<p>A method for improving scanning accuracy of small fonts. The method first sharpens the data (210) and then up samples (222, 224) the data to increase the size of characters. Sharpening occurs first in the y direction (402-412) by examining pixels above and below each pixel as it is processed and adjusting the pixel. After sharpening the data, the data is upsampled in the y direction by creating a new scan row (702-716) of pixels between each existing scan row of pixels, by averaging (708-712) the gray scale level of the pixels of the two scan rows and placing the average value in the new scan row. In a similar manner, the data is increased within each scan row by adding a new pixel between each of the existing pixels (902-918). The new pixel between each pair of pixels is formed by averaging the value of the two pixels within the pair. <IMAGE></p> |
