PROBLEM TO BE SOLVED: To provide a recursive filter system for a video image including a memory to store a first image of a stored pixel S(x, y). SOLUTION: In a recursive filter system 10, weighted values W(x, y) of luminance and chrominance of the stored pixel S(x, y) are obtained by summing weighted values B(x, y), S(x, y) of luminance and chrominance of the pixel and neighboring pixels. A first proportional parameter A(x, y) is generated for the stored pixel based on a modular sum of differences between luminance and chrominance of the stored pixel and of surrounding pixels. The first proportional parameter A(x, y) is used to generate a weighted pixel M(x, y) from a proportion of the stored pixel S(x, y) and a complementary proportion of the weighted value W(x, y).
