Abstract

A system for selectively reading code symbols includes a code-symbol-capturing subsystem for acquiring information about code symbols within the code-symbol-capturing subsystem'"'"'s field of view. The system also includes a code-symbol-decoding processor that detects a marked region of interest within the code-symbol-capturing subsystem'"'"'s field of view. After initialization, the code-symbol-decoding processor decodes only those code symbols falling within the marked region of interest.

Claims

1. A system for reading code symbols, comprising:

a code-symbol-capturing subsystem for acquiring information about code symbols within the code-symbol-capturing subsystem'"'"'s field of view; and

a code-symbol-decoding processor configured for;

detecting a marked region of interest within the code-symbol-capturing subsystem'"'"'s field of view; and

decoding code-symbol information within the marked region of interest within the code-symbol-capturing subsystem'"'"'s field of view;

wherein the code-symbol-decoding processor is configured to disregard code-symbol information that is outside the marked region of interest.

2. The system for reading code symbols according to claim 1, wherein the code-symbol-capturing subsystem is an imaging subsystem for capturing images within the imaging subsystem'"'"'s field of view.

3. The system for reading code symbols according to claim 1, wherein the code-symbol-capturing subsystem is a laser scanning subsystem for scanning code symbols within the laser scanning subsystem'"'"'s field of view.

4. The system for reading code symbols according to claim 1, wherein the code-symbol-decoding processor is configured for detecting the region of interest in response to a user-positioned marker.

5. The system for reading code symbols according to claim 4, wherein the user-positioned marker is a code symbol.

6. The system for reading code symbols according to claim 4, wherein the user-positioned marker is a signal-enhancing marker.

7. The system for reading code symbols according to claim 4, wherein the user-positioned marker is a signal-diminishing marker.

8. A system for reading code symbols, comprising:

a code-symbol-capturing subsystem configured for;

detecting a marked region of interest within the code-symbol-capturing subsystem'"'"'s initial field of view; and

adjusting the code-symbol-capturing subsystem'"'"'s initial field of view to an adjusted field of view that corresponds to the region of interest; and

acquiring information about code symbols within the code-symbol-capturing subsystem'"'"'s adjusted field of view that corresponds to the region of interest; and

a code-symbol-decoding processor for processing code-symbol information acquired by the code-symbol-capturing subsystem.

9. The system for reading code symbols according to claim 8, wherein the code-symbol-capturing subsystem is an imaging subsystem for capturing images of code symbols.

10. The system for reading code symbols according to claim 8, wherein the code-symbol-capturing subsystem is a laser scanning subsystem for scanning code symbols.

11. The system for reading code symbols according to claim 8, wherein the code-symbol-capturing subsystem is configured for detecting the region of interest in response to a user-positioned marker.

12. The system for reading code symbols according to claim 8, wherein the user-positioned marker is a code symbol.

13. The system for reading code symbols according to claim 8, wherein the user-positioned marker is a signal-enhancing marker.

14. The system for reading code symbols according to claim 8, wherein the user-positioned marker is a signal-diminishing marker.

15. A method for selectively reading code symbols, comprising:

providing a code symbol reader having a code-symbol-capturing subsystem for acquiring information about code symbols within the code-symbol-capturing subsystem'"'"'s field of view, and a code-symbol-decoding processor for decoding code-symbols captured by the code-symbol-capturing subsystem;

detecting a marked region of interest within the code-symbol-capturing subsystem'"'"'s field of view; and

decoding only those code symbols that are within the marked region of interest.

16. The method for selectively reading code symbols of claim 15, wherein the code-symbol-decoding processor is configured to disregard code-symbol information that is outside the marked region of interest.

17. The method for selectively reading code symbols of claim 15, comprising:

adjusting the code-symbol-capturing subsystem'"'"'s initial field of view to an adjusted field of view that corresponds to the region of interest; and

acquiring information about code symbols within the code-symbol-capturing subsystem'"'"'s adjusted field of view that corresponds to the region of interest.

18. The method for selectively reading code symbols of claim 15, comprising:

marking a region of interest with a user-positioned marker;

wherein the user-positioned marker is a finger.

19. The method for selectively reading code symbols of claim 15, comprising:

marking a region of interest with a user-positioned marker;

wherein the user-positioned marker is a signal-enhancing marker.

20. The method for selectively reading code symbols of claim 15, comprising:

indicating the marked region of interest to a user of the code symbol reader by a region-of-interest indicator.
