Abstract
A CPUof a light emitting unitfetches ith bit of transmission information TX stored in a transmission data memoryin synchronization with a clock signal CK from a timing generatorThe CUPdetermines the bit value and fetches a first pattern sequence SA from a pattern data memorywhen the bit is logic signaland fetches a second pattern sequence SB from a pattern data memorywhen the bit is logic signaland outputs the first pattern sequence SA and second pattern sequence SB to a light emitting sectionWhile, a CPUof a light receiving unitextracts a pixel area with a time sequence luminance variation pattern from a frame image captured into a capture image bufferand binarizes the luminance variation pattern, and performs logic determination. A liquid crystal displaydisplays information of a light emitting area to be overlapped with a subject image.
