A second sum is calculated which is a sum, at a position of the target pixel, of each of light intensities of dispersed lights generated when each of pixel lights by pixels around the target pixel pass through the optical system. A second light intensity of the pixel light by the target pixel is calculated by subtracting the second sum from the first light intensity."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Image processing device, image processing method, and projection apparatus","description":"A first sum is calculated which is a sum of light intensities of dispersed lights generated when a pixel light by a target pixel passes through an optical system, and a first light intensity is calcul","keywords":[]},"attribution":{"source":"Patentable","source_url":"https://patentable.app","canonical_url":"https://patentable.app/patents/US-9686521","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.
