PROBLEM TO BE SOLVED: To simply add associated information without touching an object.

SOLUTION: A light indicator 1 generates light flux modulated based on the associated information acquired in response to the operation of a user and irradiates the light flux to an object 201 to form light spots 1a on the surface of the object 201. An imaging means (an imaging device 2 in the figure) images a light spots 1a on the surface of the object 201, a demodulating means (the imaging device 2 in the figure) demodulates the associated information based on a plurality of imaged pictures along the time series of the light spots 1a imaged by the imaging means.
