As the values, we decided to acquire the values of the specific pattern portion and the seaweed fabric portion.

Further, in the present invention according to claim 4, in the present invention according to claim 2, image data is obtained by changing the emission color of the light emitter.

In the present invention according to claim 5, in the present invention according to claim 1, a plurality of light emitters are provided, and image data is acquired by changing the light pattern created by the plurality of light emitters.
