    • A solid-state image sensor includes a photosensitive cell array and a dispersing element array. Each unit block 40 of the photosensitive cell array includes four photosensitive cells 2a, 2b, 2c and 2d. The dispersing element array makes light, obtained by subtracting a light ray with a first color component (C1) from incoming light (W) and adding a light ray with a second color component (C2) thereto, incident on the first photosensitive cell 2a, also makes light, obtained by subtracting the light ray with the second color component (C2) from the incoming light (W) and adding the light ray with the first color component (C1) thereto, incident on the second photosensitive cell 2b, further makes light, obtained by subtracting a light ray with a third color component (C3) from the incoming light (W) and adding the light rays with the first and second color components (C4=C1+C2) thereto, incident on the third photosensitive cell 2c, and further makes light, obtained by subtracting the light rays with the first and second color components (C4) from the incoming light (W) and adding the light ray with the third color Component (c3)thereto, incident on the fourth photosensitive cell 2d.
    • 固态图像传感器包括感光单元阵列和分散元件阵列。 感光单元阵列的每个单元块40包括四个感光单元2a,2b,2c和2d。 分散元件阵列通过从入射光(W)减去具有第一颜色成分(C1)的光线并将入射到第一感光单元2a上的具有第二颜色成分(C2)的光线添加到其中而获得光, 还通过从入射光(W)减去具有第二颜色分量(C2)的光线并将入射到第二感光单元2b上的与第一颜色分量(C1)的光线相加的光进一步制成光, 通过从入射光(W)减去具有第三颜色分量(C3)的光线并将其中具有第一和第二颜色分量(C4 = C1 + C2)的光线加到入射到第三感光单元上的光, 并且进一步通过从入射光(W)减去具有第一和第二颜色分量(C4)的光线并将其中的第三颜色分量(c3)的光线加到入射到第四感光体上而获得的光 细胞2d。
