Camera having light emitting device, method for imaging skin and method for detecting skin condition using the same

A camera having light emitting devices, comprising:

• a substrate;
• a light emitting unit located on the substrate and irradiating light to a skin, the light irradiated by the light emitting unit being reflected by the skin;
• and
• a body coupled to the substrate and structured to expose the light emitting unit through a first optically transparent region formed on the body, the light irradiated to the skin through the first optically transparent region;
• a light receiving unit located on the body positioned to receive the reflected light;
• and
• a cover coupled to the body and located on sides of the light receiving units, the cover extending from the body to an upper area in a direction parallel to the substrate, the cover structured to expose the light receiving unit through a second optically transparent region formed on the cover, the reflected light received through the second optically transparent region, the second optically transparent region non-overlapping with the first optically transparent region, and
• wherein the light emitting unit comprises a plurality of sets of the light emitting devices;
• each of the sets comprises one or more light emitting devices to irradiate the light with substantially the same wavelength;
• and
• each of the sets sequentially irradiates the light with a wavelength that is different from other sets.
