Abstract: Provided is a method, performed by a device, of processing an image, the method including tracking a movement of a user wearing the device and generating movement information of the user, the movement information being about a movement occurring between a previous time when a first image was rendered and a current time when a second image is rendered; selecting at least one pixel from among a plurality of pixels comprised in the first image, based on the generated movement information and a location of a target pixel comprised in the second image; and changing a value of the target pixel by blending a value of the selected at least one pixel with the value of the target pixel according to a preset weight.

Abstract: A display device is provided. The display device includes: a graphic processing unit rendering strokes; a display displaying an image including the rendered strokes; and a processor identifying a redraw region when a redraw event occurs on the image, and providing rendering information for rendering strokes included in the redraw region to the graphic processing unit, wherein the graphic processing unit renders the strokes included in the redraw region using point primitives on the basis of the rendering information.

Abstract: Provided are an image processing apparatus and method for decreasing an amount of power consumed to display an image. The image processing apparatus includes: an input interface configured to input image data; at least one processor configured to obtain an output pixel value by adjusting at least one selected from luminance, resolution, and precision regarding a portion of the image data; and an output interface configured to output image data including the obtained output pixel value.
