Title: Method for vectorizing line picture
Inventor: OTA JUNICHI
IPC: G06T9/00
Filed: 1989-04-03
Abstract: PURPOSE:To vectorize a line picture so as to minimize the division of the vector and to increase the overall processing speed by dividing and correcting previously the loop form of a contour vector into a simple form consisting of a simple graphic and a closed loop graphic and then obtaining the center line of the contour vector. CONSTITUTION:When a binary picture is vectorized, the loop form of a contour vector is previously divided and corrected into a simple form consisting of a simple graphic and a closed loop graphic by a dividing/correcting means, then, the center line of the contour vector is obtained. Thus the picture can be turned into a vector with minimized division of the vector even at a line crossing part like a composite graphic. In this case, the loop form of the contour vector can be divided and corrected into a simple form via such processes for extraction of a feature point, connection of nearby feature points, and correction of a contour loop. As a result, the loop form of the contour vector can be divided for correction at a high speed with use of the small number of memories. thus the overall high speed processing property is never deteriorated.

Title: Katakana-small character input system in word processor
Inventor: MOTOMURA SHIYUUJI
IPC: H03M11/14
Filed: 1984-04-26
Abstract: PURPOSE:To input a small character by depressing always the same key by providing the titled word processor with a table for registrating a word written by ''katakana'' [the square form of ''kana'' (Japanese syllabary)] including small characters and a word obtained by replacing the small characters in the word by ''katakana'' designation words at a pair. CONSTITUTION:A word written by ''katakana'' including small characters and a word obtained by replacing all the small characters by small character designation words are arrayed as a pair in the table 11. When ''FISH'' (fish) is to be inputted through a keyboard, the word in the column A which corresponds to said word to be inputted is depressed. Consequently, a table searching routine in a ''katakana'' small character conversion part 12 searches whether a word coincident with the input word exists in the registered words in the column A of the table 11 or not. When the coincident word is detected, the conversion part 12 outputs a word obtained by replacing the input word by a corresponding character string ''FISH'' in the column B. Consequently, the operation of a shift key or the like can be omitted.
