DETECTION DEVICE

Abstract: according to an aspect, a detection device includes: a sensor panel that has a detection area in which optical sensors are arranged; a light source unit comprising multiple types of light sources; a member on which an object to be detected is to be placed; and a detection circuit configured to obtain outputs of the optical sensors. the light sources configured to emit light in different colors are configured not to be turned on simultaneously but to be turned on in different periods. an exposure time when the optical sensor detects light differs between the light sources that emit light in different colors. the output of the optical sensor under conditions where the object to be detected is not placed falls within an output range corresponding to a predetermined target value, regardless of the color of the light emitted by one of the light sources that is turned on.
