Abstract:
1. An algorithm for use by a digital image reader/decoder, comprising the steps: (i) acquire an image at an initial frame rate parameter, gain parameter, and exposure time parameter, (ii) evaluate the image, (iii) determine whether the system is operating at a fastest frame rate, and, if not, (iv) calculate a new exposure time parameter to provide a desired image illumination, (v) calculate a maximum frame rate parameter that will support the new exposure time, (vi) calculate a new exposure setting parameter that will support the new exposure time at the maximum frame rate, (vii) determined whether the image is acceptable and, if yes, (viii) output and decode the image, and provide the parameters in (iv-vi) to the imager as new initial parameters, and (ix) return to (i).
