Claim:
1. An image sensor comprising: at least a first row and a second row of photodiodes, each photodiode being coupled with an associated transistor, each associated transistor including a gate, the first and second row of photodiodes forming a series of 2×2 Bayer-pattern units; wherein: in each Bayer-pattern unit, a first photodiode and a second photodiode in the first row are designated respectively as a first green pixel and a blue pixel, and a third photodiode and a fourth photodiode in the second row are designated respectively as a red pixel and a second green pixel; a position of the gate of the transistor associated with the first photodiode relative to the first photodiode and a position of the gate of the transistor associated with the fourth photodiode relative to the fourth photodiode are the same; and for each Bayer-pattern unit, outputs of the two photodiodes in one of the first row and the second row are coupled to a common node, outputs of the two photodiodes in the other of the first row and the second row are coupled to different nodes, and each output of the two photodiodes in the other of the first row and the second row is coupled to another common node in a neighboring Bayer-pattern unit.
