A code reader includes an image acquisition system to acquire a plurality of images. A sensor detects motion of the code reader, and a processor is operatively coupled to the image acquisition system and the sensor. The processor performs a plurality of steps including associating a first detected motion data with one of the plurality of acquired images; associating a second detected motion data with a subsequent one of the plurality of acquired images; attempting to decode the one of the plurality of acquired images; determining if the second detected motion data is preferred over the first detected motion data; and attempting to decode the subsequent one of the plurality of acquired images when the second detected motion data is preferred over the first detected motion data.
