Abstract

Abstract A method and apparatus is provided for identifying imperfections in a person's facial, forearm or hand skin and for recommending an appropriate remedial cosmetic. The method includes providing an apparatus having a programmable computer, a camera connected to the computer, at least one visible wavelength light source for separately generating at least two different color images and at least one ultraviolet wavelength light source for an ultraviolet light image. Further, the method includes placing the ultraviolet and color images into a program of the computer and processing the images for pinpointing areas of skin requiring preventative treatment including those with skin damage. A remedial set of cosmetic products can thereby be recommended.

Claims Analysis

Total Claims: 15
Claim 1
Independent Claim 160 words
A method for identifying imperfections in a person's skin and for recommending appropriate remedial cosmetics, the method comprising: (i) providing an apparatus which includes: (a) a program for storing information; (b) a camera connected to the program; (c) at least one visible wavelength light source associated with the camera for separately generating at least two different color images; and (d) at least one ultraviolet wavelength light source associated with the camera for generating an ultraviolet light image; (ii) positioning a body part of a person within a photographical area of the light sources and camera; (iii) obtaining the at least two different color and ultraviolet light images of the body part which information is placed into the program; (iv) processing the images via the program and thereby identifying personal aspects selected from the group consisting of skin attributes, signs of skin damage and defects; and (v) recommending a cosmetic productmost suitable to the person based upon the identified personal aspects.
Claim 2
Dependent Claim 24 words
The method according to claim 1 further comprising the step of shielding the person's eyes from flashes of light emanating from the light sources.
Claim 3
Independent Claim 31 words
The method according to claim2 wherein the step of shielding comprises instructing the person to close their eyes at a point prior to obtaining of an image of the person's face.
Claim 4
Dependent Claim 32 words
The method according to claim 2 wherein the step of shielding is achieved by a baffle placed in a path between the person's eyes and a flashing light source of the apparatus.
Claim 5
Independent Claim 33 words
The method according to any of thepreceding claims wherein the at least two different color images are generated separately from a red wavelength source, a green wavelength source and a blue wavelength source.
Claim 6
Independent Claim 37 words
The method according to any of the preceding claims wherein the at least two different color images are generated by placing different color band pass filters in front of the camera and flashing a white light source.
Claim 7
Independent Claim 44 words
The method according to any of the preceding claims wherein the apparatus further comprises at least one near infrared wavelength light source and the step of generating a near infrared wavelength light image of the body part which information is placed into the program.
Claim 8
Independent Claim 31 words
The method according to any of the preceding claims wherein the apparatus further comprises a monitor screen for displaying the person's body part, the monitor screen being connected to the program.
Claim 9
Independent Claim 34 words
The method according to any of the preceding claims wherein the apparatus further comprises a printer, and the method further comprises delivering through the printer a discount coupon for purchase of the recommended product.
Claim 10
Independent Claim 33 words
A method according to any of the preceding claims further comprising printing an image of the person's body part in schematic mode with areas highlighted to identify need for remedial cosmetic product treatment.
Claim 11
Independent Claim 56 words
An apparatus comprising: (a) a program for storing information; (b) a camera connected to the program; (c) at least one visible wavelength light source associated with the camera for separately generating at least two different color images; and (d) at least one ultraviolet wavelength light source associated with the camera for generating an ultraviolet light image.
Claim 12
Dependent Claim 28 words
The apparatus according to claim 11 further comprising a printer, the program being programmed to print via the printer a discount coupon for purchase of a recommended product.
Claim 13
Dependent Claim 30 words
The apparatus according to claim 11 or claim 12 further comprising a monitor screen for displaying a body part of a person, the monitor screen being connected to the program.
Claim 14
Independent Claim 34 words
The apparatus according to any of claims 11 to 13 wherein the at least two color images are generated separately from a red wavelength source, a green wavelength source and a blue wavelength source.
Claim 15
Independent Claim 20 words
The apparatus according to any of claims 11 to 14 further comprising at least one near infrared wavelength light source.
