Abstract: Provided is a display device including a display panel, a power delivery network (PDN), an image controller, and a PDN controller. The display panel may include a plurality of sub-panels. The PDN may be controlled by a control signal, respectively deliver voltages determined by the control signal to the plurality of sub-panels, and generate state information for determining the control signal. The image controller may receive to store frame image data, determine a number of frames to be integrated according to a window size, and integrate the frame image data of frames in the determined number into one image to generate integrated image data. The PDN controller may generate the control signal and a size adjusting signal based on the state information and the integrated image data, provide the generated control signal to the PDN, and may provide the generated size adjusting signal to the image controller. The size adjusting signal may adjust the window size.

Abstract: A high-speed motion estimation method for estimating a motion of a picture at high speed in a high-speed motion estimation apparatus including an integer-times motion estimation unit and a decimal-times motion estimation unit. The integer-times motion estimation unit (1) receives pixel data of a picture for estimation of motion from an external frame memory, (2) stores pixel data of a current region in a current macroblock storage where multiple inputs/outputs are made, (3) stores pixel data of an estimation region in an estimation region macroblock storage of a sharable multiple input/output bank type, and (4) predicts an integer-times motion vector using both stored pixel data. The decimal-times motion estimation unit reads the pixel data of the estimation region from the estimation region macroblock storage which is sharable, and predicts a decimal-times motion vector using the read pixel data of the estimation region and the integer-times motion vector.
