An imaging apparatus includes an imaging circuitry, a signal processing circuitry, and a pixel interpolation processing circuitry. The apparatus calculates a degree of correlation for pairs in two orthogonal directions for an image signal obtained by the imaging circuitry including a single-chip image sensor having a four-color array filter using pixel data in an area around a target pixel, and performs pixel interpolation using the correlation degree as a determination criterion. When a color component pixel with a color identical to a color of a color component pixel subjected to pixel interpolation is not located in the direction having the high correlation, the pixel interpolation apparatus obtains a change ratio in a direction orthogonal to the direction having the high correlation by using a pixel value resulting from color space conversion in the direction orthogonal to the direction having the high correlation, and performs pixel interpolation processing based on the change ratio."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Pixel interpolation apparatus, imaging apparatus, pixel interpolation processing method, and integrated circuit","description":"Provided are a pixel interpolation apparatus, imaging apparatus, program, and integrated circuit that appropriately perform pixel interpolation on an image signal obtained by a single-chip image senso","keywords":[]},"attribution":{"source":"Patentable","source_url":"https://patentable.app","canonical_url":"https://patentable.app/patents/US-9787954","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.
