    Abstract: According to an aspect, a detection device includes: photodiodes configured to perform detection in a detection period, a power supply control circuit, and power supply circuits configured to supply, to each photodiode, a first potential or a second potential based on a control signal from the power supply control circuit. The photodiodes are respectively provided for partial detection areas of a detection area. The power supply control circuit is configured to detect an output level of a signal output from each of the partial detection areas when the first potential is supplied to the photodiodes during a setting period different from the detection period, and control the power supply circuits so as to supply the second potential to the photodiode of the partial detection area in which the output level of the signal is equal to or higher than a predetermined threshold during the detection period.
