In one aspect, a hyperspectral image measurement device is provided to include: a main body; an illumination module disposed in the main body and including LEDs having different peak wavelengths to irradiate light to a subject; a camera disposed on the main body and receiving light reflected from the subject to acquire an image of the subject; a barrel having a contact surface contacting the subject, the contact surface located to be spaced apart from the illumination module and the camera module by a predetermined distance; and a reference cover located on the contact surface and including a standard reflection layer for reflecting light irradiated from the illumination module toward the camera module.

Hyperspectral image measurement device and calibration method thereof, camera module and device for diagnosing skin and skin image processing method

Hyper-spectral image measurement device and calibration method therefor, photographing module and device for skin diagnosis, skin diagnosis method, and skin image processing method

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.

A portable apparatus for estimating air quality is provided. The portable apparatus includes a light source unit suitable for emitting incident light having a predetermined wavelength toward air to generate scattered light which is reflected by particles in the air, a light detection unit suitable for collecting information on the scattered light, and an arithmetic unit suitable for analyzing the information on the scattered light which is collected by the light detection unit. The arithmetic unit generates information on a size and a concentration of the particles in the air. Related methods are also provided.
