Abstract

A multi-media device for reading either magnetically encoded cards and passbooks or printed information on checks, bills or other documents. The device uses a magnetic and an optical read head and parallel processing to distinguish between magnetic and OCR (optical character recognition) input. The system optically recognizes four different fonts and one font combination, and identifies which font is being read. The present system stores, in parallel, the information obtained from a magnetic read head and an optical read head in separate magnetic and optical processing units. The optical unit processes the video from the optical read head and determines if the input is readable as one of the valid character fonts.

Media and Multi-Font Character Recognition

A multi-media device for reading either magnetically encoded cards and passbooks or printed information on checks, bills or other documents. The device uses a magnetic and an optical read head and parallel processing to distinguish between magnetic and OCR (optical character recognition) input. The system optically recognizes four different fonts and one font combination, and identifies which font is being read. The present system stores, in parallel, the information obtained from a magnetic read head and an optical read head in separate magnetic and optical processing units. The optical unit processes the video from the optical read head and determines if the input is readable as one of the valid character fonts. The magnetic processing unit simultaneously processes the magnetic read head data and stores the results in a magnetic recognition buffer. If the input is not readable by the optical processor, the information in the magnetic recognition buffer is returned as the output data of the system. The optical processor executes a separate font recognition logic for each allowable font. The recognition results are stored in separate buffers corresponding to the individual fonts. The input data type is determined to be optical data if one or more recognition logics recognize the input with less than a specified number of rejected characters. When the input is determined to be optical data, the font recognition buffer wit...
