A second multiplier multiplies the adjusted correction value by a cosine of an angle formed between a position of each target pixel and the center of the frame and generates a horizontal correction value that corrects the target pixel in a horizontal direction. A horizontal filter adds all multiplication results obtained by multiplying a plurality of pixels in a left-right direction with each target pixel as a center, by left-right asymmetric coefficients, generates a horizontal high-pass filter component, adds, to each target pixel, a horizontal correction component obtained by multiplying the horizontal high-pass filter component by the horizontal correction value, and corrects each target pixel in the horizontal direction."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Image processing device and image processing method capable of correcting distortion occurred in an image captured through a zoom lens","description":"A first multiplier multiplies a correction value by an adjustment coefficient and generates an adjusted correction value, the correction value being read from the correction value table, and the adjus","keywords":[]},"attribution":{"source":"Patentable","source_url":"https://patentable.app","canonical_url":"https://patentable.app/patents/US-11991443","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.
