Abstract: A control method for an imaging element is a control method for an imaging element including a photoelectric converter and a peripheral circuit connected to the photoelectric converter. The control method for the imaging element includes receiving a predetermined input signal, and controlling the imaging element by switching between a normal imaging mode and a low power consumption mode based on the predetermined input signal. In the normal imaging mode, the imaging element is controlled to apply first voltage between the first electrode and the second electrode. In the low power consumption mode, the imaging element is controlled to apply second voltage between the first electrode and the second electrode and to stop part of operation of the peripheral circuit, the second voltage being larger than 0 V and smaller than the first voltage.

Abstract: An imaging device includes a pixel electrode, a counter electrode, a first quantum dot that includes a first core which generates first signal charge and a first shell, a second quantum dot that includes a second core which generates second signal charge and a second shell. In a case where the potential difference between the pixel electrode and the counter electrode is a first potential difference, the first signal charge does not pass through the first shell and is held in the first core and the second signal charge passes through the second shell and is collected by the pixel electrode. In a case where the potential difference between the pixel electrode and the counter electrode is a second potential difference which is larger than the first potential difference, the first signal charge passes through the first shell and is collected by the pixel electrode.
