Apparatus for inputting biometrical feature

An electronic equipment comprising:na 1-dimensional or quasi 1-dimensional image sensor; anda finger sliding guide having a gap over an effective pixel unit of said image sensor and configured to keep a finger not to contact with said image sensor,wherein a height of the gap is 10 μm or more and 200 μm or less.

A biometrical feature inputting apparatus comprising:na 1-dimensional or quasi 1-dimensional image sensor;a finger sliding guide configured to keep a finger not to contact with an effective pixel unit of said image sensor;an upper light source provided for a rear of the finger and configured to emit a light for a blood vessel image; andan image processing section configured to sequentially and alternately generate first 1-dimensional or quasi 1-dimensional partial images obtained by imaging emission light that is scattered inside the finger and then emitted from a skin surface of the finger, and second 1-dimensional or quasi 1-dimensional partial images obtained by imaging emission light that is emitted from said upper light source toward the finger, propagated through the finger and emitted from the skin surface of the finger, by said image sensor during relative motion thereof, to link said first partial images to a first image and said second partial images to a second image, and to extract a blood vessel image as a difference between the first image and the second image.
