium","description":"An image reading apparatus includes a character recognition processing unit, an incorrect recognition index calculator, a certainty calculator, a direction determining unit, and an image processing un","keywords":[]},"attribution":{"source":"Patentable","source_url":"https://patentable.app","canonical_url":"https://patentable.app/patents/US-10482338","license":"CC-BY-4.0-like","license_terms":"AI-generated analysis on this page (summary, layman_explanation, technical_analysis, business_analysis, faqs) may be reused with attribution and a visible link back to the canonical URL above.
