Abstract: A method and apparatus for authenticating a user using a vein pattern are provided that project a near infrared (NIR) ray toward a skin of the user using a light emitting diode (LED), where the user is adjacent to a terminal including the LED. An image sensor receives a light reflected by the skin, generates a vein pattern of the skin based on an image generated using the received light, and authenticates the user as a registered user of a pre-stored vein pattern when the generated vein pattern matches the pre-stored vein pattern.

Abstract: According to one example embodiment, an image sensor is configured to operate in a plurality of operation modes. The image sensor includes a pixel array including unit pixels configured to generate an analog image signal from incident light, a readout circuit configured to generate a digital image signal by converting the analog image signal, and a control module configured to generate control signals for controlling operations of the pixel array and the readout circuit according to an operation mode of the image sensor. A first power voltage for driving the image sensor when the operation mode of the image sensor is an image recognition mode for recognizing a body of a user of the image sensor, is lower than a second power voltage for driving the image sensor when the operation mode of the image sensor is an image capture mode for capturing images by the user.
