The present disclosure aims to achieve a more effective image in slow motion. An imaging apparatus of the present disclosure includes an image sensor that outputs image data at a first frame rate and an image processor. The image processor: (i) generates motion image data having a second frame rate that is 1/N of the first frame rate, based on the image data having the first frame rate output from the image sensor, for frames not provided with a given instruction, (ii) generates motion image data having the first frame rate based on the image data having the first frame rate output from the image sensor, for frames provided with a given instruction and (iii) processes the generated motion image data having the first frame rate and the generated motion image data having the second frame rate as a series of motion image data.
