摘要： An example image sensor includes first, second, and third micro-lenses. The first micro-lens is in a first color pixel and has a first curvature and a first height. The second micro-lens is in a second color pixel and has a second curvature and a second height. The third micro-lens is in a third color pixel and has a third curvature and a third height. The first curvature is the same as both the second curvature and the third curvature and the first height is greater than the second height and the second height is greater than the third height, such that light absorption depths for the first, second, and third color pixels are the same.
