1. An imaging apparatus comprising: an image generation section that generates at least one of a first captured image having a predetermined size and a second captured image having an aspect ratio different from that of the first captured image; a recording control section that, when an instruction operation to record the generated captured image is received, records the generated captured image based on the instruction operation; and a display control section that, when a captured image to be displayed at the time of displaying the recorded captured image on a display section is the second captured image, displays the second captured image and an enlarged image of a specific region in the second captured image on the display section in a correlated manner, wherein the display control section displays the captured image, which is recorded by a recording process after the recording control section finishes an operation of recording captured images, on the display section as the captured image to be displayed, wherein when the captured image to be displayed is the first captured image, and a predetermined operation is received after the first captured image is displayed on the display section, the display control section displays the first captured image and an enlarged image of a specific region in the first captured image on the display section in a correlated manner, wherein the display control section sets a magnification ratio of the enlarged image of the specific region in the second captured image displayed on the display section when the captured image to be displayed is the second captured image, so as to be larger than a magnification ratio of the enlarged image of the specific region in the first captured image displayed on the display section when the captured image to be displayed is the first captured image.
