A low-resolution image is displayed at high resolution and power consumption is reduced. Resolution is made higher by super-resolution processing. Then, display is performed with the luminance of a backlight controlled by local dimming after the super-resolution processing. By controlling the luminance of the backlight, power consumption can be reduced. Further, by performing the local dimming after the super-resolution processing, accurate display can be performed.

The disclosure is related to a method and a system for detecting a video scan type. In the method, a first frame and a second frame are firstly extracted from a video. The scan lines of each frame can be divided into a top field and a bottom field. A first zipper index of the combination of the top field of the first frame and the bottom field of the second frame is obtained. Further, a second zipper index of the combination of the bottom field of the first frame and the top field of the second frame is also obtained. A zipper index difference between the first zipper index and the second zipper index is calculated and is provided to determine the video scan type as an interlaced-scan video or a progressive-scan video.

A data processing system includes a scaler 18 operable to scale a received input data array to provide a scaled output version of the input data array. When it is desired to produce a de-interlaced and scaled output version of an input data array 21, 22, the input data array 21, 22 is provided to the scaler 18, and the scaler 18 scales the input data array 21, 22 so as to simultaneously de-interlace and scale the input data array and to produce a de-interlaced and scaled output version of the input data array.

A multi-vision device can include a first display set configured to display a first split image of an entire image of content according to a progressive scanning method; a second display set disposed on a lower side of the first display set to display a second split image of the entire image; and a control unit configured to scan the second split image on the second display set according to a reverse-progressive scanning method, invert the scanned second split image vertically and display the inverted second split image on the second display set.

A low-resolution image is displayed at higher resolution and afterimages are reduced. Resolution is made higher by super-resolution processing. In this case, the super-resolution processing is performed after frame interpolation processing is performed. Further, in that case, the super-resolution processing is performed using a plurality of processing systems. Therefore, even when frame frequency is made higher, the super-resolution processing can be performed at high speed. Further, since frame rate doubling is performed by the frame interpolation processing, afterimages can be reduced.

Aspects of the present invention relate to a display device, a timing controller, and an image display method. When a frame of an input image signal including an odd-field signal and an even-field signal is received, a timing controller outputs a gate scanning clock (GCK) signal and an output enable (OE) signal in an interlaced scanning manner, to separately scan the odd-field image and the even-field image in the interlaced scanning manner in real time. The interlaced scanning manner is used for the interlaced signal, thereby saving a storage equipped in a converter.
