Abstract

A semiconductor device for imaging optical code symbols comprises no more than 1024 pixels, wherein each of the pixels has an aspect ratio that is greater than 2 to 1 with a short dimension not greater than 4 μm and not less than 2 μm, wherein preferably the pixels are arranged in a single row. The semiconductor may have a collection surface configured as a set of no less than 256 and no more than 1024 pixels. Also provided is a bar code reader including a sensor for imaging a field of view of the reader comprising a single semiconductor device as described above.
