摘要： A method of processing image data for display by a display panel of a display device. The method comprises receiving main image pixel data representing a main image and side image pixel data representing a side image, and performing a mapping of the pixel data to signals used to drive the display panel. The mapping is arranged to produce an average on-axis luminance which is dependent mainly on the main image pixel data and an average off-axis luminance which is dependent at least to some extent on the side image pixel data. A compression of the main image pixel data is performed in advance of or at least partly incorporated into the mapping, the compression being performed at least partly in dependence upon the main image pixel data and at least partly in dependence upon how the off-axis luminance varies with pixel data input to the mapping.

摘要： A method of performing spatio-temporal up-scaling includes receiving an input video having a sequence of input frames, analyzing the input video to estimate motion vectors associated with the sequence of input frames, and determining corresponding motion compensation errors associated with the motion vectors. The method further includes determining an extent to which computational resources are to be respectively allocated to spatially up-scaling the sequence of input frames and temporally up-scaling the sequence of input frames, based on the estimated motion vectors and corresponding motion compensation errors. In addition, the method includes spatio-temporally up-scaling the sequence of input frames based on the determined extent.

摘要： A method is provided for performing robust frame rate conversion of video data to a higher frame rate. A metric is formed (16) as a function of motion compensation error normalised by a measure of image content, such as image texture (10, 11). The metric is then compared with thresholds (17, 18) to determine whether conversion will be based on motion compensated interpolation or frame repetition. If the metric falls between thresholds, the previously selected mode may be repeated.
