Abstract: An apparatus and method for controlling a virtual monitor in an augmented reality display system are provided. The method for controlling a virtual monitor in an augmented reality display system, including a camera for photographing an image for determining a location of the virtual monitor and for photographing an image of a user's finger, and a graphic device including window images, includes parallel-processing the image for determining a location of the virtual monitor and the window images and mapping the window images to a set location to create the virtual monitor, extracting a finger tip from the image of the user's finger, stencil-buffering an image of the finger tip not to render the image of the finger in the virtual monitor, determining whether the finger tip collides with the stencil-buffered virtual monitor, and controlling an operation of the virtual monitor according to the determination of the finger tip collision.

Abstract: An electronic device is provided. The electronic device includes a display, a processor electrically connected with the display, and a memory electrically connected with the processor. The memory includes instructions, which, when executed by the processor, cause the processor to change a first image such that the first image including a first amount of data is changed to include a second amount of data that is less than the first amount of data, extract at least one dominant color of at least one partial area of the changed first image, perform a gradient in the at least one partial area of the changed first image based on the extracted at least one dominant color, and control the display to display a second image including the at least one partial area to which the gradient is applied on at least one part of the display.
