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.
