  • Patent number: 8525199
    Abstract: In a solid-state image capturing device having the locations of photodiodes in each pixel unit to be different according to a sequence, the light receiving sensitivity and the luminance shading characteristic are improved. A circumferential portion of a microlens 12 which is arranged above a corresponding photodiode 11 is formed so as to overlap an adjacent microlens 12 thereto, and the locations of microlenses 12 in each pixel unit are different according to a sequence. Light of an image that is incident upon each of the microlenses 12 is incident upon approximately the same portion (e.g., central portion) of each of the respective photodiodes 11.
