Abstract

There is described an imaging apparatus having an imaging assembly that includes an image sensor. The imaging apparatus can capture a frame of image data having image data corresponding to a first set of pixels of the image sensor. The imaging apparatus can capture a frame or image data having image data corresponding to a second set of pixels of the image sensor.

Claims

1. A stationary position apparatus for use in reading an indicia, wherein the stationary position apparatus comprises in combination:

an imaging assembly comprising an image sensor having a plurality of pixels and optics focusing an image onto the image sensor, wherein the image sensor is a two dimensional image sensor;

wherein the stationary position apparatus is operable to capture a relatively smaller sized frame of image data and responsively to a processing of the relatively smaller sized frame of image data capture one or more relatively larger sized frame of image data for use in attempting to decode the indicia, the one or more relatively larger sized frame of image data having image data corresponding to a predetermined set of pixels of said image sensor and representing a larger portion of the indicia than image data of the relatively smaller sized frame of image data;

wherein the stationary position apparatus is adapted to be maintained in a stationary position, and wherein the stationary position apparatus is operable for use in reading of indicia on articles moved in relation to a field of view of the stationary position apparatus.

2. The stationary position apparatus of claim 1, wherein the stationary position apparatus is operable to capture the one or more relatively larger sized frame conditionally on the condition that the processing of the relatively smaller sized frame does not result in a successful decoding of the indicia.

3. The stationary position apparatus of claim 1, wherein the image sensor is a CMOS image sensor.

4. The stationary position apparatus of claim 1, wherein the one or more relatively larger sized frame of image data is a full frame of image data.

5. The stationary position apparatus of claim 1, wherein the stationary position apparatus includes an illumination assembly.

6. The stationary position apparatus of claim 5, wherein the illumination assembly includes a laser, and wherein said illumination assembly is adapted to project an aiming pattern.

7. The stationary position apparatus of claim 1, wherein the stationary position apparatus includes an illumination assembly and wherein said illumination assembly includes a white LED.

8. The stationary position apparatus of claim 1, wherein the stationary position apparatus includes a scan stand.

9. The stationary position apparatus of claim 1, wherein the indicia is operative to attempt to decode a 1D bar code indicia.

10. The stationary position apparatus of claim 1, wherein the indicia is operative to attempt to decode a 2D bar code indicia.

11. A stationary position apparatus for use in reading an indicia, wherein the stationary position apparatus comprises in combination:

an imaging assembly comprising an image sensor having a plurality of pixels and optics focusing an image onto the image sensor, wherein the image sensor is a two dimensional image sensor;

wherein the stationary position apparatus is operable to capture a first frame of image data having image data corresponding to a first set of pixels of the image sensor and responsively to a processing of the first frame of image data capture a second frame of image data having image data corresponding to a second set of pixels of the image sensor for use in attempting to decode the indicia, wherein the second set of pixels is different from the first set of pixels and wherein the pixels of the second set of pixels are adaptively determined responsively to a processing of the first frame of image data,

wherein the stationary position apparatus is adapted to be maintained in a stationary position, and wherein the stationary position apparatus is operable for use in reading of indicia on articles moved in relation to a field of view of the stationary position apparatus.

12. The stationary position apparatus of claim 11, wherein the stationary position apparatus includes an illumination assembly.

13. The stationary position apparatus of claim 11, wherein the stationary position apparatus includes an illumination assembly and wherein said illumination assembly includes a white LED.

14. The stationary position apparatus of claim 11, wherein the stationary position apparatus includes a scan stand.
