  • IMAGE INTERPOLATION APPARATUS AND METHOD
    Publication number: 20090154830
    Abstract: The present invention is an interpolation device and method. According to the present invention, a plurality of pixels close to a pixel to be interpolated are sequentially set to a central pixel. When a pixel difference closest to a threshold value among pixel differences between the central pixel and a plurality of pixels around the central pixel belongs to a quasi-edge decision range, an edge interpolation and a bilinear interpolation are mixed to interpolate the pixel to be interpolated. As a result, it is possible to prevent reduction in image quality due to an edge verdict caused by unstable input image signal and perform a stable interpolation operation.
