    摘要： A method for rendering input data into target data includes: applying a pattern detecting window to the input data about an input pixel to detect a green light emitting pattern within the window; determining whether the detected green light emitting pattern belongs to a threshold pattern in which at least two green subpixels that are contiguously arranged emit light; and rendering the target data for a red or blue target subpixel having a first color by: applying a first filter to the input data of the first color red or blue input subpixels that are near the input pixel when the detected green light emitting pattern does not belong to the threshold pattern; and applying a second filter that is different from the first filter to the input data of the first color red or blue input subpixels when the detected green light emitting pattern belongs to the threshold pattern.

    摘要： Provided is an apparatus for improving the sharpness of an image. The apparatus includes an edge detector, an effective edge judging unit, an effective edge classifying unit, an isolated edge judging unit, and a 2-D HPF applying unit. The edge detector calculates an edge value using brightness relation with neighboring pixels with respect to each of pixels of an input image. The effective edge judging unit determines effective edge pixels. The effective edge classifying unit determines weak edge pixels and strong edge pixels. The isolated edge judging unit judges an isolated edge pixel included in an isolated edge. The 2-D HPF applying unit applies a first 2-D HPF to the weak edge pixels, and applies a second 2-D HPF to the strong edge pixels to generate edge strengthening values. The edge strengthening value applying unit adds the edge strengthening values to brightness values of the respective pixels of the input image.
