1. An imaging apparatus, comprising: a light source device comprising a light source having a wavelength of a plurality of bands including visible light band and near-infrared band, the light source device being used to measure a shape of a subject as an object of a surgical operation; an imaging circuit configured to convert measurement light source light images of the plurality of bands from the light source device 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 laser controller for controlling an irradiation pattern of the visible light band and an irradiation pattern of the near-infrared band; a synchronizing circuit for counting an imaging timing synchronized with the imaging circuit; a calculation circuit 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 circuit; and a composition processing circuit configured to composition-process the shape of the surface and the shape of the inside measured by the calculation circuit to create one of two-dimensional image data and three-dimensional image data about the subject.
