To provide image information for exactly confirming and grasping shapes and states of a surface and an inside of a subject as an object of a surgical operation, an imaging apparatus includes: a light source section (2, 40) including a light source having a wavelength of a plurality of bands； an imaging section (15) 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 (13, 16, 19) 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 (19) configured to composition-process the shape of the surface and the shape of the inside measured by the calculation section to create two-dimensional image data or three-dimensional image data about the subject.
