First Claim
Patent Images
1. A solid-state imaging array for electro-optically reading a one-dimensional symbol and for imaging a target, comprising:
- a) a two-dimensional subarray of first pixels extending along mutually orthogonal directions, for detecting light from a target and generating electrical signals indicative of a two-dimensional image of the target, each first pixel having a first aspect ratio;
b) a linear subarray of second pixels extending along one of said directions, for detecting light from a one-dimensional symbol and generating electrical signals indicative of the one-dimensional symbol, each second pixel having a second aspect ratio greater than said first aspect ratio; and
c) a single semiconductor chip on which both subarrays are provided.

Abstract
A semiconductor detector device for detecting optical code symbols includes no more than 512 pixels. Each of the pixels has an aspect ratio that is greater than 2 to 1 with a short dimension not greater than 8 microns. In a bar code reader, a sensor for detecting the field of view of the reader includes a single semiconductor device having a collection of surfaces configured as a set of no less than 256 and no more than 512 pixels. Each of the pixels has an aspect ratio that is greater than 2 to 1, with a short dimension not less than 2 microns and not greater than 8 microns.
