Light control for improved near infrared sensitivity and channel separation for an image sensor. In one embodiment, an image sensor includes: a plurality of photodiodes arranged in rows and columns of a pixel array; and a light filter layer having a plurality of light filters configured over the plurality of photodiodes. The light filter layer has a first side facing the plurality of photodiodes and a second side facing away from the first side. The image sensor also includes a color filter layer having a plurality of color filters configured over the plurality of photodiodes. The color filter layer has a first surface facing the second side of the light filter layer and a second surface facing away from the first layer. Individual micro-lenses are configured to direct incoming light through corresponding light filter and color filter onto the respective photodiode.
