摘要： A Bezier curve constituting outline font data represents a curve by four coordinate values of a start point, an end point, and two control points. The curve is represented by two coordinates of the start point and the end point in collinear approximation, and by three coordinates of the start point, an intersecting point of two lines, and the end point in bi-linear approximation. In curve pattern approximation, when 32 curve patterns are prepared, the curve is represented by 5-bit data of two coordinates of the start point and the end point, and a pattern number. By effectively employing these three kinds of processes, it is possible to represent a Bezier curve constituting the outline font data with a reduced data volume.

摘要： Having an outline font data readout unit read a correction subject pixel and surrounding pixels thereof, referring to the already stored pre-correction and post-correction brightness value pattern data that are related to the read correction subject pixel and surrounding pixels, deriving a post-correction brightness value pattern uniquely from among candidates for a post-correction brightness value pattern of an appropriate value as post-correction brightness value, determining the optimal post-correction brightness value from the uniquely derived post-correction brightness value pattern and outputting correction data based on the determined optimal post-correction brightness value, thereby changing a brightness value of a pixel within a character image giving a look of unnaturalness automatically to a brightness value not giving a look thereof.

摘要： A difference of coordinate values stored adjacent to each other is compressed by means of a statistical coding system when reading out outline font data storing coordinate values necessary for drawing a contour of a character in order of drawing the contour in a clockwise or counterclockwise direction and also a category of a line connecting a pair of coordinates simultaneously, followed by compressing the coordinate values of the outline font data. A value of a result of subtracting “A−1” from a difference of coordinate values is determined to be a difference value of coordinates if the difference of coordinate value is equal to or greater than a certain value A, and a code expressing the difference value of “0” is added in front of the codes of difference values that are smaller than the value A in the case of a category of line connecting adjacent coordinates to each other being a straight line.

The character image generation system subdivides a curve expressed by character outline information corresponding to inputted character information, calculates the difference between coordinates at each end of the subdivided curve, compares the difference with a predetermined threshold value and sequentially calculates coordinates for each pixel, based on this comparison result.
