The first display value is compressed in accordance with preset compression characteristics, and outputted as a second display value expressed by a second number of gradations smaller than the first number of gradations. A recognition target is detected from an image expressed by compressed data that is a data string formed of the second display value. A ratio of the second number of gradations to the first number of gradations is taken as a basic compression ratio, a luminance range including at least a recognition target range that is a luminance range where the recognition target is estimated to be present is taken as a specified range, and the first display value corresponding to a boundary luminance value that is a minimum luminance value in the specified range is taken as a boundary first display value. In the recognition target range, the compression characteristics are set so that the second display value is a sum of a compressed value and the boundary first display value, the compressed value being obtained by compressing a value of not less than the boundary first display value among the first display values at a low compression ratio lower than the basic compression ratio."},"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","description":"In imaging processing, image data outputted from an imaging device is acquired as a data string formed of a first display value expressed by a first number of gradations obtained through conversion of","keywords":[]},"attribution":{"source":"Patentable","source_url":"https://patentable.app","canonical_url":"https://patentable.app/patents/US-9800881","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.
