Patent number: 8320701Abstract: A smoothing filter generates a smoothed picture by smoothing a brightness component of an input picture. An adjustment filter generates an adjusted picture by applying a filter to an area of the input picture. The filter has the same characteristic as the smoothing filter.

Patent number: 7663651Abstract: An image has pixels arranged in ((M lines)×(N columns)) each pixel having color information. A display has elements arranged in ((P lines)×(Q columns), 1<P<M, 1<Q<N). The image is separated into a first component and a second component based on a threshold. The first component has a spatial frequency not lower than the threshold. The second component has a spatial frequency lower than the threshold. The threshold is a ratio of the number of the elements to the number of the pixels. A plurality of first display components is generated from the first component by filter processing using a plurality of filters. A second display component is generated from the second component by filter processing. A plurality of sub-field images is generated by composing each of the plurality of first display components with the second display component. Each element of the display is driven using the color information of a pixel corresponding to the element in pixels of each of the plurality of sub-field images.Type: GrantFiled: July 17, 2006Date of Patent: February 16, 2010Assignee: Kabushiki Kaisha ToshibaInventors: Goh Itoh, Kazuyasu Ohwaki
