摘要：According to the present invention, it is possible to display an image signal withas a high picture quality as would have been obtained with a solid image pick-up devicehaving color filters arrayed in a mosaic pattern. The image signal obtained from the solidimage pick-up device with a Bayer array of the three primary colors of R, G, and B is

separated by a color separation circuit into R-color, G-color, and B-color signals. Thesecolor signals are attenuated by filters respectively at half a horizontal sampling

frequency in order to suppress the occurrence of moire noise. The G-color filter circuit 8has a narrower attenuation band width than that of the R-color filter circuit and the B-color filter circuit . These color signals thus filtered are adjusted in level at a whitebalance circuit and then mixed by addition at a mixer , thus generating a luminance signal.By narrowing the attenuation band width of the G-color signal, the resolution can be kepthigh while suppressing the occurrence of moire noise.
