An endoscope device is disclosed which includes an image processing unit that generates a first image corresponding to light in a green wavelength band on the basis of an imaging signal generated by an imaging device when a light source unit emits first illumination light or second illumination light, and generates a second image corresponding to light in other one of wavelength bands. Resolution of the first image obtained when the light source unit emits the first illumination light is equal to or higher than resolution of the first image obtained when the light source unit emits the second illumination light, and resolution of the second image obtained when the light source unit emits the second illumination light is higher than resolution of the second image obtained when the light source unit emits the first illumination light.
