Abstract
A radiographic imaging apparatus includes a base, a signal line, a reader and a hardware processor. On the base board, pixels comprising respective radiation detecting elements and respective switching elements are arranged in a matrix. The signal line is connected through the switching elements. The reader reads the charges accumulated in the pixels at every predetermined lines as signal values of image data. The hardware processor measures a leak current flowing through the signal line and corrects the signal values based on leak current values including a leak current value obtained at a timing when (i) the number of lines which have been already read is greater than a predetermined number of lines and (ii) the number of lines which has not been read yet is greater than a predetermined remaining number of lines.
