Abstract: PROBLEM TO BE SOLVED: To accelerate the progress of inspection by a method wherein a subject is initially photographed without a filter means and an image signal in a picture dot area defined by the position of the filter means mounted afterwards within a radiation line is processed to be connected to the image signal yet to be processed for minimizing radiation dose applied. SOLUTION: A subject 4 undergoes a fluoroscopy by a low dose rate X-ray radiation, the X-ray radiation weakened by the subject 4 is turned to a signal by a detector 5 to be supplied to a means 6 for the formation of an image and output and stored into a memory means 9. Then, a filter means 8 is arranged in a radiation line 3 and the position of the filter means 8 pertaining to the detector is automatically detected using a means 10 for detecting position. Then, when the calculation of an expected image is performed per picture dot, the picture dots within only the processing area 'correlated' by the filter means 8 are taken into accounts. In other words, the signals corresponding to the picture dots alone are changed by inserting the filter means 8 into the radiation line 3 in the area of another photofluoroscopy.

Abstract: PROBLEM TO BE SOLVED: To obtain a film unit with a lens provided with a built-in stroboscope constituted so that a background is prevented from being photographed darkly by setting the guide number of a stroboscopic device to be equal to or under a specified value. SOLUTION: Since the tip part of an armature 16 abuts on both conductive patterns 151a and 151b forming a main switch on a printed circuit board 151, the main switch is in an on-state. Therefore, a stroboscope is charged and photographing with strobe light is executed. At the time of photographing with strobe light, exposure concerning the background at which strobe light does not get is decided only according to a diaphragm set to 7.3 as a T number and shutter speed set to 1/80. Therefore, the background farther than a maximum photographing distance in photographing with strobe light is exposed with reference exposure being EV 9.1, so that the background does not become a dark state. At such a time, the T number of a photographing lens at the time of photographing with strobe light is set to >=9 so that the capacitance of a capacitor for the stroboscope can be made small.
