Abstract
There is described a system and method for automatically discriminating between different types of data with an image reader. In brief overview of one embodiment, the automatic discrimination feature of the present image reader allows a human operator to aim a hand held image reader at a target that can contain a dataform and actuate the image reader. An autodiscrimination module in the image reader in one embodiment analyzes image data representative of the target and determines a type of data represented in the image data.
Claims19
An image reader comprising:
- an image collection module for collecting images;
- and
- a processor module configured for:
- segmenting the first collected image into a plurality of regions;
- determining which of the plurality of regions includes a dataform;
- classifying the region including the dataform as a dataform region;
- determining which of the plurality of regions includes a signature;
- and
- classifying the region including the signature as a signature region
- identifying the dataform in the dataform region;
- identifying the signature in the signature region;
- processing the dataform region in an attempt to decode the dataform;
- and
- if the dataform is decoded, outputting the decoded dataform.

An image reader comprising:
- an image collection module for collecting images;
- and
- a processor module configured for automatically distinguishing data types by:
- segmenting a first collected image collected by the image collection module into a plurality of regions;
- independently determining which of the plurality of regions includes a dataform;
- classifying each region including a dataform as a dataform region;
- independently determining which of the plurality of regions includes a signature;
- and
- classifying each region including a signature as a signature region.

An image reader comprising:
- an image collection module for collecting images;
- and
- a processor module configured for:
- identifying a dataform in a first collected image collected by the image collection module;
- identifying data in the first collected image, wherein the data is not a dataform;
- processing the first collected image in an attempt to decode the dataform;
- if the dataform in the first collected image is not decoded, processing a subsequent image collected by the image collection module in an attempt to decode the dataform;
- and
- if the dataform in the first collected image is decoded, not processing a subsequent image collected by the image collection module in an attempt to decode the dataform.
