| 1. A method of selectively providing spatial sampling filtering in a display system that processes image data signals representing
both image areas that are sub-pixel rendered areas and image areas that are non-sub-pixel rendered areas, wherein the selectively
provided spatial sampling filtering transforms the image data signals into spatially filtered signals, the method being implemented
by the display system and comprising:
detecting sub-pixel rendered areas of the image data signals by testing portions of the image data signals for satisfaction
of a first condition, the first condition being satisfied when for a first pixel within one of the tested portions, a first
color luminance defined by a corresponding portion of the image data signal for a first to-be-displayed sub-pixel-emitted
color of the first pixel is not equal to a second color luminance defined by a corresponding portion of the image data signal
for a second to-be-displayed, different and sub-pixel-emitted color of the first pixel and further when said second color
luminances as averaged out due to respective sub-pixel emissons of the first pixel and successively adjacent other pixels
in a predefined neighborhood of the given first pixel are substantially equal to one another;
turning on, within the display system, a first set of spatial sampling filters for corresponding said subpixel rendered areas
in response to the detecting of satisfaction of the first condition; and
turning on a second set of different spatial sapling filters for corresponding non-sub-pixel rendered areas in response to
failure of the detection of the satisfaction of the first condition.
