US Patent 7770799 Optical reader having reduced specular reflection read failures

There is provided in one embodiment an optical reader having an image sensor array. In one embodiment, the image sensor array can include a first subset of pixels and a second subset of pixels. The first subset of pixels can be devoid of light polarizing filter elements, and the second subset of pixels can be light polarizing pixels including light polarizing filter elements. An optical reader can be configured to selectively read out image data from an image sensor array's light polarizing pixels. In one embodiment there is provided a portable apparatus having a first image sensor array and a second image sensor array.
