  • Patent number: 10085630
    Abstract: An endoscope apparatus includes: first and second cooling units configured to cool first and second light source portions; an image pickup portion configured to generate a picked-up image; and a cooling control portion configured to control amounts of light emission of the light source portions while maintaining an amount-of-light ratio so that the brightness of the picked-up image becomes the target brightness and control cooling based on the information about the amount-of-light ratio and the brightness control information; wherein the cooling control portion decides a cooling capacity of the first cooling units and a cooling capacity of the second cooling units for cooling the respective light source portions for which the amounts of light emission are controlled, at the cooling ratio, so as to cause the light source portions to be included within a predetermined temperature range, based on the brightness control information.
