Abstract:
A device for analyzing the surface structure of an object, the device comprising a touchable Lambertian light diffusing surface that covers a cavity containing a light source and an image sensor. The image detector senses the contact of the outer Lambertian surface of the device by a contacting object, for example a finger-tip, by means of light from the light source reflecting back to the image detector. At the same time, ambient light from objects external to the device is diffusely scattered by the Lambertian surface as it enters the cavity and does not affect the ability of the image detector to clearly determine the surface structure of the contacting object. Thus, for example, the surface contours of a fingerprint may be determined with a high signal-to-noise ratio.

Claim (Index 4):
An image processing device, comprising:\n a) a cavity covered by a semi-transparent plate having a Lambertian outer surface and a transparent inner surface; b) a source of illumination within said cavity wherein said illumination is directed at said transparent inner surface; c) wherein said image sensor is sensitive to ambient illumination directed at said Lambertian outer surface from objects external to said device; d) an image sensor within said cavity, said image sensor being sensitive to said illumination from both said source of illumination within said cavity and said ambient illumination from objects external to said cavity; e) a memory cache for storing images created using said image processing device; f) wherein said image processing device is configured to compare images and determining differences between them; whereby\n said image processing device is configured such that when an object contacts said Lambertian surface said image sensor is presented with two forms of illumination, illumination from said external objects which is diffusely scattered from said Lambertian surface and reaches said image sensor in a non-identifiable form and illumination from said source of illumination within said cavity that is reflected back at said sensor from said object contacting said Lambertian surface from below, which is bright and less scattered illumination and reaches said image sensor in an identifiable form; whereby \n said reflected image is highly resolved and clearly identifiable by said image sensor and said ambient illumination does not adversely affect identifiability of said object and enables the creation of comparable images.
