Abstract: According to an aspect, a detection device includes: a sensor including a first photodiode and a second photodiode; and a detection circuit configured to alternately detect an output of the first photodiode and an output of the second photodiode. Anodes of the first photodiode and the second photodiode are configured to be supplied with a first potential. A cathode of the second photodiode is configured to be supplied with a second potential lower than the first potential in a first period in which the output of the first photodiode is detected. A cathode of the first photodiode is configured to be supplied with the second potential in a second period in which the output of the second photodiode is detected.
