An image capturing apparatus comprising: a first light reception section that mainly receives light of a first wavelength region which is one of red light in the wavelength region 600-750 nm, green light in the wavelength region 490-600 nm and blue light in the wavelength region 420-490 nm; and a second light reception section that mainly receives light of a second wavelength region which is different from the first wavelength and is one of red light in the wavelength region 600-750 nm, green light in the wavelength region 490-600 nm and blue light light in the wavelength region 420-490 nm; a first light emission section; a second light emission section or a filter section; a light emission control section that causes successive emission of a) wideband light of a band that includes the first wavelength region and the second wavelength region by the first light emission section, and b) partial band light that is a narrowband light that includes a part of the first wavelength region and a part of the second wavelength region by the second light emission section or the filter section; an image capturing control section that captures a) an image of light received by the first light reception section when the wideband light has been emitted, b) an image of light received by the second light reception section when the wideband light has been emitted, c) an image of light received by the first light reception section when the partial band light has been emitted, and d) an image of light received by the second light reception section when the partial band light has been emitted; and an image generating section that generates, based on the images captured by the image capturing control section, a) an image of light within the first wavelength region other than the partial band light, and b) an image of light within the second wavelength region other than the partial band light; wherein the intensity of the image of light within the first wavelength region other than the partial band light is calculated by subtracting the intensity of the image of light received by the first light reception section when the partial band light has been emitted from the intensity of the image of light received by the first light reception section when the wideband light has been emitted, and the intensity of the image of light within the second wavelength region other than the partial band light is calculated by subtracting the intensity of the image of light received by the second light reception section when the partial band light has been emitted from the intensity of the image of light received by the second light reception section when the wideband light has been emitted. a first light reception section that mainly receives light of a first wavelength region which is one of red light in the wavelength region 600-750 nm, green light in the wavelength region 490-600 nm and blue light in the wavelength region 420-490 nm;
