ABSTRACT:
A solid state image sensor includes an array of pixels and a corresponding array of microlenses. The positions of the microlenses relative to their corresponding pixels may vary according to the distances of the pixels from a central optical axis of the image sensor to substantially eliminate vignetting of light collected by the microlenses.
