PURPOSE:To execute photographing at a high speed and with a high picture quality by executing a scan by irradiating simultaneously radiant rays having each different energy on different parts of an object to be photographed, and accumulating the transmission quantity of the respective radiant rays at every detecting position. CONSTITUTION:A radiant ray irradiating means 1 irradiates monochromatic or narrow band radiant rays 4, 4 of two kinds or more on different positions of an object to be photographed 5. Also, a detecting means 6 scans a relative position of the radiant rays 4, 4 and the object to be photographed 5, and discriminates an detects the radiant ray which has transmitted through the object to be photographed 5 at every incident position. In this state, by executing an operation processing of the respective picture data by the radiant rays of two kinds or more of a storage means which has accumulated a detecting output of the means 6, contrast of the object to be photographed is emphasized, and a picture which has extracted only a specified part and has no noise can be obtained. |
