Skin observing apparatus
A skin observing apparatus capable of observing the skin texture, blotches caused from subcutaneous pigmentation and skin roughness caused from keratin abrasion by a single unit of image pick-up device without using a polarization plate for observing blotches or consumption articles such as a keratin sampling seal, the apparatus including an image pick-up head having an view hole to be in contact with a skin and, provided inside the image pick-up device, an image pick-up device for picking-up images of the skin through the view hole, and an illumination system comprising three systems, that is, a texture observing illumination system for irradiating a white light to the view hole along the image pick-up light axis (X), a keratin abrasion observing illumination system for irradiating a white light to the view hole from the lateral direction thereof, and a subcutaneous pigment observing illumination system for irradiating a UV-light to the view hole.
1. A skin observing apparatus, comprising:
an image pick-up head having a view hole formed at a top end thereof;
an image pick-up device that picks-up images of a skin through the view hole when the top end of the image pick-up head is in contact with the skin; and
an illumination system that irradiates illumination light on the skin, the image pick-up device and the illumination system being provided inside the image pick-up head,
wherein the illumination system comprises a texture observing illumination system that irradiates white light to the view hole along an axis of an image pick-up light, a keratin abrasion observing illumination system that irradiates a white light to the view hole from a lateral direction thereof, and a subcutaneous pigment observing illumination system that irradiates a UV-light to the view hole,
the texture observing illumination system comprises white light emitting elements arranged circularly at a periphery of the image pick-up light axis adjacent therewith,
the keratin abrasion observing illumination system comprises white light emitting elements arranged circularly outside of the white light emitting elements of the texture observing illumination system, and a reflection mirror that reflects illumination light of the white light emitting elements of the keratin abrasion observing illumination system and irradiates the same to the view hole from the lateral direction thereof, and
the subcutaneous pigment observing illumination system comprises UV-light emitting elements arranged circularly outside of the white light emitting elements of the texture observing illumination system.
2. A skin observing apparatus according to claim 1 , wherein the light emitting elements of the texture observing illumination system, the keratin abrasion observing illumination system and the subcutaneous pigment observing illumination system are arranged on a circular substrate disposed externally to a lens cylinder of the image pick-up device.
