And the image reading device calculates as a width for size detection a width from a reference line to the target line, sets as the size of a document a reference size that has a width closest to the width for size detection, performs image processing on the output image data based on the reference size set as the size of the document, and outputs the processed image data."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Image reading device and image forming apparatus","description":"An image reading device generates, as image data of a reading region, image data for output and image data for size detection, the latter having a lower resolution than the former, discriminates high ","keywords":[]},"attribution":{"source":"Patentable","source_url":"https://patentable.app","canonical_url":"https://patentable.app/patents/US-9641712","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.
