Claim Text:
1. A method of processing image data for display on a display device, the display device comprising a multi-primary image display panel, the method comprising: receiving image data constituting an image for display on the image display panel; in a first mode, determining signal voltages to be applied to sub-pixels of the image display panel from the received image data and from a secondary data value for the pixel thereby to generate luminance variations perceivable at a first viewing position but substantially not perceivable at a second viewing position, and in the first mode, determining signal voltages to be applied to sub-pixels of the image display panel such that the signal voltage for a first sub-pixel of a first pixel of the image display panel is changed in an opposite direction to the signal voltage for a second sub-pixel of the first pixel.
