Currently, Y, Cb, Cr 4:2:0 system is widely used as the color format for the video system. We have proposed the frame sequential system as an alternative method which has one color plane in a frame. In this system, the conversion to usual RGB requires a motion compensated color interpolation. However, it is not easy in the case of high saturation color images, because of its difference between color planes. To avoid this problem, we propose the new color format which has dependent colors. The primary colors (RGB) are changed to pastel colors. The conversion from RGB to pastel colors is realized by the color matrix. Re-conversion is also possible by using the inverse matrix. To address the conversion to RGB, basic block matching is used in motion estimation. To avoid incorrect motion vectors, the antierror mechanism are strengthened. Finally, the performance of the pastel colored frame sequential and 4:2:0 are compared. From experimental results, the converted RGB pictures have higher PSNR than 4:2:0.
