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.

A semiconductor device for imaging optical code symbols, comprising:
- a chip having no more than 1024 pixels, wherein each of the pixels has a long dimension, a short dimension, and an aspect ratio that is greater than 2 to 1, the short dimension of each pixel being not greater than 4 μm and not less than 2 μm.
A bar code reader for reading a symbol having bars spaced apart along a longitudinal direction, each bar extending lengthwise along a transverse direction perpendicular to the longitudinal direction, comprising:
- a sensor for imaging a field of view of the reader, the sensor comprising a single semiconductor chip having no more than 1024 pixels, wherein each of the pixels has a long dimension, a short dimension, and an aspect ratio that is greater than 2 to 1, the short dimension of each pixel being not greater than 4 μm and not less than 2 μm.
