Abstract

A device can comprise a processor, a memory, an imaging subsystem configured to acquire an image of decodable indicia, a display, and a communication interface. The device can be configured, responsive to acquiring an image of one or more objects within a field of view of the imaging subsystem, to locate within the image and decode one or more decodable indicia. The device can be further configured to display the image on the display and visually mark the one or more successfully decoded decodable indicia. The device can be further configured, responsive to accepting user input selecting at least one decodable indicia of the displayed one or more decodable indicia, to transmit to an external computer at least one decoded message corresponding to the at least one decodable indicia.

Claims

1. A device, comprising:

an imaging subsystem having a field of view and configured to acquire an image;

a display; and

a communication interface;

wherein the device is configured to;

display an image of an object within the field of view of the imaging subsystem on the display;

locate within the acquired image one or more decodable indicia;

decode the one or more of the located decodable indicia;

visually mark one or more successfully decoded decodable indicia on the display;

accept user input selecting one of the successfully decoded decodable indicia in the displayed image; and

transmit, with the communication interface, to an external computer the decoded message corresponding to the selected decodable indicia.

2. The device of claim 1, wherein the device is a smart phone, a tablet computer, and/or a personal digital assistant.

3. The device of claim 1, wherein the imaging subsystem comprises:

a two-dimensional image sensor configured to output an analog signal representative of light reflected by an object located within the field of view of the imaging subsystem;

an amplifier configured to output an amplified analog signal by amplifying the analog signal read out of the image sensor; and

an analog-to-digital (A/D) converter configured to convert the amplified analog signal into a digital signal representing the acquired image.

4. The device of claim 1, wherein the device is configured to accept user input indicating an order in which decoded messages corresponding to two or more decodable indicia are to be transmitted to the external computer.

5. The device of claim 1, wherein the device is configured to:

accept user input selecting within the displayed image at least one decodable indicia which is not marked as successfully decoded; and

decode the selected at least one decodable indicia.

6. The device of claim 1, wherein the device is configured to transmit, with the communication interface, to an external computer at least one image comprising the selected decodable indicia.

7. A method, comprising:

displaying, with an imaging subsystem, an image of an object within a field of view of the imaging subsystem on a display;

locating, with a device comprising the imaging subsystem, within the acquired image one or more decodable indicia;

decoding, with the device, the one or more of the located decodable indicia;

visually marking, with the device, one or more successfully decoded decodable indicia within the displayed image;

accepting, with the device, user input selecting one of the successfully decoded decodable indicia in the displayed image; and

transmitting, with the device, to an external computer the decoded message corresponding to the selected decodable indicia.

8. The method of claim 7, comprising:

displaying, with the device, two or more decodable indicia in the acquired image on the display;

accepting, with the device, user input indicating an order in which decoded messages corresponding to the displayed two or more decodable indicia are to be transmitted to the external computer.

9. The method of claim 7, comprising:

accepting user input selecting within the displayed image at least one decodable indicia which is not marked as successfully decoded; and

decoding the selected at least one decodable indicia.

10. The method of claim 7, wherein visually marking, with the device, one or more successfully decoded decodable indicia within the displayed image comprises highlighting the one or more successfully decoded decodable indicia within the displayed image.

11. The method of claim 7, wherein visually marking, with the device, one or more successfully decoded decodable indicia within the displayed image comprises rendering a bounding box around the one or more successfully decoded decodable indicia within the displayed image.

12. The method of claim 7, wherein visually marking, with the device, one or more successfully decoded decodable indicia within the displayed image comprises rendering a visual marker around a center of the one or more successfully decoded decodable indicia within the displayed image.

13. The method of claim 7, comprising transmitting with the communication interface, to an external computer at least one image comprising the selected decodable indicia.

14. The method of claim 7, wherein the device comprises a mobile computer.

15. A computer-readable storage medium comprising executable instructions capable of configuring one or more processors for:

displaying, with an imaging subsystem, an image of an object within a field of view of the imaging subsystem on a display;

locating, with a device comprising the imaging subsystem, within the acquired image one or more decodable indicia;

decoding, with the device, the one or more of the located decodable indicia;

visually marking, with the device, one or more successfully decoded decodable indicia within the displayed image;

accepting, with the device, user input selecting one of the successfully decoded decodable indicia in the displayed image; and

transmitting, with the device, to an external computer the decoded message corresponding to the selected decodable indicia.

16. The computer-readable storage medium of claim 15, in which the executable instructions are capable of configuring one or more processors for:

displaying, with the device, two or more decodable indicia in the acquired image on the display;

accepting, with the device, user input indicating an order in which decoded messages corresponding to the displayed two or more decodable indicia are to be transmitted to the external computer.

17. The computer-readable storage medium of claim 15, in which the executable instructions are capable of configuring one or more processors for:

accepting user input selecting within the displayed image at least one decodable indicia which is not marked as successfully decoded; and

decoding the selected decodable indicia.

18. The computer-readable storage medium of claim 15, wherein visually marking, with the device, one or more successfully decoded decodable indicia within the displayed image comprises highlighting the one or more successfully decoded decodable indicia within the displayed image.

19. The computer-readable storage medium of claim 15, wherein visually marking, with the device, one or more successfully decoded decodable indicia within the displayed image comprises rendering a bounding box around the one or more successfully decoded decodable indicia within the displayed image.

20. The computer-readable storage medium of claim 15, wherein visually marking, with the device, one or more successfully decoded decodable indicia within the displayed image comprises rendering a visual marker around a center of the one or more successfully decoded decodable indicia within the displayed image.
