A radiographic imaging apparatus includes: a hardware processor; and a correlated double sampling circuit including first and second sample-and-hold circuits. The hardware processor causes the first sample-and-hold circuit to perform sampling for a predetermined period of time; causes the second sample-and-hold circuit to perform sampling for a period of time longer than time constant of the second sample-and-hold circuit; obtains correction information based on a difference output from the correlated double sampling circuit every predetermined number of times the sampling in a non-conductive state is performed; calculates a correction value based on the obtained correction information; corrects, with the calculated correction value, a signal value that is the difference output from the correlated double sampling circuit after the second sample-and-hold circuit performs the sampling via a conductive state; and generates a radiograph based on the corrected signal value.
