The correction unit includes an expected value calculation unit, a difference value calculation unit adapted to calculate a difference value between an expected value of a distribution of light amount and a measured value of a distribution of light amount when an image based on the image signal corrected by the correction unit is displayed in the display screen, and a correction amount calculation unit adapted to calculate a correction amount for the display problem region detected by the detection unit based on the difference value."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Image display apparatus, control method thereof, and computer-readable storage medium","description":"An image display apparatus having a display screen configured of a plurality of pixels includes a measurement unit adapted to measure a distribution of light amount when the display screen carries out","keywords":[]},"attribution":{"source":"Patentable","source_url":"https://patentable.app","canonical_url":"https://patentable.app/patents/US-8531444","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.
