An automatic exposure control device includes an image acquisition section that acquires an image that has been captured by an imaging optical system that receives reflected light, and includes an image of an object, the reflected light being light that has been applied to the object, and reflected by the object, an angle-of-view information acquisition section (310) that acquires angle-of-view information that indicates an angle of view of the imaging optical system when the image has been captured, and an automatic exposure control section (320) that performs an automatic exposure control process based on the acquired angle-of-view information.
