The character recognition system identifies characters in each of three different fonts. Each character is scanned to obtain a binary word representation of the character. This representation is applied to three tables storing probability representations for each known character in the three fonts. Character comparison functions for each character in each font are produced which are stored in a buffer for later character identification and are also applied to three accumulators to provide three font comparison functions for the unknown character. From these functions the font is determined without, at that time, identifying the character. The results of a series of font identifications for a sequence of unknown characters are stored on a current basis, and from these results, font frequency functions are derived which are then employed to modify the character comparison functions that have been stored in the buffer. The modified character comparison functions are compared to identify the unknown character.
