Abstract: An image capturing device includes a processor. The processor is configured to implement: a switching control process for switching between a manual focus (MF) mode and an auto focus (AF) mode of performing auto focus control; a process for controlling driving of a focus lens; scene status determination process for performing a detection process for detecting a scene change during the MF mode and an estimation process for estimating distance change information indicating distance change between the image capturing section and an object. The processor is configured to implement: controlling the driving of the focus lens based on lens drive information; switching control for switching from the MF mode to the AF mode when the scene change is detected; and controlling the driving of the focus lens to bring the object into focus based on the distance change information.
