<p>PROBLEM TO BE SOLVED: To perform an appropriate automatic exposure control even when a communication delay occurs in a radiocommunication section between a radiation image capturing apparatus and an interface device.SOLUTION: An electronic cassette 1 detects applied radiation to capture a radiation image, and intermittently, wirelessly transmits dose information representing a dose of the detected radiation to an interface box 220. The interface box 220 generates a cumulative dose signal having a signal level according to the cumulative dose of the radiation applied to the electronic cassette 1 on the basis of each of the received dose information, and when determining that there is a delay in reception timing of the dose information, adjusts the signal level of the cumulative dose signal so as to reduce an error generated in the cumulative dose signal caused by the delay.</p> |
