A method of predicting the location of a region of interest (30) within an image of a scannable object (13) comprising providing a scanner (12) having a processor (16) and an image sensor (22); sensing in a viewing direction toward a scannable object (13), with an imaging plane (P) being perpendicular to the viewing direction (A); capturing an image (32) of the scannable object (13) with the image sensor (22); sensing motion of the scanner within a motion sensor plane relative to the scannable object, the motion sensor plane being parallel to the imaging plane (P); outputting a velocity and a movement direction corresponding to the velocity; locating a region of interest (30) in said captured image (32) in response to the velocity and the movement direction; and scanning the captured image (32) beginning with the region of interest (30). |
