Abstract:
1. An apparatus for transforming an image, comprising: a linear interpolation block for generating linear interpolation information for an interpolation pixel to be interpolated between original pixels of a predetermined image; an edge information generating block for generating edge information which represents a pixel value of a pixel for indicating an edge and generating edge location information for indicating a location of an edge area of the image using two threshold values, within each of blocks consisting of the original pixel and interpolation pixel, respectively; a weight determining block for determining a weight for the linear interpolation information and the edge information of the interpolation pixel based on the edge location information; an interpolation information generating block for determining a pixel value of the interpolation pixel by reflecting the weight to the edge information and the linear interpolation information; and an interpolating block for generating the interpolation pixel based on the pixel value determined in the interpolation information generating block.
