    • 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 the kind of symbol information to be read. 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.
    • 一种用于读取能够改善解码精度的装置和方法,不受反射光束的反射系数波形的条件和要读取的符号信息的种类的影响。 该方法包括:从用光束照射的符号信息读取反射光束; 检测反射光束的反射系数波形中的峰值; 根据所检测的峰值中的高反射系数侧(白电平)的峰值计算第一峰值; 根据所检测的峰值中的低反射系数侧(黑电平)的峰值计算第二峰值; 以及基于所述第一峰值和所述第二峰值计算二值化阈值。
