Abstract: An endoscope system includes a processor configured to generate a clock at predetermined timing, a light source apparatus configured to irradiate white light and excitation light in a time division manner in synchronization with the clock, and an endoscope configured to perform image pickup based on irradiation timing of the light source apparatus. The processor generates a first white light image at a first clock, generates a first fluorescent image at a second clock, generates a second white light image at a third clock, and generates a third white light image at a fourth clock and superimposes the second white light image and the first fluorescent image at the fourth clock and superimposes the third white light image and the first fluorescent image at a fifth clock.

Abstract: An endoscope system is provided with: a processor; a light source; and an image pickup device. The processor performs control for causing reflected light images corresponding to a predetermined period before start of the fluorescence occurrence period during the fluorescence non-occurrence period, among the reflected light images, to be recorded to the first storage medium; and, furthermore, performs control for causing the reflected light images to be recorded to the first storage medium during an after-end-of-fluorescence-occurrence period corresponding to a predetermined period with an end of the fluorescence occurrence period as a start point, and performs control for causing the reflected light images not to be recorded to the first storage medium during the fluorescence non-occurrence period after an end of the after-end-of-fluorescence-occurrence period.
