Abstract:
1. A method of processing image data for display by a display panel of a display device, comprising: receiving main image pixel data representing a main image and side image pixel data representing a side image; using a controller to perform a mapping of the pixel data to signals used to drive the display panel, wherein 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; and performing a compression of the main image pixel data 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, where the compression is performed in advance of or at least partly incorporated into the mapping.
