摘要： An object of the present invention is to provide a character recognition apparatus for inferring the entire character string solely from a user-input handwritten keyword and displaying the inferred result as a candidate character string. The apparatus of the invention comprises: a word dictionary a6 storing word identification information and hierarchy information for layering a plurality of words into a hierarchy and for recognizing each of the words within the hierarchy; a character transition probability table a4 storing probabilities of transitions from any one character to another, and those pieces of the word identification information which correspond to combinations of characters resulting from the transitions; and an optimization unit for using the character transition probability table a4 in optimizing candidate character strings obtained by a recognition unit. The word dictionary a6 is searched for a word defined by the word identification information which corresponds to the optimized candidate character string, whereby the searched word is retrieved which applies to the hierarchy information and which has yet to be input.

摘要： A system using an input integrated flat panel display (5) of an integrated structure, having an input device (3, 13) for inputting through handwriting characters, graphics, or points and a flat panel display (2,12) laid upon the input device for displaying in accordance with an input point data input through handwriting. The frame memory (23) of a large screen having a display screen larger than that of the flat panel display is arranged to be read out through the input device of the input integrated flat panel display. In addition, the read-out contents of the large screen frame memory is arranged to be copied onto the flat display of the input integrated flat panel display. The input integrated flat panel display system can improve the man-machine performance while the amateur end user performs document processings, graphic processings and the like.

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： Disclosed is a communication system usable as a radio facsimile system that can transmit/receive information using the dedicated protocol independently of the radio wave status, as well as improve the transmission efficiency by restarting the subject communication even when it is interrupted and restarting the communication at the data just after the normally transmitted data. A communication controller (2) relays the communications between radio facsimile (1-1,...,1-n) and general facsimile (3-1,...,3-m), and changes protocols appropriately to the subject communication to reduce interruptions. In addition, when the subject communication is interrupted, the communication system can cope with it to continue the communication with means for re-dialing automatically at fixed intervals, means for adding the communication discrimination information for each communication, and means for notifying the communication discrimination information and the position information of the received data just before the interruption.
