Abstract
According to one embodiment, an image processing apparatus includes following units. The extraction unit extracts, from image data including a plurality of pixels, wavelength signal values of the plurality of pixels. The light attenuation amount calculation unit calculates a light attenuation amount based on a ratio of a wavelength signal value of a target pixel to a representative signal value obtained from wavelength signal values of a local region around the target pixel. The pigment amount calculation unit calculates a pigment amount of a predetermined pigment component at the target pixel by resolving the light attenuation amount using an absorbance base of the predetermined pigment component.
