Abstract
Signals corresponding to the color content of an original, generated by scanning the original mounted on a rotating drum, are sampled and held at a coarse or low-resolution scanning rate. The number of samples per line (revolution) and the number of revolutions along which scanning is performed correspond to a raster scan of a video display. The signals are converted into digital signals and stored in a memory. The rate of sampling is adjusted so that samples from an entire frame of the original fill the memory. The stored signals are converted to analog signals, adjusted by a color computer to simulate a printing process and displayed at a raster scan rate on a video display. The apparatus according to the invention may be a scanner-previewer combination to achieve a previewing of the original, or may be a scanner with additional apparatus.
