Instrument for measuring biological information and method for measuring biological information

An organism information measuring method, comprising:

• an illuminating step of illuminating an organism surface;
• a photoelectric conversion step of receiving light that has passed through a measuring region, out of light emitted in said illuminating step that has propagated through said organism and has again been emitted toward outside through said organism surface;
• a region changing step of changing a position and/or a shape of said measuring region;
• a computing step of acquiring light information related to said light received in said photoelectric conversion step and obtaining information related to said organism through reference to said light information and sample information;
• and
• a storing step of storing said sample information;
• wherein
• said sample information is defined by sample light information obtained in a sample photoelectric conversion step equivalent to said photoelectric conversion step when receiving light that has passed through a sample measuring region changed in a sample region changing step equivalent to said region changing step, out of light emitted from a sample light source equivalent to a light source used in said illuminating step toward a testee whose organism-related information is known which has propagated through said testee has been emitted again toward outside through a surface of said testee, and by said organism-related information of said testee.
