IMAGE OBTAINING METHOD AND IMAGE CAPTURING APPARATUS

摘要

PROBLEM TO BE SOLVED: To provide an image obtaining method and image capturing apparatus capable of obtaining a deep portion image that allows only an image of blood vessel located in a deep layer of an observation area to be observed appropriately. SOLUTION: The image obtaining method includes the steps of: obtaining a first image captured by directing light having a first wavelength to the observation area and receiving light emitted from the observation area, and a second image captured by directing light having a second wavelength shorter than the first wavelength to the observation area and receiving light emitted from the observation area; and obtaining the deep portion image of the observation area by subtracting the second image from the first image.
