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 exposure time determination method for image sensing operation includes: providing a first stage exposure condition which includes a first exposure time; sensing an image according to the first stage exposure condition to generate a first histogram which has a first histogram brightness maximum, a first histogram brightness minimum, and a first histogram width; increasing or decreasing the first exposure time to a second exposure time as a second stage exposure condition, and sensing the image according to the second stage exposure condition to generate a second histogram which has a second histogram brightness maximum, a second histogram brightness minimum, and a second histogram width; comparing the first histogram width with the second histogram width to generate a comparison result, and determining a third exposure time to be a third stage exposure condition according to the comparison result; and sensing the image according to the third stage exposure condition.
