Abstract
Achieved are both high speed in decoding a simple code and stability of decoding of a difficult code. A code image, generated by high-speed imaging control (first imaging control) for causing an imaging unit to generate the code image while causing an illumination unit to execute one type (N1=1) of illumination mode (a polarized illumination mode) among four types of illumination, is decoded by a core (high-speed decoding). On the other hand, a code image, generated by difficult-to-read imaging control (second imaging control) for causing the imaging unit to generate the code image while causing the illumination unit to execute all the four types (N2=4) of illumination modes among the four types of illumination modes, is decoded by a core (difficult-to-read decoding).
