PHOTOGRAPHING APPARATUS, PHOTOGRAPHING SYSTEM, PHOTOGRAPHING METHOD AND STORAGE MEDIUM

摘要

PROBLEM TO BE SOLVED: To provide a photographing apparatus capable of efficiently photographing and always providing a good photographing image by enabling a measurement of a sensitivity state of an image receiving means for forming the image in a simple, accurate and reproducible state. SOLUTION: The first image receiving means 106 forms the photographing image of a subject based on an incident light (incident X-ray), and outputs a signal of the image. The second image receiving means 108 is provided on a photodetecting surface of the means 106 and outputs a signal based on the incident light. A measuring means 116 measures the sensitivity state of the incident light of the means 106 based on a correlation between an output corresponding to an incident light quantity of the means 106 at a same position and an output corresponding to an incident light quantity of the means 108.
