An imaging apparatus (1000) includes: an imaging device (110), a lens (120), an initial focal point detecting unit (130) detecting a positional relationship between the imaging device (110) and the lens (120) to specify an initial focal point which is a focal point found when an exposure start instruction is received from a user; a shift pattern determining unit (140) determining a shift pattern of the focal point, such that the focal point in an exposure time moves from the initial focal point, passes through both of a nearest end and a farthest end of a predetermined range of focus at least once, and returns to the initial focal point, the initial focal point being specified by the positional relationship between the imaging device (110) and the lens (120); and a shift control unit (150) moving one of the imaging device (110) and the lens (120) based on the shift pattern, such that the focal point moves from the initial focal point as soon as exposure starts, and arrives at the initial focal point again as soon as the exposure ends. |
