DECODABLE INDICIA READING TERMINAL WITH INDICIA ANALYSIS FUNCTIONALITY

摘要

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.

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:
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 a processing time taken to successfully decode the indicia; andin response to the triggering event, transmitting the decoding result and the indicia readability rating via the communication interface.
