Abstract
A document recognition system includes various recognitive steps for document recognition, and various correctional steps corresponding to the recognitive steps. The operation modes of the system are a 'sequential mode' (sequential recognition operation) in which the respective recognitive steps are executed in 'step by step' fashion, an 'auto mode' (batch recognition operation) in which all the recognitive steps are collectively executed, and a 'retry mode' (re-recognition operation) in which the execution of any of the correctional steps is automatically followed by the execution of a necessary one of the recognitive steps. In the 'sequential mode', any of the recognitive steps having been executed can be shifted, not only to the correctional step corresponding to the executed recognitive step, but also to the correctional step preceding the execution. When an error is involved in a recognized result because the limits of a character line recognized by the system are incorrect, the user of the system corrects the limits of the character line. Then, the system can execute the necessary recognitive step again based on the corrected limits of the character line.
