Imaging apparatus, power control method, and power control program preliminary class

An imaging apparatus comprising:

• an imaging element including a pixel array that includes a plurality of pixels which are two-dimensionally arranged, a drive circuit of the pixel array, and a signal processing circuit that processes a signal read out from the pixel array by driving of the drive circuit;
• a power supply;
• a power supply control circuit that controls electric power supplied to the imaging element from the power supply;
• and
• a processor,
• wherein the processor is configured to control the power supply control circuit to stop the supply of electric power to a part of circuits of the imaging element from the power supply at a first timing after completion of the readout of the signal, to resume the supply of electric power to the part of the circuits at a third timing before a second timing that is a start timing of the readout of the signal from the pixel array performed after the first timing, and to variably control an interval between the second timing and the third timing.
