Abstract

A portable data collection device providing for optical character recognition. A housing defines an internal region and includes a user handle that allows a user to position the housing relative to an indicia carrying target. An imaging assembly includes a two dimensional imaging array supported within the internal region of the housing. The imaging assembly includes a capture circuit that generates a video signal representative of an image of a target zone. An optics assembly supported by the housing focuses an image of the target area onto the photosensor array. A character recognition processing circuit receives the video signal and categorizes the indicia on the target into a set of predefined characters. The character recognition processing circuit includes a discriminator for identifying a text region of the target and identifying individual character regions within the text region and a categorizer for identifying a character from a set of possible characters for an individual character region. The categorizer performs one or more tests based on pixel data within the individual character region.
