<p>PURPOSE:To discriminate between an entered noise and an effective stroke accurately by a simple procedure by deciding on the significance of an objective stroke which crosses a side of an observation frame and does not reach a noise depth decision frame on the basis of the inclination of the objective stroke. CONSTITUTION:A character pattern is stored in a figure memory 3, and concatenation components of the read character are extracted on the basis of the stored information in the figure memory 3 through the operation of a concatenation component extracting circuit 4 and a central processor 5 and stored in a concatenation component memory 7. The central processor 5 reads coordinate information on black bit constituting one concatenation component out of the concatenation component table in the memory 7 to discriminate whether the stroke contacts one side of the observation frame. Namely, the observation frame of the character to be read and the noise depth decision frame provided inside of the observation frame are used to decide on the significance of the objective stroke.</p> |
