Methods, and program storage devices, for performing model-based optical lithography corrections by partitioning a cell array layout, having a plurality of polygons thereon, into a plurality of cells covering the layout. This layout is representative of a desired design data hierarchy. A density map is then generated corresponding to interactions between the polygons and plurality of cells, and then the densities within each cell are convolved. An interaction map is formed using the convolved densities, followed by truncating the interaction map to form a map of truncated cells. Substantially identical groupings of the truncated cells are then segregated respectively into differing ones of a plurality of buckets, whereby each of these buckets comprise a single set of identical groupings of truncated cells. A hierarchal arrangement is generated using these buckets, and the desired design data hierarchy enforced using the hierarchal arrangement to ultimately correct for optical lithography.

An image display apparatus is provided that avoids discontinuity in a high luminance and gradation range and is capable of displaying gradations where differences in sense of luminance change at equal intervals from an intermediate gradation range to the maximum value of the gradations. A gradation/light emission luminance converter 104 converts the gradation of an input image into data corresponding to a luminance to be displayed by a video light emitter 107 using predetermined conversion characteristics. In an intermediate gradation range, the common logarithms of the luminances to be displayed by the video light emitter 107 have a proportional relation to the gradations. In the high luminance and gradation range, the relation gradually deviates from the proportional relation; the nearer the gradation approaches the maximum value thereof, the larger the variation quantity of the common logarithm of the luminance to be assigned to an increment of the gradations becomes.
