写真画像処理のマイクロコンピューターの利用による向上とランドサット映像への応用

抄録

In order to make good advancement in reproducibility, quantitativity and accuracy, we have developed a processing system which is composed of the following three main elements. 1) Each photographic processing is analyzed elaborately and simulated with the image analyzing system CIC 10 on the basis of Jones tone reproduction diagram. Then suitable package programs are developed. 2) Exposure is made by the computer controlled contact printer (photographic analyzing processor) provided with programs for various photographic processing. 3) Development and fixation of photographic materials are made by three kinds of automatic processors. In this report, tone control processing is examined mainly from the following two methods ; 1) control by effective exposure and density ranges, 2) control by contrast, and good results are obtained. Also the various compound processing systems in which tone control processing is combined with density slice, pseudo-color, hybrid pseudo-color and tone line processing are fully examined and the compound processing system suitable for analyzing LANDSAT imageries is developed. In every case it is confirmed that practically processed results are well consistent with the simulated results and the system is very useful for various purposes. Moreover LANDSAT MSS imageries of Ariake Sea are proccessed and analyzed by these procedures.
