    Abstract: A display device is provided. The display device includes a display panel including a pixels; a fingerprint recognition sensor including an image sensor disposed under a first surface of the display panel; and a processor to control the display panel and the fingerprint recognition sensor. A portion of display pixels are configured to emit light in a fingerprint recognition mode. The image sensor includes pixels, at least a portion of the pixels are phase detection pixels. The image sensor generates a fingerprint image signal and a fingerprint phase signal based on reflected light received while the portion of display pixels emit light. The main processor is further configured to perform an anti-spoofing operation or a fingerprint authentication operation based on the fingerprint image signal and the fingerprint phase signal.

    Abstract: A mode switching method and apparatus of a terminal including a camera for acquiring motion information of a user and a plurality of operation modes for power management is provided. The mode switching method includes transitioning, when a motion of a first pattern is detected by the camera, the terminal from an active mode to a standby mode, transitioning, when a motion of a second pattern is detected by the camera, the terminal from the standby mode to an inactive mode, and transitioning, when a first mode switching input is detected in the inactive mode, from the inactive mode to the active mode, wherein the camera acquires the motion information of the user in at least one of the active mode and the standby mode.
