The control circuit turns on and off the sample hold signal, based on each of input fed to the drive circuit and the signal processing circuit."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Image scanner, image forming apparatus, and sample hold control method","description":"A scanner includes: a photoelectric conversion element configured to photoelectrically convert light reflected from an original image to form an image signal; a timing generation circuit configured to","keywords":[]},"attribution":{"source":"Patentable","source_url":"https://patentable.app","canonical_url":"https://patentable.app/patents/US-8472091","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.
