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. ## Claims ### Claim 1 A code reader comprising: an image acquisition system, the image acquisition system to acquire low resolution images and high resolution images, and to acquire a brightness level for at least one of the low resolution images and high resolution images;

determining if a brightness level of the first image at the first exposure time provides an acceptable exposure time for image decoding; determining if a motion level of the code reader is above or below a motion level threshold, the motion level threshold based on the acceptable exposure time; when the motion level of the code reader is below the motion level threshold, and when the exposure time provides the acceptable exposure time, determining if the first image is a low resolution image or a high resolution image;
