An imaging apparatus includes: an imager that captures a subject image to generate image-capturing data; a memory that temporarily stores the image-capturing data; an image processor that performs image processing on the image-capturing data to generate image data; an interface detachably connected to an external non-volatile recording medium; and a controller that records the image data in the recording medium. The controller saves the image-capturing data from the memory by writing, in the recording medium, the image-capturing data as an incomplete file being a file format defined to manage, in the recording medium, the image-capturing data as a saving state where the image processing is not completed on the image-capturing data. The controller reads the saved image-capturing data from the recording medium into the memory, causes the image processor to perform the image processing, and records obtained image data by the image processing into the recording medium.
