1. An encoded information reading (EIR) terminal comprising:
- a microprocessor;
a memory;
an EIR device including a two-dimensional imager, said EIR device configured to perform one of;
outputting raw message data containing an encoded message, outputting a decoded message corresponding to an encoded message;
wherein said EIR terminal is configured, responsive to acquiring an image containing decodable indicia, to pre-process the image containing decidable indicia including;
determining a quality of said image using one or more methods of determining image quality; and
ascertaining that said quality of said image satisfies one of;
a pre-determined condition, an adaptive condition;
wherein, only if said image satisfies one of said pre-determined condition or said adaptive condition, said ER terminal is further configured to transmit said image to an external computer for decoding said decodable indicia.

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.
