A digital device including a camera unit; a display unit; and a controller configured to in response to a request to execute a first application on the digital device having a first security authentication level, control the camera unit to capture face image data of a target and perform a first authentication process by comparing the captured face image data with prestored face image data; and in response to a request to execute a second application on the digital device having a second security authentication level more secure than the first authentication level, control the camera unit to capture vein image data of a particular body part of the target, and perform the first authentication process and a second authentication process by comparing the captured vein image data with prestored vein image data.

Digital device and biometric authentication method therein

Disclosed is a foot vein authentication device comprising: a body part having a front surface and a rear surface and on which the foot of a user is placed on the front surface; a sensor unit arranged on any one area of the body part and formed so as to detect a vein pattern on the inside of the foot of the user; and a control unit for carrying out a user authentication procedure by comparing the vein pattern received from the sensor unit, with the pre-stored vein pattern of the user, wherein the sensor unit comprises: a light source unit for emitting infrared rays at the inside of the foot of the user; and an image acquisition unit for acquiring, as an image, the vein pattern on the inside of the foot of the user, at which the infrared rays are emitted, so as to transmit the same to the control unit.

Foot vein authentication device

A biometric authentication device including an infrared luminescent unit configured to emit infrared light with an infrared wavelength; a depth sensing unit configured to receive the infrared light reflected on a vein of an object placed within a preset distance of the depth sensing unit; a controller configured to control the depth sensing unit to obtain a first vein image of a first object and calculate a first distance value corresponding to a first distance between the depth sensing unit and the first object, and store the first vein image and the first distance value in a memory as registration information.

Biometric authentication device

A digital device including a camera unit; and a controller configured to in response to a request to execute a first application on the digital device having a first security authentication level, control the camera unit to capture first vein image data at a first depth of a particular body part of a target and perform a first authentication process by comparing the captured first vein image data with prestored first vein image data, and in response to a request to execute a second application on the digital device having a second security authentication level more secure than the first authentication level, control the camera unit to capture second vein image data at a second depth of the particular body part of the target and perform the first authentication process and a second authentication process by comparing the captured second vein image data with prestored second vein image data.

Disclosed are a wearable device and controlling method thereof. The present invention includes a flexible surface light source, a photo panel located on a top surface of the flexible surface light source, and a controller coupled with the flexible surface light source and the photo panel. The controller is configured to detect a first biometric image by controlling the flexible surface light source and identify a user by comparing the detected first biometric image to a second biometric image previously saved in a memory.

Wearable device and controlling method thereof

The present invention relates to a mobile terminal capable of a new type of user input, comprising: a backside input unit including a plurality of buttons and exposed to the backside of the mobile terminal; a memory for storing relationships between combinations of the plurality of buttons and control instructions of the mobile terminal and biometric information; a sensor unit, arranged on the backside of the mobile terminal and adjacent to the backside input unit, for sensing a user's bio signal; and a control unit for, upon receiving a user input in accordance with a particular combination of the plurality of buttons, controlling the sensor unit to sense the user's bio signal, and authenticating the user using the sensed bio signal and the stored biometric information.

Mobile terminal and method for controlling same

An apparatus and method for measuring 3-dimensional (3D) interocular crosstalk is disclosed. A light sensor detects luminance of a stereoscopic image displayed in a display and outputs a luminance value indicating the detected luminance. A controller calculates 3D interocular crosstalk based on a gray difference and a residual luminance ratio.

Apparatus and method for measuring 3-dimensional interocular crosstalk

An image display device, a 3D viewing device, and a method for operating the same are provided. The method includes receiving a synchronization signal from an image display device, alternately opening a left glass and a right glass according to the synchronization signal, and simultaneously opening the left glass and the right glass in a left-eye image display period or a right-eye image display period of a 3D image displayed on the image display device when a period of the synchronization signal has changed. This ensures that a user reliably (or correctly) views 3D or 2D images using the 3D viewing device.
