An imaging apparatus performs search processing for shooting frame images while moving the focus lens and obtaining a frame image which is focused on each AF area, performs moving image shooting processing for recording a moving image while moving the focus lens after ending the search processing, and performs still image generation processing for generating a still image from among a plurality of frame images composing the recorded moving image data, by referring to a result of the search processing after the moving image shooting processing. When a user performs an operation of changing a focus position on a subject during a period from an end of the search processing to an end of the moving-image shooting processing, the imaging apparatus displays a message that calls user's attention on the display unit.
