In a document in which a plurality of data items of different kinds are mixed, when one data item is edited, the relative positional relation to other data items is prevented from being destroyed, whereby information is prevented from becoming meaningless or from being changed. For example, when an edit is carried out on one data item, a deviation amount of that data item is derived and a shift process by the same amount is effected on the other data items, whereby the relative positional relation can be maintained among the data items.

An information processing method and apparatus which uses a memory storing stroke data forming one character together with respective stroke order information to display each stroke data based on the stored stroke order information at an arbitrary speed. In addition, a display speed changing instruction is input into the apparatus and the display speed of the stroke data is changed in response to the display speed changing instruction. In addition, stroke data stored in correspondence to the stroke order information of an input stroke order number is read from the memory and displayed. Further, the stroke data can be displayed under different display conditions such that the stroke order information stored in correspondence to the stroke data can be distinguished from each other.

Information processing method and apparatus

Two different recognition processing units respectively perform a plurality of different recognition processing operations for the pattern to be recognized input from a character input unit, and acquire a plurality of recognition candidates and recognition scores. An accuracy calculation unit converts the recognition scores obtained by the two recognition processing units into accuracies based on a scale common to the plurality of different recognition processing operations using parameters stored in a parameter storage unit. A determination unit generates a recognition candidate sequence by determining the order of the recognition candidates obtained by the two recognition processing units on the basis of the accuracies converted by the accuracy calculation unit.

The present invention is based on an observation that a range of information desired to select, may differ, according to a mode selected (for example, in a case where a plurality of information pieces are grouped, an erasing operation might be performed only on part of the group). The present invention determines, where appropriate, an automatic changeover to designate either a single piece of information or a whole group of pieces of information as a range of information to be selected as a processed object, according to a mode selected.

Information processing in which grouped information is processed either as a group or individually, based on mode

A character recognition apparatus is provided with a recognition dictionary that stores the strokes of standard characters in an order that is in accordance with a predetermined rule for deciding the order of each stroke by the positional relationship of each stroke. A plurality of strokes are stored on a storage medium in an order in accordance with the predetermined rule. The plurality of strokes stored on the storage medium and each stroke of the standard characters stored in the recognition dictionary are compared. The character constructed by the plurality of strokes is recognized based upon the results of comparison.

A pattern recognizing apparatus which recognizes patterns on the basis of a recognition dictionary includes a frequency information updating device for updating a plurality of items of frequency information, respectively assigned to a plurality of reference patterns, in accordance with a reference to at least one of the plurality of reference patterns during recognition and a recognition dictionary reconfiguration device for reconfiguring the recognition dictionary based on a difference between the updated frequency information.

Method and apparatus for developing a character recognition dictionary

In a character input method and apparatus, data can be input by a simple operation using a displayed keyboard. The keyboard is displayed on the picture surface of a display unit, and data is input by designating a key position on the keyboard. The designated key position is detected based on a designated coordinate position on the keyboard. The corresponding operation is identified based on coordinate positions subsequently input on the keyboard, and a specific key code is generated based on the detected key position and the identified operation.

Character input method and apparatus arrangement

A threshold value for identifying similar characters is set at will from a keyboard. It is determined whether a character entered on a character input panel by a pen is a similar character and, if the entered character is judged to be a similar character, a feature quantity of this character is calculated. The calculated feature quality and the set threshold value are compared. On the basis of the comparison, the character determined to be a similar character is identified as being in any of a plurality of character groups of similar characters.

Character recognition apparatus and method

A character registered in a user's dictionary by a user is outputted prior to other character in a character recognition process. To realize this operation, the character recognition apparatus comprises a user's dictionary (105) and a basic dictionary (103), and a user's unique handwritten character is registered in the user's dictionary (105). In addition, a priority order associated with the handwritten character is simultaneously designated to a priority designation section (109) and stored in a priority storing section (108). When character recognition operation is performed, the basic dictionary (103) and the user's dictionary (105) are utilized; and the recognition result from the basic dictionary and the recognition result from the user's dictionary are adjusted at a result adjusting section (107), by utilizing the priority obtained from the priority storing section (108). Those characters registered in the user's dictionary (105) are outputted prior to other characters in a subsequent recognition operation.
