Abstract:
1. An image capturing apparatus, comprising: a first light reception section that receives light of a first wavelength region; a second light reception section that receives light of a second wavelength region that is different from the first wavelength region; 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, and b) partial band light that mainly includes light of a part of the first wavelength region and a part of the second wavelength region; an image capturing control section that captures a) a first wideband image of light received by the first reception section when the wideband light has been emitted, b) a second wideband image of light received by the second light reception section when the wideband light has been emitted, c) a first narrowband image of light received by the first light reception section when the partial band light has been emitted and d) a second narrowband 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 a) the first wideband image of light received by the first light reception section, b) the second wideband image of light received by the second light reception section, c) the first narrowband image of light received by the first light reception section and d) the second narrowband image of light received by the second light reception section, i) a third narrowband image of light other than the partial band light within the first wavelength region, and ii) a fourth narrowband image of light other than the partial band light within the second wavelength region, wherein an intensity of the third narrowband image is calculated by subtracting an intensity of the first narrowband image from an intensity of the first wideband image, and an intensity of the fourth narrowband image is calculated by subtracting the intensity of an second narrowband image from an intensity of the second wideband image.
