ABSTRACT:
A CPU36of a light emitting unit30fetches ith bit of transmission information TX stored in a transmission data memory33in synchronization with a clock signal CK from a timing generator35.The CUP36determines the bit value and fetches a first pattern sequence SA from a pattern data memory44when the bit is logic signal1,and fetches a second pattern sequence SB from a pattern data memory34when the bit is logic signal0,and outputs the first pattern sequence SA and second pattern sequence SB to a light emitting section37.While, a CPU39of a light receiving unit40extracts a pixel area with a time sequence luminance variation pattern from a frame image captured into a capture image buffer46,and binarizes the luminance variation pattern, and performs logic determination. A liquid crystal display44displays information of a light emitting area to be overlapped with a subject image.
