Abstract
A character input apparatus accurately recognizes handwritten characters drawn one after another in a single input frame. A stroke matching unit obtains stroke information for each stroke in the inputted handwritten characters from the start/end area of the stroke in the input frame and the direction of the stroke, and detects stroke candidates for the stroke by comparing the stroke information with each set of stroke information in the stroke dictionary. An interval-based character detecting unit detects character candidates from detected stroke candidates by referring to the character dictionary that stores an stroke order for each character. With this construction, the apparatus is capable of accurately recognizing a plurality of characters drawn one after another in a single input frame.
