A processor and a memory store instructions that cause the processor to perform converting the two real space images into two frequency space images, each having a frequency including at least one frequency ingredient and an amplitude. A frequency space phase image is generated for each of the frequency space images by dividing each frequency ingredient by the amplitude of each respective frequency space image using a frequency. Frequency space correlation value information representing a correlation value for each frequency between the frequencies of the two frequency space phase images is calculated. The frequency space correlation value information is converted into real space correlation value information having a peak maximum value."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Depth information acquisition apparatus, imaging apparatus, depth information acquisition method and program","description":"A depth information acquisition apparatus acquires depth information of a subject by using two real space images, each having a different blur value, that are obtained by capturing a subject with diff","keywords":[]},"attribution":{"source":"Patentable","source_url":"https://patentable.app","canonical_url":"https://patentable.app/patents/US-9661302","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.
