Abstract: To propose, in a skin detecting technique using light having a plurality of different wavelengths, an optimum spectral characteristic of an optical filter and optimum wavelengths lambda1, lambda2 of irradiation Detection subject light for preventing external light from entering an imaging section, provided is an image processing apparatus to detect a skin region representing a human skin from an image. The apparatus includes: a first irradiator; a second irradiator; an incident light limiter; a generator to generate a first image and a second image on the basis of the reflected light which enters from the subject through the incident light limiter; and a detector to detect the skin region on the basis of the first image and the second image.

Abstract: An image processing apparatus which detects a skin area indicating human skin on an image includes a first irradiation unit which irradiates a subject with light with a first wavelength, a second irradiation unit which irradiates the subject with light with a second wavelength, a generation unit which generates a first image based on reflected light incident from the subject when the light with the first wavelength is radiated and generates a second image based on reflected light incident from the subject when the light with the second wavelength is radiated, a correction unit which corrects at least one of a luminance value of the first image, a luminance value of the second image, and a threshold value to be compared to a difference between the luminance values of the first image and the second image, and a detection unit which detects the skin area based on the comparison result.

Abstract: An image processing device detecting a skin area representing the skin of a person from an image obtained by imaging an object, includes: imaging means for imaging the object; first illumination means for radiating light having a first wavelength from first and second positions determined based on the position of the imaging means; second illumination means for radiating light having a second wavelength different from the first wavelength from third and fourth positions determined based on the position of the imaging means; and detection means for detecting the skin area on either a first image obtained through imaging of the object performed by illuminating the object with the light having the first wavelength or a second image obtained through imaging of the object performed by illuminating the object with the light having the second wavelength.
