Patent ID: 8786692

Claim:
An image processing device for detecting a skin area representing the skin of a person in an image obtained by imaging an object, comprising: a first light source configured to emit light having a first wavelength; a second light source configured to emit light having a second wavelength different from the first wavelength; an imager configured to image an object illuminated by the light having the first wavelength and image an object illuminated by the light having the second wavelength; detection circuitry configured to detect a skin area in either a first image obtained by imaging the object illuminated by the light having the first wavelength or a second image obtained by imaging the object illuminated by the light having the second wavelength based on the first image and the second image; and a substrate on which the first and second light sources are disposed integrally with the imager and the detection circuitry in such positions that the light sources are symmetric about the imager, wherein the first and second light sources are disposed on a straight line on the substrate in such positions that they are symmetric about the imager which is located in the middle of the straight line, the first light source includes a plurality of first light sources disposed on a first straight line parallel to the straight line, the second light source includes a plurality of second light sources disposed on a second straight line parallel to the straight line, a number of the plurality of first light sources and a number of the plurality of second light sources are determined based upon a difference between degrees of sensitivity the imager exhibits in receiving the light having the first wavelength and the light having the second wavelength, and the plurality of first light sources and the plurality of second light sources are disposed on the substrate such that an illuminance distribution of the light having the first wavelength coincides with an illuminance distribution of the light having the second wavelength.
