ABSTRACT:
A hand-held optical reader for reading 2D bar code symbols. The reader includes an illuminating system for illuminating the symbol and an optical system for focusing an image thereof on a 2D image sensor. The image sensor is of the type which allows its imaging parameters, such as exposure, to be controlled by external circuitry. The reader also includes an image sensor processor which sets and changes the imaging parameters used by the image sensor as necessary to meet predetermined image quality criteria and to reduce the time necessary to complete a read operation.
