Patent ID: 8638379

Claim:
A solid-state image pickup device comprising: a pixel region having a plurality of light receiving areas arranged relatively in columns and rows, the light receiving areas configured to convert light into signal charges, the light receiving areas corresponding to at least four light wavelengths, at least three of which are different, each light receiving area corresponding to one light wavelength; and transistors including signal charge amplifying transistors and reset transistors, wherein, light receiving areas corresponding to a first light wavelength and light receiving areas corresponding to a second light wavelength alternate along a first row, the first light wavelength being different from the second light wavelength, light receiving areas corresponding to a third light wavelength and light receiving areas corresponding to a fourth light wavelength alternate along a second row adjacent to the first row, the third light wavelength being different from the fourth light wavelength, the light receiving areas corresponding to the first light wavelength and the light receiving areas corresponding to the third light wavelength alternate along a first column, the light receiving areas corresponding to the second light wavelength and the light receiving areas corresponding to the fourth light wavelength alternate along a second column adjacent to the first column, respective diagonally adjacent light receiving areas form a light receiving area pair, two light receiving area pairs adjacent along a column direction are commonly connected to a respective signal charge amplifying transistor and a respective reset transistor, one of the respective amplifying transistor and the respective reset transistor is located in a first peripheral region facing the light receiving areas in the first and second columns along the first row, and is positioned nearer to a side of a light receiving area of the light receiving areas in the first and second columns along the first row that corresponds to a shorter light wavelength such that a first substantial space without a transistor disposed therein exists in a periphery of the other one the light receiving areas in the first and second columns along the first row, and a remaining one of the respective amplifying transistor and the respective reset transistor is located in a second peripheral region facing the light receiving areas in the first and second columns along the second row, and is positioned nearer to a side of a light receiving area of the light receiving areas in the first and second columns along the second row that corresponds to a shorter light wavelength such that a second substantial space without a transistor disposed therein exists in a periphery of the other one of the light receiving areas in the first and second columns along the second row.
