a substrate;

a sensor disposed on the substrate and including a blue light sensing element, a green light sensing element, and a red light sensing element;

a plurality of light emitting devices arranged around the sensor and configured to radiate a first light included in a first wavelength band and having a first wavelength to the object, the first wavelength being a wavelength at which a predetermined substance in the object has an absorption rate higher as compared to wavelengths other than the first wavelength; and

a filter disposed on a path through which light reflected from the object is incident on the sensor and configured to receive the reflected light that includes a portion of the first light and a second light having a second wavelength longer than the first wavelength, the filter further configured to block the portion of the first light and pass the second light,

wherein the filter is disposed to overlap the sensor along a first direction and the plurality of light emitting devices includes a first light emitting device and a second light emitting device that are disposed to be apart from each other on a line along a second direction perpendicular to the first direction,

wherein the filter and the line between the first light emitting device and the second light emitting device are axis-aligned together with the sensor, and

wherein the sensor configured to capture an image in response to receiving of the second light and extract a first value, a second value, or a third value of the image from the blue light sensing element, the green light sensing element, or the red light sensing element.
