Acceleration-based motion tolerance and predictive coding

A method of predicting the location of a region of interest within an image of a scannable object, the method comprising the steps of:

• providing a scanner having a processor and an image sensor;
• sensing in a viewing direction toward a scannable object, with an imaging plane being perpendicular to the viewing direction;
• setting a gain and an exposure time for the image sensor;
• capturing an image of the scannable object with the image sensor;
• 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, and when motion is detected, either increasing the gain or lowering the exposure time;
• outputting a velocity and a movement direction corresponding to the velocity;
• locating a region of interest in said captured image in response to the velocity and the movement direction;
• and
• scanning the captured image beginning with the region of interest.
