The method includes: reading a reflected light beam from symbol information irradiated with a light beam; detecting peak values in a reflection coefficient waveform of the reflected light beam; calculating a first peak value according to a peak value at a high reflection coefficient side (white level) among the peak values detected; calculating a second peak value according to a peak value at a low reflection coefficient side (black level) among the peak values detected; and calculating a binarization threshold based on the first peak value and the second peak value."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Apparatus and method for reading symbol information","description":"An apparatus and method for reading symbol information enabling improvement of decoding accuracy, not being affected by the condition of a reflection coefficient waveform of a reflected light beam and","keywords":[]},"attribution":{"source":"Patentable","source_url":"https://patentable.app","canonical_url":"https://patentable.app/patents/US-8485444","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.
