In a method of chrominance interpolation to obtain at least one interpolated chrominance sample (c2, c3, c4) between first (c1) and second (c5) existing chrominance samples, a corresponding relative luminance step is determined for a chrominance sample (c2, c3, c4) to be interpolated, the first (c1) and second (c5) existing chrominance samples are subtracted to obtain a chrominance step, and the chrominance samples (c2, c3, c4) to be interpoled are calculated by adding to the first existing chrominance sample (c1), a product of the chrominance step and the corresponding relative luminance step. The method is advantageously used in multimedia terminals. |
