Publication number: 20100141674Abstract: The disclosed invention provides a display device for performing a gradation display, using a plurality of subframes of image into which one frame of image is divided, and a display method that reduces dynamic false contour noises occurring when the image is displayed and is suitable for plasma display panels and the like. Dynamic false contour noise reduction is performed by detecting luminance on/off state change (carry up/carry down) in a region where a smooth tone level change occurs and interchanging the tone values of pixels in the region. The reduction processing is controlled, based on an amount of motion of an original image and a display load ratio, so that dynamic false contour noise reduction is performed favorably. By carrying out different ways of processing for each frame, noise reduction in the time domain is performed.Type: ApplicationFiled: December 1, 2009Publication date: June 10, 2010Applicant: HITACHI CONSUMER ELECTRONICS CO., LTD.Inventors: Takatoshi OHARA, Masanori TAKEUCHI, Hiroyuki NITTA, Yasuhiro AKIYAMA
