To improve the characteristics of an imaging apparatus such as power consumption and reading speed of the photon counting type imaging apparatus using an avalanche diode.SOLUTION: An imaging apparatus comprises a plurality of photoelectric conversion elements each including an avalanche diode and a counter. The imaging apparatus is provided with first selection means in correspondence with a first photoelectric conversion element. The imaging apparatus is provided with second selection means in correspondence with a second photoelectric conversion element. In a first mode, the imaging apparatus is controlled to be in a state in which a signal from the first photoelectric conversion element is read out by the first selection means, and controlled to be in a state in which a signal from the second photoelectric conversion element is not read out by the second selection means. In a second mode, the imaging apparatus causes the second selection means to control the second photoelectric conversion element controlled to be in the state in which the signal is not read out to be in the state in which the signal is read out.SELECTED DRAWING: Figure 4
