1. A method for reducing image artifacts in an image that includes a number of pixels each of which includes at least one video information value, the method comprising: generating a plurality of filter coefficients for at least some of the pixels of the image, on the basis of which the video information values of the pixels can be reconstructed; performing artifact detection to detect artifact regions within the image; modifying at least some filter coefficients of those pixels that lie within the artifact regions to generate modified filter coefficients; and synthesizing the video information values using the filter coefficients, the modified filter coefficients being employed for the synthesis for pixels lying within the artifact regions.
