Abstract

A graphics device and method for upscaling an input image by adding a plurality of additional pixels. The graphics device includes: a degamma section that performs degamma processing on input RGB data signals in frame units; an RGB-RGBW conversion section that converts the RGB data signals applied from the degamma section into RGBW data signals; an RGB interpolator for generating R, G, and B data signals for each additional pixel from the R, G, and B data signals of any pixel adjacent to the corresponding additional pixel in the image; and an RGB interpolator based on the corresponding additional pixel in the input image W data signals of adjacent pixels to generate a W data signal for each additional pixel W interpolator. The R, G, and B data signals for each additional pixel have the same values ​​as the R, G, and B data signals of any pixel adjacent to the corresponding additional pixel in the input image. The W data signal of the additional pixel is obtained by averaging the W data signals of pixels adjacent to the additional pixel in the input image.
