초록 ▼

An existing character, in a text defined in image form by data such as a two-dimensional array, is copied to add a new character to the text. The existing character is found by performing character recognition on a two-dimensional data array defining an image that includes part of the text, such as a page. The array can be obtained from a scanner. A word that is recognized as including characters of the type needed is tested to determine whether it can be divided into the correct number of characters. The word is divided by finding connected components in the part of the array in which the word was found during recognition. The connected components are grouped into sets, each set being likely to be a character. If the word can be correctly divided, character-size arrays for its characters are obtained and saved. One of the arrays for the character type of the new character is selected and used to produce an array for the word in which it is included. The new word\s array is then used to produce an array for a line in which the new word replaces an old word. The characters of the new word are spaced according to the spacing of the characters of the old word. The new character is positioned transverse to the line based on the transverse positioning of the existing character. The interword spaces of the line are adjusted. The line\s array is then used to produce data defining a modified version of the text in image form.

대표청구항 ▼

A method of operating a processor connected for accessing first text image data defining a first version of a text in image form, the first version of the text including a first character that is an instance of a first character type; the method comprising the steps of: operating on the first text image data to automatically obtain first character data defining the first character in substantially the same way as the first character is defined by the first text image data; and using the first text image data and the first character data to produce second text image data, the second text image data defining a second version of the text in image form, the second version of the text including a second character that is an instance of the first character type, the second charcter not appearing in the first version of the text, the step of using the first text image data and the first character data comprising the substep of using the first character data to produce the second text image data so that the second character is defined by the second text image data in substantially the same way as the first character is defined by the first character data.
