    摘要： An LSI parallel image processor in which line buffers (20-i) and data-flow switching circuits (70) each requiring a larger amount of hardware in the prior art are incorporated into an LSI circuit, the image data delayed by the line buffers (20-i) is output from an image data output port (55), shift registers (31-i) each having a variable number of steps for preserving local image regions are intermittently shifted-in in accordance with applied clocks, and the contents of the shift registers (31-i) are sequentially read out.

    摘要： Coordinates of a handwritten pattern drawn on a tablet (100) are sequentially sampled by a pattern recognition unit (200) to prepare pattern coordinate data. Based on an area encircled by segments created by the sampled pattern coordinate data of one stroke and a line connecting a start point and an end point of the one-stroke coordinate data, the sampled pattern coordinate data of the one stroke is converted to straight line and/or curved line segments. The converted segments are quantized and normalized. The segments of the normalized input pattern are rearranged so that the input pattern is drawn in a predetermined sequence. Differences between direction angles for the rearranged segments are calculated. Those differences are compared with differences of the direction angles of the dictionary patterns read from a memory (300) to calculate a difference therebetween. The matching of the input pattern and the dictionary pattern is determined in accordance with the difference, If the matching fails, the first or last inputted segment of the input pattern is deleted or the sampled pattern coodinate data of the next stroke are added, to continue the recognition process.

    摘要： A natural language including Japanese, Korean, Chinese, etc., is suitably processed when an undefined word which is not registered in a dictionary appears in an input character train. When the undefined word appears, semantic analysis means (6) decides a semantic concept of the undefined word by using a case dictionary (12), and further by using a vocabulary hierarchy dictionary (13) which registers vocabularies in a hierarchy structure, the semantic analysis means (6) extracts a group of vocabularies (synonyms) corresponding to a lower concept of the semantic concept of the undefined word. The natural language processing can be achieved practically and efficiently with the dictionaries of a limited storage capacity.
