Abstract
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.
