    Abstract: According to an aspect, a detection device includes: photodiodes; a light source; a detection circuit configured to detect detection signals output from the photodiodes; and an exposure period adjusting circuit configured to determine an exposure period of the photodiodes. A relation between an output value output from the detection circuit and the exposure period comprises a linear region and a saturated region, and a gradient of the output value with respect to the exposure period in the saturated region is smaller than a gradient of the output value with respect to the exposure period in the linear region. The exposure period adjusting circuit is configured to determine the exposure period based on a first output value output from the detection circuit in a first exposure period, a second output value output from the detection circuit in a second exposure period, and a reference output value set in advance.

    Abstract: A detection device includes a ring-shaped housing wearable on a living body, a first light source provided inside the housing and configured to emit near-infrared light, an optical sensor capable of detecting the near-infrared light, and a control circuit configured to control lighting of the first light source. The control circuit is configured to measure a perfusion index of blood flow based on image data acquired by the optical sensor when being irradiated with the near-infrared light, determine the image data to be a vein image when the perfusion index is equal to or higher than a predetermined value, and determine the image data to be a dermatoglyphic image of a biological surface when the perfusion index is lower than the predetermined value.
