CAMERA SYSTEM
First Claim
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.

Abstract
A camera system includes a camera, a shooting field shifting mechanism, a shift amount acquiring unit, and a masking processor that masks a masking target within a captured image flame. The masking processor includes first and second position computing units, and mask area establishing unit. The first and second position computing units compute, based on the shift settings of the shooting field shifting mechanism, first and second relative positions of the masking target relative to the shooting field. The mask area establishing unit establishes a mask area to mask the masking target on the captured image flame, based on the first and second relative positions.

7. A method of controlling a camera system including a camera that captures an image frame with a prescribed exposure interval, and a shooting field shifting mechanism that shifts a shooting field of the camera, the method comprising the steps of:
-
(a) acquiring first shift settings of the shooting field shifting mechanism at a first point in time during the exposure interval; (b) acquiring second shift settings of the shooting field shifting mechanism at a second point in time during the exposure interval; (c) computing a first relative position of the masking target relative to the shooting field at the first point in time, based on the first shift settings; (d) computing a second relative position of the masking target relative to the shooting field at the second point in time, based on the second shift settings; and (e) establishing a mask area to mask the masking target on the captured image flame, based on the first and second relative positions. - View Dependent Claims (8, 9, 10, 11, 12)
