Abstract:
1. A character image generation system for generating outline font based on character information including a character code and font information and displaying the outline font on a display with a prescribed number of pixels, comprising: an acquisition unit for obtaining the character information; a character outline information storage unit for storing character outline information corresponding to the character information; a subdivision unit for subdividing a curve expressed by the character outline information; a difference calculation unit for calculating a difference between coordinates at each end of the subdivided curve; a comparison unit for comparing the difference with a threshold value determined on the basis of a resolution of the display, to approximate a line element of the outline font to a straight line; and an outline coordinate calculation unit for sequentially calculating coordinates for each of the pixels, based on a result of the comparison and specifying the coordinates as the coordinates of an outline of each pixel, wherein subdivision unit performs the subdivision until a line element between the coordinates can be approximated to a straight line, based on the result of the comparison by the comparison unit.
