<p>PURPOSE:To reproduce two color difference signals in an excellent color and to implement picture reproduction with high resolution by arranging Y picture elements in an offset at a period of basic picture element and arranging offset structure to RGB at the basic sampling period and at a period thrice the basic sampling period. CONSTITUTION:Y picture elements are arranged in a checkered pattern the same as the Bayer arrangement and sampled with high resolution. Offset sampling structure is adopted also for RGB. At first, a signal read from a CCD 1 is AD-converted by an A/D converter 12 and fed to respective processing blocks of YRGB by a color separator 22. A picture element corresponding to a part with no information is interpolated by an interpolation filter 14 to be a final Y signal. Similarly, the RGB signal is interpolated by the interpolation filter. The RGB signal passes through the filter above and is linearly converted into final R-Y, B-Y signals by a matrix computing element 21.</p> |
