Abstract

The invention provides a light emitting device, a light emitting method, and a computer readable medium. The light emitting device includes: a light source; and a processor that performs control for causing the light source to flicker in a flicker pattern corresponding to output information including unique identification information of the light emitting device, the processor changing a time interval between the flicker patterns when causing the light source to flicker so as to repeat the flicker pattern.

Description

technical field [0001] The present disclosure relates to a light emitting device, a light emitting method, and a computer-readable medium. Background technique [0002] There is known a system that has: a light emitting device (also referred to as a tag) that is attached to an object such as a person or an object, and has a light source that blinks in a blinking pattern corresponding to output information including inherent identification information; and A camera, which is a device that captures light from the light sources of a plurality of light emitting devices, and the system recognizes each light emitting device (each object) based on the blinking patterns of the plurality of light emitting devices appearing in the captured image of the camera, and determines each object s position. This system is referred to below as a lighting device identification system. [0003] Japanese Patent Application Laid-Open No. 2006-153828 discloses a device in which an infrared generat...
