Abstract

Provided are a method and an apparatus for recognizing a three-dimension object using a light source. The method of recognizing a three-dimension object of a terminal including a display unit for displaying an operation state of the terminal and a shoot unit for receiving an image, includes: receiving a first image by setting first brightness as brightness of the display unit; receiving a second image by setting second brightness as the brightness of the display unit; and recognizing the three-dimension object based on brightness change of a preset part by comparing the second image with the first image. The apparatus and method for recognizing a three-dimension object prevents a security function from being incapacitated using a two-dimension photograph.

Description

technical field [0001] The present invention relates to an apparatus for recognizing a three-dimensional object, and more particularly, to a method and apparatus for recognizing a three-dimensional object using a light source. Background technique [0002] In recent years, the use of portable terminals such as portable tablet PCs has increased. Therefore, demands for security functions of portable terminals have increased. The security function is a function that people other than the owner of the portable terminal cannot use the portable terminal. [0003] According to a password input scheme known in the art, a user can set a password for using the portable terminal. When the power of the portable terminal is turned off and then turned on, or when the portable terminal is switched from a sleep mode to an active state, the portable terminal provides a password input screen. If the user correctly inputs the preset password, the portable terminal becomes a state allowing t...
