Abstract
Some embodiments provide a color image sensor and color image sampling method that uses multiple-layer pixels and is capable of producing color images without using absorption color filters (e.g., such as employed in conventional CFAs). In accordance with some embodiments of the color image sensor device and color image sampling method, frequency-dependent reflectors are incorporated between the photodetection layers of multiple-layer (e.g., two layer) pixels.
Claims12
A color image sensor that comprises a plurality of multi-layer pixels, the color filter array comprising:
- a plurality of kernels, each kernel comprising an identical configuration of multi-layer pixels;
- and
- wherein at least on multi-layer pixel in each kernel includes a dielectric frequency-dependent reflector disposed between and adjacent to an upper photoconversion layer and a lower photoconversion layer.
