Information system and identification method

An identification method for causing a processor to execute a process, the method comprising executing on the processor the steps of:

• receiving a condition for acquiring spectral information specific to a target;
• determine whether the received condition includes selection of a first object of a plurality of objects, the target belonging in the first object, each of the plurality of objects having a plurality of pieces of spectral information;
• repeatedly selectively receiving a specific wavelength of light one wavelength at a time, the specific wavelength being selected from only a first wavelength range corresponding to the first object so as to capture a first plurality of images when the condition is determined to include the selection of the first object;
• identifying the spectral information of the captured first plurality of images;
• comparing the identified spectral information with the spectral information corresponding to the first object in a database and providing a comparison result, the database containing the plurality of pieces of the spectral information corresponding to the plurality of objects;
• and
• identifying the target based on the comparison result.

A non-transitory computer readable medium embodying computer readable instructions stored thereon for causing a computer to execute a process by a processor so as to perform the steps of:

• receiving a condition for acquiring spectral information specific to a target;
• determine whether the received condition includes selection of a first object of a plurality of objects, the target belonging in the first object, each of the plurality of objects having a plurality of pieces of spectral information;
• repeatedly selectively receiving a specific wavelength of light one wavelength at a time, the specific wavelength being selected from only a first wavelength range corresponding to the first object so as to capture a first plurality of images when the condition is determined to include the selection of the first object;
• identifying the spectral information of the captured first plurality of images;
• comparing the identified spectral information with the spectral information corresponding to the first object in a database and providing a comparison result, the database containing the plurality of pieces of the spectral information corresponding to the plurality of objects;
• and
• identifying the target based on the comparison result.
