Abstract: A video controller, a playback controller and a display system relate to display field. The video controller comprises a plurality of first DVI interfaces, a decoder and a plurality of second DVI interfaces; each of the first DVI interfaces sends an image data stream received to the decoder; the decoder parses preserved control bits in the first image data stream; the decoder sends the image data stream to a second DVI interface corresponding to image position information; the second DVI interface outputs the image data stream. The playback controller comprises an encoder and a plurality of third DVI interfaces. The display system comprises the video controller, a display apparatus and the playback controller.

Abstract: The present invention relates to a hand-written recording device and a hand-written recording method, the hand-written recording device comprising a sensing module for sensing real time location information of the hand-written recording device itself and a processing module for generating a moving track of the hand-written recording device based on the real time location information and generating storable information based on the moving track. Such a hand-written recording device does not have to rely on a bearing surface, which is convenient for the user to record information anytime and anywhere, increases flexibility for the user to record information significantly, and improves the user experience greatly.

Abstract: The present application discloses an image interpolation method for interpolating a pixel and enhancing an edge in an image, comprising detecting an edge position in an image; obtaining edge characteristics associated with the edge position; determining whether an interpolation point is located within an edge region based on the edge characteristics of an array of p×q pixels surrounding the interpolation point, wherein p and q are integers larger than 1; determining edge direction of an interpolation point located within the edge region, wherein the edge direction is normal to gradient direction; classifying the edge direction accordingly to in angle subclasses and n angle classes; wherein each angle class comprises one or more subclasses, m and n are integers, and n?m; selecting a one-dimensional horizontal interpolation kernel based on the angle class; performing a horizontal interpolation using the selected one-dimensional horizontal interpolation kernel; and performing a vertical interpolation using a one

Abstract: There is provided an image interpolation method and an image interpolation apparatus. The image interpolation method comprising: interpolating pixels of a source image with zeros to form an up-sampling image; obtaining a reference interpolation kernel using the up-sampling image; and convolving the pixels of the source image, the reference interpolation kernel and a directional shift coefficient matrix to perform reference kernel interpolation based on directional shift on the source image.
