ABSTRACT:
A method for mapping sampled patterns into a lower resolution display device whereby a continuous image of the sampled pattern is reproduced. The method comprises determining the pixel location of each element of high resolution sampled data and the relative location within the pixel, deciding whether the pixels corresponding to the mapped data points should be included in the image, and graphically connecting selected pixels which are separated by one or more pixels. The process of pixel selection is aided by dividing each pixel into two separate areas, the boundary of which is determined by a predetermined geometric shape such as a diamond or circle which is entirely contained within a pixel. If a high resolution sampled data point or a connecting line falls within that predetermined geometric shape inside the pixel, then that pixel is selected, whereas data points falling outside the predetermined area within the pixel do not select that pixel for activation.
