An underwater sensor is configured to detect an underwater state in which at least part of an exterior of the electronic apparatus is located in the water and an above-water state in which the at least part of the exterior is not located in the water. An acceleration sensor is configured to detect acceleration. An image sensor includes a transparent member located in the exterior and is configured to receive light entering through the transparent member and generate a captured image. At least one processor is configured to identify a water surface image among a plurality of captured images generated by the image sensor, based on the acceleration and a transition timing at which one of the underwater state and the above-water state changes to the other state, the water surface image being captured when the transparent member reaches a water surface.
