Abstract

An imaging reader for, and a method of, imaging targets, include a solid-state imager supported by the reader and having an array of image sensors for capturing return light from a target over a field of view, and for generating image data corresponding to the target; an application specific integrated circuit (ASIC) operatively connected to the imager via an image data bus over which the image data is transmitted from the imager to the ASIC, and via a system bus over which system data for controlling operation of the reader is transmitted, the ASIC being operative for combining the image data and the system data to form combined data; and a controller operatively connected to the ASIC, for receiving and processing the combined data from the ASIC.

Claims

1. An imaging reader for imaging targets, comprising:

a solid-state imager supported by the reader and having an array of image sensors for capturing return light from a target over a field of view, and for generating image data corresponding to the target;

an application specific integrated circuit (ASIC) operatively connected to the imager via an image data bus over which the image data is transmitted from the imager to the ASIC, and via a system bus over which system data for controlling operation of the reader is transmitted, the ASIC being operative for combining the image data and the system data to form combined data; and

a controller operatively connected to the ASIC, for receiving and processing the combined data from the ASIC.

2. The reader of claim 1, wherein at least one of the controller and the ASIC is operative for determining the system data.

3. The reader of claim 1, wherein the system bus between the imager and the ASIC is bi-directional.

4. The reader of claim 1, wherein the ASIC is operatively connected to the controller via a combined data bus over which the combined data is transmitted from the ASIC to the controller, and via another system bus over which the system data for controlling operation of the reader is transmitted between the ASIC and the controller.

5. The reader of claim 3, wherein the other system bus between the ASIC and the controller is bi-directional.

6. The reader of claim 1, wherein the ASIC forms the combined data by appending the system data to the image data.

7. The reader of claim 1, wherein the ASIC forms the combined data by overwriting the system data on part of the image data.

8. The reader of claim 1, wherein the controller processes the combined data by separating, and separately processing, the system data and the image data.

9. An imaging reader for imaging targets, comprising:

an imaging system having a solid-state imager supported by the reader and having an array of image sensors for capturing return light from a target over a field of view, and for generating image data corresponding to the target, the imaging system being operative for combining the image data and system data for controlling operation of the reader to form combined data; and

a controller operatively connected to the imaging system, for receiving and processing the combined data from the imaging system.

10. A method of imaging targets with an imaging reader, comprising the steps of:

capturing return light from a target over a field of view of a solid-state imager having an array of image sensors, and generating image data corresponding to the target;

operatively connecting an application specific integrated circuit (ASIC) to the imager via an image data bus over which the image data is transmitted from the imager to the ASIC, and via a system bus over which system data for controlling operation of the reader is transmitted, and combining the image data and the system data with the ASIC to form combined data; and

receiving and processing the combined data from the ASIC at a controller operatively connected to the ASIC.

11. The method of claim 10, and a step of determining the system data by at least one of the controller and the ASIC.

12. The method of claim 10, and a step of configuring the system bus between the imager and the ASIC to be bi-directional.

13. The method of claim 10, and a step of operatively connecting the ASIC to the controller via a combined data bus over which the combined data is transmitted from the ASIC to the controller, and via another system bus over which the system data for controlling operation of the reader is transmitted between the ASIC and the controller.

14. The method of claim 13, and a step of configuring the other system bus between the ASIC and the controller to be bi-directional.

15. The method of claim 10, wherein the step of forming the combined data is performed by appending the system data to the image data.

16. The method of claim 10, wherein the step of forming the combined data is performed by overwriting the system data on part of the image data.

17. The method of claim 10, wherein the step of processing the combined data is performed by separating, and separately processing, the system data and the image data.
