PURPOSE:To inhibit deterioration in case of regeneration of a character or pattern, by storing data for obtaining a curve closely analogous to the curved part of the profile of the character or pattern, and obtaining the curve closely analogous to the profile of the character or pattern on the basis of the data. CONSTITUTION:If the direction y of a drawing representing a character or pattern- storing or regenerating condition is aligned along the scanning direction of CRT or laser beams, distances between y1-y2 and y3-y4 are unblanking-controlled with scanning is done on a n-sound divided line along the direction x, to regenerate the character or pattern 1. That is, profile element data L (basic increase alpha, variation in increase beta, the number of divided lines N) are found with regard to each profile element Lm formed by proper division of the profile of the character or pattern, and a value yn corresponding to each point on the profile of the character or pattern is found on the basis of the seriesed profile element data, so that the original character or pattern can be regenerated. In this case, the final point of a preceding profile element such as profile elements Lm, Lm+1 is treated as the initial point of the following profile element, so as to obtain a continuous profile. |
