Abstract
Pattern recognition apparatus and method which provides plural pattern recognition modes, one of which is selected in accordance with characteristics of an unknown pattern to be recognized. The pattern recognition apparatus includes a pattern recognizer having plural recognition modes for comparing an unknown pattern with at least one known pattern, and a selector for selecting one of the plural recognition modes based on characteristics of the unknown pattern. In one aspect, the selection of one of the plural recognition modes is based on font size, font type and image quality, and in another aspect, selection of the recognition mode is based on the results of prior pattern recognition operations. The pattern recognition apparatus may be provided in a stand-alone device, and this device may interface to a local area network bus. Alternatively, the pattern recognition apparatus may be distributed such that individual components thereof are provided independently on a local area network bus and provided with individual servers for interface with stand-alone computers. In the case where computers perform character processing or word processing, a preview mode may be provided so that the results of character recognition may be previewed before transmitting image information to a remote location.
