COLOR IMAGING DEVICE

摘要

It is possible to reduce the occurrence of false colors, achieve higher resolution, and simplify a following process in comparison to the usual random arrangement. A color filter arrangement contains a basic arrangement pattern (P1, pattern delimited by bold border) comprising a square arrangement pattern corresponding to 3x3 pixels. This basic arrangement pattern (P1) is repeated in the horizontal and vertical directions. In the basic arrangement pattern (P1), the G filter, which is the luminance-based pixel, is positioned in the four corners and in the center, or in other words, so as to form two diagonal lines. As a result, the G filter is positioned within each line in the horizontal, vertical, and diagonal directions in the color filter arrangement, and the color filter arrangement contains a square arrangement corresponding to 2x2 pixels comprising the G filter. In addition, the proportion of number of G pixels, which contribute the most for acquisition of a luminance signal of the basic arrangement pattern (P1), is greater than the respective proportions of the number of pixels for the other colors, namely the R pixels and B pixels; hence, the proportion is effective for simultaneous processing.
