Moreover, the image information of each green sub-pixel in the pixel array S1 is multiplied by the weight value of the conversion matrix Matrix_G, and then summed, so that the image information of the green sub-pixel G1 can be obtained, where G 1=0.5625 × G +0.1875×0+0.1875×0+0.0625×0=0.5625 G

In the same way, the image information of the green sub-pixels G2~G4 can be obtained as follows: G 2=0.5625×0+0.1875× G +0.1875×0+0.0625×0=0.1875 G

G 3 = 0.5625 × 0 + 0.1875 × G + 0.1875 × 0 + 0.0625 × 0 = 0.1875 G

G 4 = 0.5625 × 0 + 0.1875 × 0 + 0.1875 × 0 + 0.0625 × G = 0.0625 G

In other words, in the present embodiment, the image information of the green sub-pixel G originally corresponding to the first color space is allocated to the four 2×2 green sub-pixels G1 to G4 in the diagonal direction by the 2×2 conversion matrix Matrix_G.
