The controller further compares the compensated data with a first particular value. The controller executes the compensated data obtaining process with setting the light amount adjustment value to be a smaller value when the compensated data is greater than the first particular value, while with setting the light amount adjustment value to be a greater value when the compensated data is less than the first particular value. Further, the controller sets the light amount adjustment value to be a scan-time light amount adjustment value when the light amount adjustment value is equal to the first particular value. Then, the controller executes a scanning process according to the scan-time light amount adjustment value."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Image scanning apparatus","description":"In a scanning apparatus, a controller is configured to obtain black reference data, compensated data based on digital data (scan data) by scanning a reference member with the light source turned off, ","keywords":[]},"attribution":{"source":"Patentable","source_url":"https://patentable.app","canonical_url":"https://patentable.app/patents/US-9628667","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.
