According to the imaging apparatus according to one aspect of the present invention, an image of high image quality can be acquired (reconstructed) in the imaging system configured to include the imaging apparatus by acquiring first and second projected images using Fresnel zone plates having different phases of local spatial frequencies. In addition, the design parameters (pitches and the areas of the Fresnel zone plates, the number of pixels of image sensors, a distance between the Fresnel zone plates and the image sensors, and the like) can be selected without considering an effect of a noise component, and the number of restrictions on the design parameters is small."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Image processing apparatus and image processing method that generate a complex image based on a Fresnel Zone pattern","description":"Provided an imaging system, an imaging apparatus and an image processing apparatus constituting the imaging system, an image processing method used in the image processing apparatus, and a non-transit","keywords":[]},"attribution":{"source":"Patentable","source_url":"https://patentable.app","canonical_url":"https://patentable.app/patents/US-11290642","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.
