Abstract:
1. An image capturing apparatus comprising: a light emitting section that emits light to a subject; a light receiving section that receives light in a first wavelength region, light in a second wavelength region, and light in a third wavelength region from the subject, the second wavelength region being different from the first wavelength region; a reflectance calculating processing unit configured to calculate a first reflectance of light in the first wavelength region from the subject and a second reflectance of light in the second wavelength region from the subject, based on the light emitted by the light emitting section and the light received by the light receiving section; a depth identifying processing unit configured to calculate a depth, from a surface of the subject, of an object inside the subject that is included in an image resulting from the light received by the light receiving section, based on the first reflectance and the second reflectance; a movement identifying processing unit configured to identify movement of the subject, the movement identifying processing unit determining which wavelength region of the first, second and third wavelength regions is used to identify the movement of the subject in each image region based on a contrast of a captured image taken with at least one of the first, second and third wavelength regions, wherein the reflectance calculating processing unit calculates the first reflectance and the second reflectance from the light in the first wavelength region and the light in the second wavelength region, respectively, for which a positional shift caused by the movement of the subject is corrected using the movement identified by the movement identifying processing unit based on the light in the wavelength region determined by the movement identifying processing unit to provide a movement-corrected image signal; and a display configured to display a corrected image based on the movement-corrected image signal.
