Claims
- 1. 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.
- 2. The device as defined in claim 1, wherein the pixels are arranged in a single row.
- 3. The device as defined in claim 1, wherein the pixels number no less than 256 pixels. The device as defined in claim 2, wherein the long dimension of each pixel is transverse to the row.
- 5. The device as defined in claim 1, and a package supporting the chip, the package occupying a volume of no more than 3.3 cubic centimeters.
- 6. The device as defined in claim 5, wherein the volume measures approximately 20.6 mm by 14.2 mm by 11.4 mm.
- 7. 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.
- 8. The reader as defined in claim 7, wherein the long dimension of each pixel extends lengthwise of a bar in the symbol.
- 9. The reader as defined in claim 7, wherein the pixels are arranged in a single row.
- 10. The reader as defined in claim 7, wherein the pixels number no less than 256 pixels.
- 11. The reader as defined in claim 9, wherein the long dimension of each pixel is transverse to the row.
- 12. The reader as defined in claim 7, and a package supporting the chip, the package occupying a volume of no more than 3.3 cubic centimeters.
- 13. The reader as defined in claim 12, wherein the volume measures approximately 20.6 mm by 14.2 mm by 11.4 mm.
