Abstract: Quad photodiode microlens arrangements, and associated systems and methods. In one embodiment, a plurality of pixels are arranged in rows and columns of a pixel array disposed in a semiconductor material. The plurality of pixels includes green (G) pixels, red (R) pixels, blue (B) pixels and clear (C) pixels. Each pixel comprises a plurality of photodiodes that are configured to receive incoming light through an illuminated surface of the semiconductor material. A plurality of small microlenses are distributed over individual photodiodes of clear (C) pixels. A plurality of large microlenses are distributed over individual green (G) pixels. A diameter of the small microlenses is smaller than a diameter of the large microlenses.
