Cloud-based system for processing of decodable indicia
First Claim
Patent Images
1. A terminal, comprising:
- a microprocessor;
a memory;
an imaging device configured for acquiring an image of decodable indicia;
wherein the terminal is configured for;
pre-processing the image of decodable indicia acquired by the imaging device;
transmitting the pre-processed image to a server on a server side of a data decoding system for decoding the decodable indicia;
receiving a decoded message from the server, wherein the decoded message comprises only a source identifier of additional data; and
transmitting the source identifier to an external computer to retrieve additional data from the external computer that is locally connected to the terminal.

Abstract
A data decoding system can comprise a client computer including an imaging device and one or more servers executing at least one decoding process. The client computer can be configured to acquire an image of decodable indicia and to process the acquired image by:
- (i) identifying one or more areas of interest within the image;
- (ii) cropping the image based on the identified areas of interest;
- (iii) clipping one or more images from the image based on the identified areas of interest;
- (iv) increasing or reducing a pixel resolution of at least part of the image;
- (v) converting the image to a grayscale image or to a monochrome image; and/or
- (vi) compressing the image using a compression algorithm.
The decoding process can be configured, responsive to receiving a decoding request comprising the processed image, to decode the decodable indicia and to transmit the decoding operation result to the client computer.

9. A server communicatively coupled to a network, wherein:
-
a client computer is communicatively coupled to the network, the client computer comprises an integrated imaging device and/or a peripheral imaging device, and the client computer is configured to acquire and process an image of a decodable indicia and transmit the processed image to the server; the server is configured for; executing at least one decoding process; while executing the at least one decoding process and responsive to receiving a decoding request comprising an image of a decodable indicia, decoding the decodable indicia into a decoded message; and while executing the at least one decoding process and responsive to completing a decoding operation, transmitting a decoded message to the client computer, wherein the decoded message comprises only a source identifier that is transmitted by the client computer to an external computer locally connected to the client computer to retrieve additional information corresponding to the source identifier from the external computer. - View Dependent Claims (10, 11, 12, 13, 14, 15)

16. A method for decoding a decodable indicia, the method comprising:
-
receiving a decoding request from a client computer, the decoding request comprising an image of a decodable indicia; decoding the decodable indicia in the image; and transmitting, to the client computer, a decoded message comprising only a source identifier corresponding to the decodable indicia, the source identifier transmitted by the client computer to an external computer locally connected to the client computer to retrieve additional information corresponding to the source identifier from the external computer. - View Dependent Claims (17, 18, 19)
