1. A camera system comprising:

  • a camera that captures an image frame with a prescribed exposure interval;

    a shooting field shifting mechanism that shifts a shooting field of the camera;

    a shift amount acquiring unit that acquires shift settings of the shooting field shifting mechanism; and

    a masking processor that masks a masking target within a captured image flame;

    wherein the masking processor includes;

    a first position computing unit that computes, based on the shift settings of the shooting field shifting mechanism at a first point in time during the exposure interval, a first relative position of the masking target relative to the shooting field at the first point in time;

    a second position computing unit that computes, based on the shift settings of the shooting field shifting mechanism at a second point in time during the exposure interval, a second relative position of the masking target relative to the shooting field at the second first point in time; and

    a mask area establishing unit that establishes a mask area to mask the masking target on the captured image flame, based on the first and second relative positions.
