摘要： Provided are a lighting system, a backlight unit and a 3D image display apparatus including the backlight unit. The backlight unit includes: a lighting system configured to selectively output collimated light and diverging light, a diffraction device, and a light guide plate configured to guide the collimated light and the diverging light from the lighting system to the diffraction device. An exit direction of the collimated light from the diffraction device depends on at least one of an angle of incidence of the collimated light and the wavelength of the collimated light.

摘要： A method of recognizing a fingerprint includes generating, by using a fingerprint sensor, an input fingerprint image that is to be used when a fingerprint verification mode is executed; obtaining, from a memory, a registered fingerprint image that is generated from a finger image captured by a camera and stored in the memory prior to the generating the input fingerprint image; determining, from among partial regions of a registered fingerprint image that is obtained, a partial region of the registered fingerprint image, which is superimposed on the input fingerprint image, as a registered superimposed image; converting the registered superimposed image such that a first histogram of the registered superimposed image corresponds to a second histogram of the input fingerprint image; and determining, by comparing the registered superimposed image, which is converted, with the input fingerprint image, whether the input fingerprint image is verified.
