An image transforming apparatus and method include a linear interpolation block for generating linear interpolation information for a pixel to be interpolated between original pixels of a predetermined image; an edge information generating block for generating edge information and edge location information; 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. Therefore, an image can be transformed into a high-resolution enlarged image with an edge area expressed clearly.
