    摘要: The present invention provides a method and a system for video stabilization in real time. The method comprises the steps of: estimating an optical flow from an previous image, Ii, to a current image, Ii+1; determining an Euclidean transformation, Fi, from the previous image, Ii to the current image, Ii+1, wherein the Euclidean transformation, Fi, comprises a product of rotation, Ri, and scaling, si, and translation, Ti; and transforming the current image, Ii+1, by applying the inverse of the Euclidean transformation, Fi, to the current image, Ii+1 in order to obtain stabilization. The transformation of the current image, Ii+1, is restricted by using Euclidean matrices Ai and Bi, wherein: Ai is used to store absolute frame transformation relative world frame coordinates, A0 is the identity matrix and Ai+1 is equal to AiFi−1 for i≧0 and Bi is used to store visualization window coordinate transformation.

    摘要: In a DVD playback mode only, the first type interface is disabled and a DVD driver unit having a hardware DVD decoder connected to a DVD reader unit arranged to read video data from a DVD inserted therein is powered on. In the described embodiment, the DVD decoder unit is also connected to the display screen by way of a second type interface is powered on. The video data is read from the DVD by the DVD reader unit and sent by the DVD reader unit to the hardware DVD decoder unit which then decodes the video data before passing it directly to a timing controller unit coupled to the display screen by way of the second type interface. The timing controller unit converts the video data at a native resolution to a display screen resolution that is then displayed on the display screen.

    摘要: In a liquid crystal display (LCD) panel based display, a method of dynamically selecting either frame rate conversion (FRC) or pixel voltage overdrive is disclosed. The method is carried out by performing the following operations. A video vertical refresh rate of an incoming video data stream is determined and based upon the determining, only one video data stream conditioning protocol from a number of available video data stream conditioning protocols is selected. The selected video data stream condition protocol is then applied to the video data stream.

    摘要: A display unit designed to be scanned within a narrow horizontal scanning range irrespective of the frequency at which the horizontal lines of an image are received. If the horizontal line frequency of the received display signal does not fall within the narrow horizontal scanning range, the image frames in the display signal are scaled at least vertically such that the number of horizontal lines in each scaled image frame times the frame rate falls within the horizontal scanning range. As a result, the images can be scanned within the horizontal range for which a display unit is designed for. The scaling can be performed without using a frame buffer as the frame rate (at which the images are encoded in a display signal) equals the scanning rate.
