Recent]y, the extraction of precious information out of picture and image enhancement for the human to recognize the image more easily (those experiments are called image processing) has been tried with electronic computers. The authors constructed the Ube Technical College Picture Information Processing System (U-PIPS) for use in these same kinds of experiments, and are obtaining very satisfactory results. Although the information processing schemes are spreading widely, when they are restricted to mono-chrome picture processing, the schemes are able to enhance the picture for easy recognition, based on the differences of intensities. Some examples are; drawing a equi-density curve; equi-temperature distribution pattern made from infra-red picture; equi-light density pattern made from ordinary photographs and so on. In the case of mono-chrome picture processing, especially, drawing equi-dcnsity patterns, we were able to get almost all desired results from only by simple analogue electronic circuits without huge electronic computers. And in this particular case, by not using electronic computers the time needed to process the picture is shorter and the portability makes the device possible to be used in many more situations since huge computer are not necessary. In addition, the processed results are much more easily and quickly obtaind. Refering to the above discussion the authors developed a high precision equi-density curve drawing device. This device is modified from a rotating drum, moving scanner-type facsimile which draw a maximum of 10 equi-density lines per processing. The outlines of the device and processing examples such as surface temperature distribution patterns of two-dimensionally heated materials by measuring the heating iron and light intensity distribution patterns on a wall in a class room are shown in this paper.
