Character pattern generation
First Claim
1. A character processing apparatus comprising:
- memory means for storing control point information representing an outline of one of a plurality of characters including a character which comprises a plurality of radicals each comprising a plurality of line elements, minimum reproducible pixel size information representing a minimum reproducible pixel size for each radical, and skipping order information representing skipping order of each of a plurality of horizontal or vertical bands obtained by dividing each radical;
comparing means for comparing size information of a character to be generated and the minimum reproducible pixel size information for that character stored in said memory means;
determining means for determining a band to be skipped, on the basis of the plurality of pieces of skipping order information for the character to be generated stored in said memory means in response to a comparison by said comparing means showing that the size information of the character to be generated is smaller than the minimum reproducible pixel size information for that character; and
generating means for generating a character pattern on the basis of the control point information for each band not determined by said determining means as being a band to be skipped, and generating no character pattern on the basis of the control point information for the band determined by said determining means to be skipped.

Abstract
A character processing apparatus for recognizing coordinate information expressing a character, an exterior outline, an interior outline, a horizontal line and a vertical line; classifying the coordinate information expressing a character, the exterior outline, the interior outline, the horizontal line and the vertical line, and then determining a pair of the horizontal line and the vertical line; and setting a skipping order at the time of low pixel so as to be converted into character data for a bit map development composed of a control point coordinate for expressing the outline of the subject character, band information and coordinate value information about the control point which is not included in the band information.

11. A character processing method using a memory for storing control point information representing an outline of one of a plurality of characters including a character which comprises a plurality of radicals each comprising a plurality of line elements, minimum reproducible pixel size information representing a minimum reproducible pixel for each radical, and skipping order information representing skipping order of each of a plurality of horizontal or vertical bands obtained by dividing each radical, said method comprising the steps of:
-
comparing size information of a character to be generated and the minimum reproducible pixel size information for that character stored in the memory; determining a band to be skipped, on the basis of the plurality of pieces of skipping order information for the character to be generated stored in the memory in response to a comparison in said comparing step showing that the size information of the character to be generated is smaller than the minimum reproducible pixel size information for that character; and generating a character pattern on the basis of the control point information for each band not determined as a band to be skipped, and generating no character pattern on the basis of the control point information for the band determined to be skipped. - View Dependent Claims (12, 13, 14, 15, 16, 17, 18, 19, 20, 22)
