Abstract: PROBLEM TO BE SOLVED: To adjust a gain or the like of a camera within a range where a skin region can be detected.
SOLUTION: An LED 21a radiates light of a first wavelength, an LED 21b radiates light of a second wavelength, and a camera 22 images a subject. In a state where the subject is not irradiated with the light of the first and second wavelengths, based on an external light image obtained by imaging the subject with the camera 22, a control part 41 adjusts a parameter of the camera 22 within such a range as to meet a skin detection enabled condition for detecting a skin region. A calculation part 42 and a binarization part 43 detect the skin region based on a first captured image obtained by imaging with the adjusted camera 22 at a time when the subject is irradiated with the light of the first wavelength, and a second captured image obtained by imaging with the adjusted camera 22 at a time when the subject is irradiated with the light of the second wavelength. The present invention may be applicable to a computer which detects a shape of a subject from e.g., a captured image obtained by imaging the subject.

Abstract: PROBLEM TO BE SOLVED: To detect distance to a user with high accuracy, based on a captured image obtained by imaging the user.
SOLUTION: An LED 21a irradiates a subject with light having a first wavelength; an LED 21b applies light having a second wavelength differing from the first wavelength to the subject; a camera 22 images the subject irradiated with the light having the first wavelength to generate a first captured image and images the subject irradiated with the light having the second wavelength to generate a second captured image; a binarization unit 43 detects a skin region of the subject, based on the first and second captured images; and a coordinates detection unit 44 calculates distance to the subject, based on a differential absolute value of luminance values of the corresponding pixels in the skin region on the first and second captured images. The present invention can be applied to, for example, computers, or the like for calculating the distance to the user from the captured images obtained by imaging the user.

Abstract: PROBLEM TO BE SOLVED: To uniformly distribute light having a wavelength λ1 and light having a wavelength λ2 with the same illuminance even when using a plurality of light sources.SOLUTION: A first light source control part 51 supplies driving power to a first light source group 52 and adjusts its current value to control irradiation timing and illuminance of the first light source group 52. A second light source control part 53 supplies the driving power to a second light source group 54 and adjusts its current value to control irradiation timing and illuminance of the second light source group 54. Respective light source groups are individually controlled in this manner, so that illuminance of light having the wavelength λ1 and illuminance of light having the wavelength λ2 can be uniformly distributed in an irradiation range of the first light source group 52, an irradiation range of the second light source group 54, and an area where the irradiation range of the first light source group 52 and the irradiation range of the second light source group 54 overlap each other. This invention can be applied to a skin detection device.
