Image acquiring device

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.
