Subsequently, the number of chromatic pixels of one line is counted to output it to a memory, and when it is summed up to an end line of the available image area, a difference between a count number N1 in one previous line of the available image area and a count number N2 in the end line of the available image area is calculated to thereby compare the difference with a predetermined threshold value. When the difference is larger than the threshold, it is determined to be a chromatic image, whereas when the difference is smaller than the threshold, it is determined to be an achromatic image."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Image processing method, image processing apparatus, image forming apparatus, and recording medium","description":"An available image area is recognized from information, including a read start position and a read end position of a document, a scaling for performing image processing, a processing object position, ","keywords":[]},"attribution":{"source":"Patentable","source_url":"https://patentable.app","canonical_url":"https://patentable.app/patents/US-8508823","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.
