摘要： The generation of a false color is prevented. In a pixel mixture block, pixels of the same color are mixed. For example, red pixels are mixed to obtain a red mixed pixel and blue pixels are mixed to obtain a blue mixed pixel. Green pixels in an odd-numbered row and pixels in an even-numbered row are separately mixed to obtain a green mixed pixel and a green mixed pixel. A correlation direction in a partial color image 1 is detected from these mixed pixels. Interpolation pixels are generated from the mixed pixels according to the correlation direction such that a false color is not generated.

摘要： According to an aspect of the present invention, the first filters, which correspond to the two or more first colors that contribute to obtaining a brightness signal more than the second colors, are disposed within each pixel line in first direction to the fourth direction of the color filter arrangement, and it is configured so that the ratio of the number of pixels of the first colors corresponding to the first filters is larger than the ratio of the number of pixels of each color of the second colors corresponding to the second filters of two or more colors other than the first colors. Accordingly, the degree of reproducibility of the synchronization processing in a high-frequency wave area can be increased and the aliasing can be suppressed.

摘要： A color filter array includes a basic array pattern constituted by a square array pattern that corresponds to 5×5 pixels, and the basic array pattern is repeatedly arranged in horizontal and vertical directions. In the basic array pattern, the G filters that are brightness system pixels are arranged on at least the both diagonal lines. As a result, the G filter is arranged in each line of horizontal, vertical, and diagonal directions of the color filter array, and the R and B filters are arranged in each line of the horizontal and vertical directions of the color filter array. In addition, a ratio of the number of G pixels that help most to obtain a brightness signal of the basic array pattern is greater than each ratio of the number of R pixels and the number of B pixels that correspond to the other colors, thereby executing demosaic processing effectively.
