Claim 12:
13. An operating method of a hyperspectral image sensor including an optical irradiator, an optical path adjustment element, an optical detector and a processor, the operating method comprising:
irradiating light to a partial region of an object by the optical irradiator;
adjusting, by the optical path adjustment element, a path of detection light generated in a plurality of different sub-regions included in the partial region in response to the irradiated light;
receiving, by the optical detector, the detection light transmitted from the optical path adjustment element;
generating, by the optical detector, a plurality of spectrum signals, each of the plurality of spectrum signals corresponding to a respective sub-region of the plurality of different sub-regions included in the partial region; and
generating, by the processor, a hyperspectral image of the partial region based on the plurality of spectrum signals,
wherein the optical irradiator comprises a first light source array including a plurality of first light sources arranged in a first direction, a second light source array including a plurality of second light sources arranged in the first direction and being separated from the first light source array and a transmissive window extending in the first direction and disposed between the first light source array and the second light source array, the first light source array being arranged in parallel to the second light source array,
wherein the adjusting the detection light comprises receiving the detection light from the plurality of different sub-regions in a third direction through the transmissive window and adjusting the path of the detection light so that the detection light is transmitted toward the optical detector in a second direction perpendicular to the first direction, the third direction being perpendicular to each of the first direction and the second direction,
wherein the optical detector comprises a lens, a spectrum filter and a spectrum signal generator,
wherein the receiving of the detection light comprises receiving, by the lens, the detection light generated in the plurality of different sub-regions included in the partial region,
wherein the generating of the plurality of spectrum signals comprises:
outputting, by the spectrum filter, a plurality of sub-spectrum filter signals for each sub-region of the plurality of different sub-regions based on the detection light, the plurality of sub-spectrum filter signals corresponding to a plurality of different wavelength bands for each sub-region of the plurality of different sub-regions, and
generating, by the spectrum signal generator, the plurality of spectrum signals for each sub-region of the plurality of different sub-regions based on the plurality of sub-spectrum filter signals.
