Abstract:
1. A method of processing image data for display by a display panel of a display device, wherein the display device comprises pixels all having substantially the same angular transmission properties, the method comprising: receiving main image pixel data representing a main image and side image pixel data representing a side image; in a first processing step, performing 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; in a second processing step, processing the received side image pixel data in order to emphasise at least one feature of the side image which might otherwise be perceived by a viewer as being de-emphasised in the side image displayed off axis as a result of the first processing step; and in a third processing step, spatially resampling the side image in order to provide the required number of pixels in the correct aspect ratio for the first processing step.
