Abstract

Abstract A method and apparatus for high resolution character generation using a character generating apparatus having a first central processing unit with memory and input and output devices for processing and outputting character information, and a second central processing unit with different memory units and circuit arrangement electrically coupled with the first central processing unit for receiving character information and outputting processed character data information to produce resultant characters in various forms. The method includes the steps of preparing a character pattern description information for Chinese characters for being input into the character generating apparatus, and constructing a stroke table, a radical table and a specific symbol table for Chinese characters and other language letters for being stored in different memory units of the second central processing unit. Thereby, whenever character information is input, resultant characters can be quickly produced in any resolutions for various applications.

Claims Analysis

Total Claims: 4
Claim 1
Independent Claim 293 words
A method for storing Chinese character description information for use in a character generating apparatus, said method comprising the steps of: (1) constructing a stroke table for Chinese characters having a character type identification code designated thereto, and each stroke of the characters for each character type identification code being defined by coordinates of stroke height, width and curvature points for providing stroke description information therewith and having a stroke code associated with each stroke, said character type identification code, said stroke codes and said coordinates being systematically stored in a stroke table memory of said character generating apparatus through a software program, (2) constructing a character radical table for Chinese characters having a character type identification code designated thereto and a plurality of common radicals defined therewith, each radical being assigned a radical code and stroke codes defining the strokes making up each radical in the radical table; said character type identification code and said radical and stroke codes being systematically stored in a radical table memory of said character generating apparatus through a software program; (3) preparing character pattern description information for Chinese characters, each character including a character code, a character radical code based on said character radical table, and stroke codes based on said stroke table; said character code, character radical code, and stroke codes being systematically stored in a character pattern description memory of said character generating apparatus through a software program; and (4) constructing identification values for variation parameters which control the width of strokes stored in said stroke table and the size of radicals stored in said radical table of Chinese characters for input into said character generating apparatus to produce required characters; so that characters in different patterns can be quickly produced in high resolution.
Claim 2
Independent Claim 293 words
A method for storing Chinese character description information for use in a character generating apparatus, said method comprising the steps of: (1) constructing a stroke table for Chinese characters having a character type identification code designated thereto, and each stroke of the characters for each character type identification code being defined by coordinates of stroke height, width and curvature points for providing stroke description information therewith and having a stroke code associated with each stroke, said character type identification code, said stroke codes and said coordinates being systematically stored in a stroke table memory of said character generating apparatus through a software program, (2) constructing a character radical table for Chinese characters having a character type identification code designated thereto and a plurality of common radicals defined therewith, each radical being assigned a radical code and stroke codes defining the strokes making up each radical in the radical table; said character type identification code and said radical and stroke codes being systematically stored in a radical table memory of said character generating apparatus through a software program; (3) preparing character pattern description information for Chinese characters, each character including a character code, a character radical code based on said character radical table, and stroke codes based on said stroke table; said character code, character radical code, and stroke codes being systematically stored in a character pattern description memory of said character generating apparatus through a software program; and (4) constructing identification values for variation parameters which control the width of strokes stored in said stroke table and the size of radicals stored in said radical table of Chinese characters for input into said character generating apparatus to produce required characters; so that characters in different patterns can be quickly produced in high resolution.
Claim 3
Dependent Claim 73 words
A method according to claim 1 wherein said step of constructing identification values for variation parameters of strokes and radicals of Chinese characters further comprises the step of defining a character height and width identification value, a character type identification value, a stroke width identification value, a ratio of character height to width identification value, and a special symbol identification value, so that, various dimensions of characters can be produced in high resolution.
Claim 4
Dependent Claim 40 words
A method as claimed in claim 1 wherein said step of constructing identification values for variation parameters of strokes and radicals of Chinese characters further comprises the step of defining character dimensions from 16×16 up to 1024×1024 dot matrix forms.
