摘要： An imaging apparatus comprises: a detecting unit 101 having a plurality of pixels 201 arranged in a matrix, each including a conversion element and a switch element for outputting a photoelectric conversion signal; a drive circuit unit 102 controlling the switching element such that the switching elements at least in one row are in the conducting state, and the switching elements in non-continuous rows are simultaneously in the conducting state; a signal processing unit 106 generating a detection signal 115 by adding or averaging the electrical signals output by the switch elements in non-continuous rows; a comparing unit 501 comparing the detection signal 115 with a threshold to determine whether the irradiation of radiation or light is started or ended; and a control circuit unit 108 controlling the drive circuit unit 102 or the signal processing unit 106 based on the determination of the comparing unit 501.
