Abstract
Provided are an imaging apparatus and an imaging method that make it possible to apply light having an optimum wavelength to capture an image without a user taking heed of a type of an imaging object. A wavelength of light optimum for analysis of a target is specified as an effective wavelength from a multispectral image of the target on which white light is applied, and light of the effective wavelength is applied upon the target. The target in this state is captured as a multispectral image, and the target is analyzed on a basis of a spectral image of an effective wavelength.
