An imaging apparatus (100) of the present invention includes a shift control unit (22) shifting an object-space focal point of the imaging apparatus (100) by shifting an image-space distance; and a shift pattern determining unit (21) determining a shift pattern of the image-space distance shifted by the shift control unit (22) in a frame period. The shift pattern determining unit (21) determine the shift pattern such that: a shift speed of the image-space distance increases from zero during an acceleration period included in the frame period; the image-space distance shifts at a constant speed during a constant speed period; and the shift speed of the image-space distance decreases to zero during a deceleration period, and each of the acceleration period and the deceleration period has a duration equal to or longer than one-tenth of the frame period.
