Claim 0:
1. An image acquiring device comprising:
a light source portion; and
a sensor portion,
wherein the light source portion comprises:
an emitter portion having a plurality of groups of emitters configured to emit light of different wavelengths, wherein each of the plurality of groups corresponds to a respective wavelength of the different wavelengths;
a circuit portion configured to independently control a plurality of segments into which the emitter portion is divided; and
a driver portion configured to control the circuit portion so that the plurality of segments are driven at different strengths or at different times,
wherein each of the plurality of segments has a plurality of emitters arranged in a same pattern,
wherein the sensor portion is divided into regions to form a unit pixel that corresponds to a minimum unit for receiving light of a plurality of wavelengths, the unit pixel includes a plurality of pixels, and a wavelength pattern of the pixels in the unit pixel corresponds to a wavelength pattern of emitters provided in each of the plurality of segments, and
wherein pixels corresponding to wavelengths adjacent to each other in measurement are provided spatially adjacent to each other in the unit pixel.
