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.

Optical identification method

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.

Exposure time determination method for image sensing operation

A fingerprint detection apparatus, a mobile device using the same and a manufacturing method thereof are provided. The fingerprint detection apparatus comprises an image sensing integrated circuit and a spatial filter disposed on the image sensing integrated circuit. The spatial filter has adjacent light tunnels for restricting an incident angle of light to the image sensing integrated circuit to prevent scattered light from entering the image sensing integrated circuit.
