An endoscope apparatus includes a focus control section (347) that performs a focus control process that controls a position of a focus lens (220) to an in-focus position based on an in-focus evaluation value, the focus lens (220) being included in an optical system that forms an image of a captured image that is acquired by an imaging section (200), and the in-focus evaluation value being calculated from a first area within the captured image, and a change-in-scene detection section (346) that detects whether or not a change in scene has occurred from a second area that includes an area that differs from the first area, wherein the focus control section (347) is set to a standby state when the position of the focus lens (220) has been controlled to the in-focus position, and resumes the focus control process when a change in scene has been detected when the focus control section (347) is set to the standby state.
