PROBLEM TO BE SOLVED: To reduce the occurrence of an artifact in a digital image. SOLUTION: An example includes a system and a method provided with a correlation prevention space-time dither pattern which displays high-pass properties in a space region and time region. The method of forming these patterns includes occurrence of a series of dither tile for a number of image property channels and time regions. In the illustrated example, for each of the three RGB color channels, different dither patterns 50, 52 and 54 can be occurred, and for a series of time frame 58, 60, 62 and 64, three tile set 58 can be occurred. In this example the multi dimensional array of a tile occurs. In another example, chrominance and luminance channels in varying number are used, and even in a serial frame in the time region, a variable pattern can be used. COPYRIGHT: (C)2005,JPO&NCIPI
