Terminal and method for iris scanning and proximity sensing

摘要

A method of iris scanning and proximity sensing includes: receiving selection information of an operation mode; sensing an iris including emitting light having an amount of light of a first level, and photographing an iris using the emitted light if a selected operation mode is a iris scanning mode; sensing a proximity including emitting light having an amount of light of a second level, and sensing information on whether an object has approached using the emitted light if the selected operation mode is a proximity sensing mode; and recognizing the iris using the photographed iris image, and performing a function according to the sensed information on whether the object has approached, and the first level has a value higher than the value of the second level.

1. A method of iris scanning and proximity sensing in a terminal, the method comprising:
determining a selected operation mode is iris scanning mode or proximity sensing mode at an input unit; when the selected operation mode is an iris scanning mode, performing the operation of sensing the iris, the operation of sensing the iris comprising emitting a first light having an amount of light of a first level, and photographing an iris using the first light; when the selected operation mode is a proximity sensing mode, performing the operation of sensing proximity degree, the operation of sensing the proximity degree comprising emitting a second light having an amount of light of a second level, and sensing proximity information on whether an object has approached using the second light; recognizing the iris, by a controller, using the photographed iris image and performing a function according to the sensed proximity information, and wherein the first level is higher than the second level.
