Patent ID: 7623141

Claim:
A method of rendering sampled data of an image on a display panel substantially comprising an arrangement of sub-pixel elements in at least two primary colors; the method comprising: receiving the sampled data comprising a plurality of first data values, each of the first data values indicating a value for one color in the image; for each of a subset of sampled data indicating a region of the image, generating a gamma-adjusted data value for each first data value in the subset using an average of said first data value and at least one other first data value in the subset; for each of a subset of gamma-adjusted data values, performing a sub-pixel rendering operation using the subset of gamma-adjusted data values and the subset of first data values to produce an output data value for one of the sub-pixel elements on the display panel; a plurality of output data values collectively forming sub-pixel rendered image data indicating an output image; and outputting said sub-pixel rendered image data for rendering on the display panel.
