Imaging apparatus and imaging method

An imaging apparatus, comprising:

• a light source section comprising a light source having a wavelength of a plurality of bands, the light source section being used to measure a shape of a subject as an object of a surgical operation;
• an imaging section configured to convert measurement light source light images of the plurality of bands from the light source section into a plurality of electrical measurement imaging signals, the measurement light source light images being reflected from a surface and an inside of the subject;
• a calculation section configured to measure a shape of the surface and a shape of the inside in the subject based on the plurality of electrical measurement imaging signals obtained through the conversion in the imaging section;
• and
• a composition processing section configured to composition-process the shape of the surface and the shape of the inside measured by the calculation section to create one of two-dimensional image data and three-dimensional image data about the subject.
