Abstract

PURPOSE:To perform efficient character recognition by keeping the balance between detection and segmentation processing and recognition processing, by using one detection and segmentation part (device detecting and segmenting characters) and recognition parts (specifying characters) in combination. CONSTITUTION:A character pattern entered in a document which is not shown in the figure is scanned by a photoelectric conversion part 1, quantized and stored 2. At a detection and segmentation part K, the pattern of one character is obtained by segmenting the stored pattern and stored 3. To the input pattern memory A1 a recognition part N1, for example, enabled to operate among recognition parts N1-Nn, the detected and segmented character pattern, etc., are transferred and a recognition start instruction is sent to the recognition part N1. Then, the recognition part N1 normalizes the character pattern to store the pattern in a pattern memory Sn for discrimination, and it is collated with reference patterns in a dictionary part 4 to select the kind of the character, thereby causing an interruption to an editing part H. Thus, those recognition parts are used in combination to perform efficient character recognition.
