Abstract
A process is described for digitising the relevant portion of a color image by a system with reduced memory capacity. The color image is scanned twice. The image signals (30) are sub-sampled (I) the first time and spatially reduced (II) the second time to the relevant image portion. The spatial data (35,36) for the relevant image portion are determined on an interactive work station (34), on which the sampled image signals (33) are displayed. Initial sampling and resampling by the scanner take place with the same spatial resolution. By carrying out the sub-sampling and the spatial reduction during scanning, an important saving of memory is realized. Owing to the fact that the color image is digitized in one single step, register faults are avoided.
