A camera having light emitting devices includes a light emitting unit configured to irradiate light to a skin, and a light receiving unit configured to receive reflected light which is generated when the light irradiated by the light emitting unit is reflected from the skin. The light emitting unit comprises a plurality of sets of the light emitting devices, and each of the sets includes one or more light emitting devices which are configured to irradiate the light with the same wavelength. In addition, each of the sets is configured to sequentially irradiate the light and irradiate light with a wavelength that is different from other sets. By using the camera, it is possible to obtain information of the skin for each wavelength by sequentially irradiating light with wavelengths different from other sets, reduce distorted information, and perform an accurate diagnosis.
