Abstract: The embodiment is a target tracking method. The method is applicable to a UAV including a visible light camera and an infrared camera, and includes: controlling the visible light camera to perform visual tracking on a target object, and recording first tracking information of the target object in real time; controlling the infrared camera to perform infrared tracking on the target object, and recording second tracking information of the target object in real time; controlling, in a case of determining that the target object is lost in the visible light camera, the visible light camera to re-lock the target object according to the second tracking information and continue to perform visual tracking; or controlling, in a case of determining that the target object is lost in the infrared camera, the infrared camera to re-lock the target object according to the first tracking information and continue to perform infrared tracking.

Abstract: A method of displaying a three-dimensional (“3D”) image, the method includes determining a shutter electrode of an unit part included in a shutter panel as a left-eye electrode and a right-eye electrode, the unit part including ‘n’ shutter electrodes (herein, n is a natural number), selectively driving the left-eye electrode and the right-eye electrode as an opening part based on an image displayed on a display panel to transmit light through the opening part, and providing light transmitted through the opening part with an observer's two eyes through a lens plate, the lens plate including a plurality of lenses.

Abstract: Provided is a display device comprising a display panel having an array of display pixel elements for producing a display output; a viewer detecting system rendering data representing 1) the illumination intensity of a body part of the viewer and 2) another property of the body part; at least one illumination source for providing illumination of a body part of the viewer; and a processor configured to 1) process the data representing the illumination intensity of a body part of the viewer and 2) drive the at least one illumination source dependent on said illumination data to adapt the illumination intensity of a body part of the viewer.
