Abstract From the Canadian patent

A biometrical feature inputting apparatus includes a 1-dimensional or quasi 1-dimensional image sensor. When a finger and the image sensor are relatively slid, a finger sliding guide keeps a finger and an effective pixel unit of the image sensor to a constant distance without any contact between them. An image processing section sequentially generates partial images by imaging emission light that is scattered inside the finger and then emitted from a skin surface of the finger by the image sensor during the relative motion of the finger and the image sensor and link the partial images to an image.

Why it's free to use

  • Filed November 15, 2005 and granted August 14, 2012. A Canadian patent filed from October 1, 1989 lasts 20 years from filing, so its term ended November 15, 2025.
  • Certificates of supplementary protection extend only drug patents, and it isn't classified as one.
  • We check Canadian rights only. A patent in its family in another country could still be in force: check its family on Google Patents.
