An imaging apparatus includes: an image sensor that captures a subject image formed to generate image data; a recorder that records first image data showing images sequentially captured by the image sensor at a shooting period; and a controller operates the image sensor with a frame period shorter than half period of the shooting period, to generate one or plural frames of second image data by capturing in another frame period than the frame period for capturing the first image data within the shooting period. The second image data shows an image used for control in the imaging apparatus, captured with a setting different from a setting for the first image data. The control is performed based on a plurality of frames of image data including the one or plural frames of second image data, the plurality of frames being obtained by multiple times of capturing in the shooting period.
