True color image by modified microlens array

摘要

An image sensor array includes a substrate having at least three image sensors located therein. The image sensor array also includes a blue filter positioned proximate to the first image sensor; a green filter proximate to the second image sensor; and a red filter proximate to the third image sensor A first microlens is positionally arranged with the blue filter and the first image sensor; a second microlens is positionally arranged with the green filter and the second image sensor; and a third microlens is positionally arranged with the red filter and the third image sensor. The first microlens has a larger effective area than the second microlens, and the second microlens has a larger effective area than the third microlens.
