Patent attributes
An example image capture device includes an image sensor having diodes for sensing light from a target scene, a color filter array disposed above the diodes and including color filters each positioned over one of the diodes, single-diode microlenses positioned above some color filters arranged in a Bayer pattern, and multi-diode microlenses each positioned above at least two adjacent color filters that pass the same wavelengths of light to corresponding adjacent diodes below the color filters, each multi-diode microlens formed such that light incident in a first direction is collected one of the adjacent diodes and light incident in a second direction is collected in another of adjacent diodes. An image signal processor of the image capture device can perform phase detection autofocus using signals received from the adjacent diodes and can interpolate color values for the adjacent diodes.
