Patent ID: 8030692

Claim:
A solid state image sensing device in which a plurality of pixels are disposed in a matrix on a two-dimensional plane and transistors are shared to read pixel data from a light receiving device in each of the plurality of pixels, comprising: a plurality of light receiving devices disposed with different pitches in at least one of a column direction and a row direction; and a plurality of micro-lenses which are used to collect incident light of each of the plurality of light receiving devices and are disposed with different pitches in accordance with positions of the light receiving devices, wherein a center pitch of each of the light receiving devices and micro-lenses changes by a periodic of every consecutive four pieces of pixels in a row direction, each of the consecutive four pieces of pixels in a row direction includes a light receiving device and a first transistor to transfer a charge signal outputted from the light receiving device, each of a consecutive two pieces of pixels among the consecutive four pieces of pixels shares a signal voltage conversion unit to convert the charge signal, which is outputted from the light receiving device and are transferred by the first transistor, to a voltage, the consecutive four pieces of pixels shares a signal voltage read unit comprising a second transistor capable of resetting voltage of the signal voltage conversion unit, a third transistor to amplify a voltage outputted from the signal voltage conversion unit as input, and a fourth transistor to select a row to which a pixel belongs and to output the amplified voltage to an exterior, the light receiving device/the signal voltage conversion unit and two of the first transistor/the light receiving device/the third transistor and the fourth transistor/the light receiving device/the signal voltage conversion unit and two of the first transistor/the light receiving device/the second transistor are disposed in that order, and a center pitch length between two light receiving devices between which the third transistor and the fourth transistor are inserted and a center pitch length between micro-lenses corresponding to the two light receiving devices between which the third transistor and the fourth transistor are inserted are longer than a center pitch length between two light receiving devices between which the third transistor and the fourth transistor are not inserted and a center pitch length between micro-lenses corresponding to the two light receiving devices between which the third transistor and the fourth transistor are not inserted, respectively.
