Skin Area Detection Imaging Device

A skin area detecting imaging device comprising:

• multiple optical lenses for collecting light from an object to be imaged, which includes a human body with a skin area;
• a solid-state imaging element for imaging images formed by the optical lenses;
• shutter means for sequentially reading multiple images formed on the solid-state imaging element by the optical lenses, respectively;
• different image forming means for using light containing light (hereafter referred to as “different-wavelength light”) with two different wavelengths in near-infrared range to form, on the solid-state imaging element, two images different from each other in brightness of the skin area;
• storage means for storing, as two image information, the two images which are formed on the solid-state imaging element by the different image forming means, and are read and obtained by one time imaging operation of the shutter means;
• and
• skin area detection means for comparing the two image information stored in the storage means to detect, as the skin area, an area having difference in brightness larger than a predetermined value.
