Abstract

Den foreliggende oppfinnelse tilveiebringer et optisk system som er virksomt for å eliminere parallakseforvrengning i et oppfanget bilde. Særlig eliminerer anordningen parallakseforvrengning i et håndflateavtrykksbilde. Anordningen innbefatter et prisme som har en mottagende overflate og en objektoverflate. En håndflate anbringes på den mottagende overflaten og et lys belyser den monagende overflaten slik at et bilde som er representativt for håndflaten forplantes fra objektoverflaten. Det forplantede bildet irmbefatter et flertall av segmenter. En linse forstørrer selektivt hvert av segmentene med en forskjellig størrelse for å skape et flertall av forstørrede segmenter som har lik lengde. Et bilderegistrerende medium oppfanger så de forstørrede segmenter. Oppfinnelsen Ulveiebringer også en sylindrisk anordning som er betjenbar for å oppfange bildet av håndflaten, der håndflaten kan rulles over en gjennomsiktig sylinder og reflektert lys oppfanges av et registreringsmedium som er representativt for håndflateavtrykket.The present invention provides an optical system that is effective in eliminating parallax distortion in a captured image. In particular, the device eliminates parallel distortion in a palmprint image. The device includes a prism having a receiving surface and an object surface. A palm is placed on the receiving surface and a light illuminates the monoagric surface so that an image representative of the palm is propagated from the object surface. The propagated image includes a plurality of segments. A lens selectively enlarges each of the different sized segments to create a plurality of enlarged segments of equal length. An image recording medium then captures the enlarged segments. The invention also provides a cylindrical device operable to capture the image of the palm, where the palm can be rolled over a transparent cylinder and reflected light is captured by a recording medium representative of the palmprint.
