Abstract:
1. An image display apparatus for displaying an image on an image display panel having a plurality of pixels, the plurality of pixels each including a plurality of subpixels of different colors, the apparatus comprising: an interpolation operator operable to interpolate consecutive sampling values of pieces of input color data of each of the plurality of subpixels supplied to drive the image display panel to thereby correct phases of the pieces of input color data of each of the plurality of subpixels based on positions of the plurality of subpixels in each pixel and output pieces of output color data; an area detector operable to detect a specific area from the image displayed on the image display panel by processing the pieces of input color data of each of the plurality of subpixels or the pieces of output color data; and a correction unit operable to compute and output weighted averages of the pieces of input color data of each of the plurality of subpixels and the pieces of output color data on the basis of a detection result obtained by the area detector; wherein the specific area is an edge portion, a portion where a luminance level gradually changes, or a repeated-pattern portion where a spatial frequency is high.
