Abstract:
1. A character display apparatus, comprising: a display device comprising a plurality of pixels; and a control section for controlling the display device, wherein each of the plurality of pixels comprises a plurality of sub-pixels arranged in a predetermined direction, and at least one of a plurality of color elements is assigned to each of the plurality of sub-pixel; the control section determines at least one sub-pixel, to which a basic portion indicating a skeleton of a character is assigned, among the plurality of sub-pixels in the display device, based on character shape data indicating character shapes; a first pixel of the plurality of pixels comprises a plurality of first sub-pixels; at least one pixel neighboring the first pixel comprises a plurality of second sub-pixels; the control section determines an arrangement pattern containing a plurality of elements, wherein a value of each of the plurality of elements is determined depending on whether or not the basic portion is assigned to a corresponding sub-pixel of the plurality of the first sub-pixels and the plurality of the second sub-pixels; and the control section introduces a predetermined change into the arrangement pattern, the predetermined change including one of replacement of a position of the basic portions and duplication of the basic portion, and determines a luminance level of only the first pixel based on the changed arrangement pattern, wherein the luminance level of the first pixel based on the changed arrangement pattern is determined using a stored table indicating a predetermined correspondence between arrangement patterns of sub-pixels and luminance levels of sub-pixels arranged in a certain direction, which is one of the same as the predetermined direction and different from the predetermined direction, and the correspondence indicated by the stored table is determined using a predetermined correction pattern of color element levels of sub-pixels neighboring a sub-pixel corresponding to the basic portion.
