An optical identification method for sensing a physiological feature, includes: projecting light to a physiological portion for generating reflection light from the physiological portion; receiving the reflection light, to generate an image; generating slant pattern information according to the image; transforming the slant pattern information into a pattern identification matrix; and determining the physiological feature according to the pattern identification matrix.

Optical identification method and optical identification system

An optical identification method, includes: projecting light on a finger to generate reflected light from the finger; receiving the reflected light by a pixel sensing array to obtain a plurality of finger images; and determining whether the finger images present a liveness characteristic, according to a required exposure time or average brightness of the finger images obtained by the pixel sensing array. When the finger images present the liveness characteristic, the optical identification method further includes: determining identification information according to the finger images; or when the finger images do not present the liveness characteristic, the optical identification method further includes: not determining identification information according to the finger images, and optionally, stopping the pixel sensing array from obtaining a subsequent finger image.
