APPARATUS AND METHOD FOR CAPTURING SKIN TEXTURE BIOMETRIC IN ELECTRONIC DEVICES
First Claim
1. A method for enabling a function on an electronic device comprising a touch input device including a plurality of pixels having a surface for providing radiated energy, and a plurality of photosensors, each of the pixels being associated with a sensor, the method comprising:
- during functional use of the electronic device by a user;
touching skin of the user against a portion of the surface of the touch input device;
sensing that portion of the touch input device that is touched by the user'"'"'s skin;
applying radiant energy toward the skin from only that portion of the touch input device touched by the skin;
collecting radiant energy reflected from the skin by at least a portion of the plurality of photosensors;
converting the collected radiant energy into data; and
enabling the function when the data corresponds to a reference sample.

Abstract
A method is provided for enabling a function on an electronic device (110, 210, 410) comprising a touch input device (112, 116, 212, 218, 312, 424, 432) including a plurality of pixels having a surface (316) for providing radiated energy having one or more spectral bands, and a plurality of photosensors (340), at least one each of the photosensors (340) being incorporated within each of the pixels. The method comprises, during functional (normal) use of the electronic device by a user, sensing (512) a portion of a touch input device (112, 116, 212, 218, 312, 424, 432) touched by the user'"'"'s skin, applying (514) radiant energy to the skin from only that portion of the touch input device (112, 116, 212, 218, 312, 424, 432) touched, and collecting (516), by the plurality of photosensors (340), radiant energy reflected from the skin. The collected radiant energy is converted (624) into data and a function of the electronic device (112, 116, 212, 218, 312, 424, 432) is enabled (530) when the data corresponds to a reference sample.

12. A method for enabling a feature on an electronic device, comprising:
-
sensing skin by a portion of a touch input screen; illuminating the skin with radiated energy emitted from only the portion of the touch input screen; receiving scattered radiation back from the skin; estimating active characteristics from the received scattered radiation; comparing the active characteristics with reference characteristics; and enabling a function of the electronic device if the comparison of the active characteristics and the reference characteristics are within a defined range of values. - View Dependent Claims (13, 14, 15, 16)

17. A method for capturing skin texture characteristics to enable an electronic device, comprising:
-
touching skin of a user of the electronic device against a portion of a touch input display screen, the touch input display screen capable of being illuminated; surreptitiously performing the steps comprising; illuminating the skin from only that portion touched; receiving reflected illumination from the skin by the touch input display; and enabling a function of the electronic device if characteristics of the reflected illumination match stored reference characteristics. - View Dependent Claims (18, 19, 20)
