Abstract
An encoded information reading (EIR) terminal can comprise a microprocessor, a memory, and an EIR device including a two-dimensional imager. The EIR device can be configured to output raw message data containing an encoded message and/or outputting a decoded message corresponding to an encoded message. The EIR terminal can be configured, responsive to acquiring an image containing decodable indicia, to pre-process the acquired image and transmit the pre-processed image to an external decoding computer for decoding the decodable indicia.
Claims19
An electronic device, comprising:
- a microprocessor;
- a memory;
- and
- an imaging device;
- wherein the electronic device is configured to:
- acquire a first image containing decodable indicia with the imaging device;
- determine an adaptive scaling factor for scaling the acquired first image;
- dynamically adjust the adaptive scaling factor based on a decoding operation completion code received from an external computer, wherein the decoding operation completion code is associated with a second image decoded by the external computer;
- scale the acquired first image using the adjusted adaptive scaling factor;
- and
- transmit the scaled first image to the external computer, to decode the decodable indicia.
A method, comprising:
- acquiring a first image containing decodable indicia with an electronic device;
- responsive to acquiring the first image containing decodable indicia, scaling the acquired first image using an adaptive scaling factor;
- transmitting the scaled first image to an external computer for decoding the decodable indicia;
- and
- performing one or more iterations, each iteration comprising:
- dynamically adjusting the adaptive scaling factor based on a decoding operation completion code received from an external computer, wherein the decoding operation completion code is associated with a second image decoded by the external computer;
- scaling the acquired first image using the adjusted adaptive scaling factor;
- and
- transmitting the scaled first image to the external computer to be decoded at the external computer.
A non-transitory computer readable medium storing computer executable instructions thereon, that in response to execution by a processor, perform operations, comprising:
- acquiring a first image containing decodable indicia with an electronic device;
- responsive to acquiring the first image containing decodable indicia, scaling the acquired first image using an adaptive scaling factor;
- transmitting the scaled first image to an external computer for decoding the decodable indicia;
- and
- performing one or more iterations, each iteration comprising:
- dynamically adjusting the adaptive scaling factor based on a decoding operation completion code received from an external computer, wherein the decoding operation completion code is associated with a second image decoded by the external computer;
- scaling the acquired first image using the adjusted adaptive scaling factor;
- and
- transmitting the scaled first image to the external computer to be decoded at the external computer.
