1. A digital image reading system adapted for reading a bar code symbol, said system comprising: an image sensing component; and a computer coupled to said image sensing component; wherein said system is adapted to acquire an image utilizing a first frame rate parameter, a first gain parameter, and a first exposure parameter; wherein said system is further adapted to adjust said first frame rate parameter to a second frame rate parameter responsively to an evaluation of said image acquired utilizing said first frame rate parameter, said first gain parameter, and said first exposure parameter, said second frame rate parameter being different from said first frame rate parameter; and wherein said system is further adapted to subject to a decode attempt for decoding of a bar code symbol a captured image captured utilizing said second frame rate parameter.
