Each of the detection image parts includes a plurality of regions with respective luminance values different from each other, and the background images have luminance values lower than the luminance values of the detection image parts. The detection image generation section changes at least one of a luminance distribution of each of the detection image parts of the detection image to be generated and a size of each of the background images so that a luminance distribution of each of the detection image parts of the taken detection image obtained by imaging is approximated to a luminance distribution of corresponding one of the detection image parts of the detection image."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Image processing device, projector, and method of controlling projector","description":"A detection image generation section generates a detection image, which is an image for detection a state of a projection image, and includes a plurality of detection image parts, and background image","keywords":[]},"attribution":{"source":"Patentable","source_url":"https://patentable.app","canonical_url":"https://patentable.app/patents/US-9762869","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.
