Complementary Field Offset Sampled-Scanning for GRB Video Elements

We propose a new scanning method which is comparable to progressive scanning. The method improves the resolution of video equipment with GRB three elements. We position both red (R) and blue (B) pixels diagonally offset at a half the pixel pitch from green (G) pixels, and alternating the position of G pixels and both the position of R and B pixels for each field. The Nyquist frequency in both horizontal and vertical directions of the video equipment is doubled compared to that of each field. The method also eliminates artifacts caused by interlace scanning.
