An improved digital image sampling arrangement samples only one pixel of a predetermined region of pixels and assigns a density value to that pixel. The remaining, unsampled pixels of the region are then allocated density values based on the value of the sampled pixel using either a simple algorithm or an extrapolation algorithm. This improved arrangement provides more precise information about the sampled image than a prior art technique of merely enlarging each pixel by a predetermined factor.
