A Rescanner with Photographic Color Readout

Summary Readout limitations in the original rescanner (an analog computer system for scan record analysis) prompted us to explore photographic color recording as a readout. This resulted in a definite quantitative relationship between colors in rescan record and the opacity of an original record, averaged over a definite area. The contour-map nature of the final record seems to be a useful way of presenting re-processed, or “computed”, scan information. Preliminary results are gratifying, and though they indicate the need for a better and faster system, it appears that this method of computer analysis of scan records is promising.
