Abstract: An endoscope apparatus includes an objective optical system that is configured so that an observation magnification in at least a center part of an observation range is variable, a magnification control section that controls the observation magnification, and a brightness control section that performs a photometric process that attaches weight to a center part of an image that corresponds to the center part of the observation range when the observation magnification is a second magnification that is higher than a first magnification as compared with a case where the observation magnification is the first magnification, and adjusts the brightness of the image based on the result of the photometric process.
