Non-visible light communication system and signal processing device

Abstract

A non-visible light communication system and signal processing device are provided for processing the signal receiving side (i.e., the signal reading side) of optical communication, which can accurately collect information while suppressing the increase in processing load. The non-visible light communication system 100 includes: a transmission unit TT, which modulates and flashes a non-visible light wavelength band light EL (which is non-visible light) and transmits a signal; a light receiving unit RR, which receives a non-visible light wavelength band light EL; a first reading unit RU1, which reads a signal at a predetermined frame rate for a first range of an image obtained by receiving light at the light receiving unit RR; and a second reading unit RU2, which reads a signal at a higher frame rate than the first reading unit RU1 for a second range that is more limited than the first range.
