DECODABLE INDICIA READING TERMINAL WITH INDICIA ANALYSIS FUNCTIONALITY
First Claim
1. An indicia reader comprising:
- an image sensor for generating a signal;
an imaging lens for focusing light on the image sensor;
a communication interface for transmitting data; and
a microprocessor communicatively coupled to the image sensor and the communication interface, the microprocessor being configured for;
processing the signal generated by the image sensor in an attempt to decode indicia represented in the signal;
in response to a triggering event, generating a decoding result;
in response to the triggering event, determining an indicia readability rating corresponding to the decoding result based on a number of attempts to decode an indicia and/or a processing time taken to decode the indicia; and
in response to the triggering event, transmitting the decoding result and the indicia readability rating via the communication interface.

Abstract
A decodable indicia reading terminal can comprise a multiple pixel image sensor, an imaging lens configured to focus an image of decodable indicia on the image sensor, an analog-to-digital (A/D) converter configured to convert an analog signal read out of the image sensor into a digital signal, a communication interface, and a microprocessor configured to output decoded message data corresponding to the decodable indicia by processing the digital signal. The decodable indicia reading terminal can be configured, responsive to a triggering event, to transmit via the communication interface a decoding result and an indicia readability rating. The triggering event can be provided by a failure to detect decodable indicia, the indicia readability rating being less than a pre-defined threshold, exceeding a pre-defined time period to decode decodable indicia, a user interface action, and a command received via said communication interface.
