Abstract
An image sensor includes an array of pixels, each of the pixels includes a sensor layer and a color filter layer disposed on the sensor layer. Each of the pixels further includes a first meta-surface layer disposed over the color filter layer and a second meta-surface layer disposed on the first meta-surface layer. The second meta-surface layer has a meta-structure region corresponding to each of the pixels. The shifting value S1 between the center of the color filter layer and the center of the sensor layer, the shifting value S2 between the center of the first meta-surface layer and the center of the sensor layer, and the shifting value S3 between the center of the second meta-surface layer and the center of the sensor layer all increase with the distance from the center of the image sensor.
