PROBLEM TO BE SOLVED: To achieve acquisition of correcting data for capturing pixels and correcting data for dose detecting pixels, without increasing time required for generating data, compared to time required for generating correcting data of each of the capturing pixels only.SOLUTION: An electronic cassette 1 includes: capturing pixels 60A each having a first sensor 13A which generates charge of an amount corresponding to a dose of emitted radiation; and dose detecting pixels 60B each having a second sensor 13B which generates charge of an amount corresponding to a dose of emitted radiation. During a period of time in which charge generated at the first sensor 13A is being stored in a first storage unit, charge generated at the second sensor 13B is stored in a second storage unit. Pixel values of the capturing pixels 60A that are at a signal level corresponding to an amount of charge stored in the first storage unit are acquired as first correcting data. Further, pixel values of the dose detecting pixels 60B that are at a signal level corresponding to an amount of charge stored in the second storage unit are acquired as second correcting data. |
