Abstract

A portable document scanner (PDS) is provided that need not be in communication with a local computer. The PDS includes an image scanner for scanning an input document to generate a scan image, a processor, a wireless communications port that enables wireless communications with remote computing services, and a memory that stores instructions for execution by the processor to locally process the scan image. Such processing includes, for example, extracting identity, position, and/or orientation of one or more optical semaphores from the scan image, where the extracted semaphores include (1) optical characters including letters, numerals, and/or punctuation, (2) informational indicia including bar codes, data graphs, pictures, and/or icons, and (3) document formatting indicators including lines, bars, arrows, and/or grids. The extracted semaphore data is communicated to a remote computing service via the wireless communications port. The processing operations may be managed by the user through an integrated display interface.

Claims

1. A portable document scanner comprising:

an image scanner for scanning an input document to generate a scan image;

a processor;

a wireless communications port that enables wireless communications with remote computing services;

a user interface adapted to permit a user to select and to interact with software processes being executed by said processor; and

a memory that stores instructions for execution by the processor, the instructions including instructions that, when processed, cause said processor to (a) extract identity, position, and/or orientation of one or more optical semaphores from the scan image, where the extracted semaphores include (1) optical characters including letters, numerals, and/or punctuation, (2) informational indicia including bar codes, data graphs, pictures, and/or icons, and/or (3) document formatting indicators including lines, bars, arrows, and/or grids, (b) communicate semaphore data to a remote computing service via the wireless communications port, and (c) perform image processing operations on the scan image, said image processing operations including at least one of auto cropping, scaling, rotating to deskew, background enhancement, image format conversion, despeckling, and modifying a histogram of the scan image under user control via said user interface.

2. The portable document scanner of claim 1, further comprising a housing including the image scanner, the processor, the wireless communications port, the user interface, and the memory.

3. The portable document scanner of claim 1, wherein the memory further stores instructions for execution by the processor that, when processed, cause said processor to enable a user to provide via said user interface pre-scan settings including selection of pixel density;

how color is digitized, image storage or export formats, and/or storage or export features.

4. The portable document scanner of claim 1, wherein the memory further stores instructions for execution by the processor that, when processed, cause said processor to initiate a business process to be performed by the processor based upon one or more of the extracted semaphore data and to communicate a status of the business process to a user via said user interface.

5. The portable document scanner of claim 1, wherein the memory further stores instructions for execution by the processor that, when processed, cause said processor to determine document image quality and to communicate the document image quality to a user via said user interface.

6. A portable document scanner comprising:

an image scanner for scanning an input document to generate a scan image;

a processor;

a wireless communications port that enables wireless communications with remote computing services; and

a memory that stores instructions for execution by the processor, the instructions including instructions that, when processed, cause said processor to extract identity, position, and/or orientation of one or more optical semaphores from the scan image, where the extracted semaphores include (1) optical characters including letters, numerals, and/or punctuation, (2) informational indicia including bar codes, data graphs, pictures, and/or icons, and/or (3) document formatting indicators including lines, bars, arrows, and/or grids, and further including instructions that, when processed, cause said processor to communicate semaphore data to a remote computing service via the wireless communications port and to process the scan image to automatically append to the semaphore data further data including geolocation information related to the scan image.

7. A portable document scanner comprising:

an image scanner for scanning an input document to generate a scan image;

a processor;

a wireless communications port that enables wireless communications with remote computing services; and

a memory that stores instructions for execution by the processor, the instructions including instructions that, when processed, cause said processor to extract identity, position, and/or orientation of one or more optical semaphores from the scan image, where the extracted semaphores include (1) optical characters including letters, numerals, and/or punctuation, (2) informational indicia including bar codes, data graphs, pictures, and/or icons, and/or (3) document formatting indicators including lines, bars, arrows, and/or grids, and further including instructions that, when processed, cause said processor to communicate semaphore data to a remote computing service via the wireless communications port and to detect the availability and connectivity state of the wireless communications port.

8. The portable document scanner of claim 7, wherein the memory further stores instructions for execution by the processor that, when processed, cause said processor to perform image processing of the scan image when the wireless communications port is determined by the processor to be unavailable or disconnected.

9. A method of scanning a document with a portable document scanner, comprising:

enabling a user to select and to interact with software processes being executed by said processor via a user interface of the portable document scanner;

communicating the semaphore data to a remote computing service via a wireless communications port of the portable document scanner, and

enabling a user to select, via said user interface, image processing operations to be performed on the scan image, said image processing operations including at least one of auto cropping, scaling, rotating to deskew, background enhancement, image format conversion, despeckling, and modifying a histogram of the scan image.

10. The method as in claim 9, further comprising enabling a user to select, via said user interface, pre-scan settings including selection of pixel density;

how color is digitized, image storage or export formats, and/or storage or export features.

11. The method as in claim 9, further comprising enabling a user to initiate, via said user interface, a business process to be performed by the processor based upon one or more of the extracted semaphore data, and communicating a status of the business process to the user via said user interface.

12. The method as in claim 9, further comprising determining, using said processor, document image quality, and communicating the document image quality to a user via said user interface.

13. A method of scanning a document with a portable document scanner, comprising:

scanning the document with an image scanner to generate a scan image;
