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;

    a sensor to detect motion of the code reader;

    a processor operatively coupled to the image acquisition system and the sensor, the processor to perform the steps of;

    instructing the image acquisition system to acquire a first image at a first exposure time;

    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; and

    if the first image is a high resolution image, attempting to decode the high resolution image.
