Abstract:
An image sensor may include high dynamic range imaging pixels having an inner sub-pixel surrounded by an outer sub-pixel. To steer light away from the inner sub-pixel and towards the outer sub-pixel, the high dynamic range imaging pixels may be covered by a toroidal microlens. To mitigate cross-talk caused by high-angled incident light, various microlens arrangements may be used. A toroidal microlens may have planar portions on its outer perimeter. A toroidal microlens may be covered by four additional microlenses, each additional microlens positioned in a respective corner of the pixel. Each pixel may be covered by four microlenses in a 2×2 arrangement, with an opening formed by the space between the four microlenses overlapping the inner sub-pixel.

Claim (Index 16):
An image sensor comprising an array of imaging pixels, wherein an imaging pixel in the array of imaging pixels comprises:\n an inner sub-pixel that includes a first photosensitive area; an outer sub-pixel that includes a second photosensitive area; a color filter element formed over the inner sub-pixel and the outer sub-pixel; and first, second, third, and fourth microlenses formed over the color filter element, wherein an opening formed from space between the first, second, third, and fourth microlenses overlaps the inner sub-pixel.
