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.

Claims

1. A method for automatically discriminating between a dataform and a signature utilizing a hand held image reader, the hand held image reader having a two-dimensional image sensor, the method comprising:

collecting image data from an object utilizing the hand held image reader;

analyzing the image data to automatically discriminate between a dataform and a signature, the analyzing the image data including testing the image data for characteristics indicative of a signature, the testing the image data for characteristics indicative of a signature including testing the image data for the presence of curved elements; and

outputting processed image data.

2. The method according to claim 1 wherein outputting processed image data comprises outputting decoded barcode data.

3. The method according to claim 1 wherein outputting processed image data comprises outputting signature data.

4. The method according to claim 1 wherein analyzing the image data to automatically discriminate between a barcode and a signature comprises:

attempting to decode the image data as dataform data; and

testing the image data for characteristics indicative of a signature, if the attempt to decode the image data as dataform data fails.

5. The method according to claim 4 wherein the attempt to decode the image data as dataform data comprises an attempt to decode the image data as a one dimensional bar code.

6. The method according to claim 5 wherein the one dimensional bar code is a UPC bar code.

7. The method according to claim 4 wherein testing the image data for characteristics indicative of a signature includes at least testing the image data for the presence of curved elements.

8. The method according to claim 1 wherein analyzing the image data and

outputting processed image data comprise:

attempting to decode the image data as dataform data;

testing the image data for characteristics indicative of a signature;

outputting decoded dataform data if the attempt to decode the image data as dataform data is successful; and

outputting signature data if the test for characteristics indicative of a signature is successful.

9. The method of claim 1 wherein the testing the image data for the presence of includes utilizing a curvelet detector map.
