摘要： The present disclosure provides a color filter array. The color filter array includes at least one minimal repeating unit, wherein the at least one minimal repeating unit includes a first filter set and a second filter set. The first filter set includes a first color filter having a first spectrum, two second color filters having a second spectrum and a third color filter having a third spectrum. The second filter set includes a fourth color filter having the first spectrum, two fifth color filters having the second spectrum, a sixth color filter having the third spectrum and a plurality of broadband filters. The second filter set is arranged to form a quadrilateral annulus, and the first filter set is positioned in an interior of the quadrilateral annulus. The present disclosure also provides a demosaicing method for an image captured via the color filter array.

摘要： An optical device includes a photoelectric conversion layer, an anti-reflection layer, an underlying layer, a bottom meta layer, and a top meta layer. The photoelectric conversion layer includes a plurality of photodiodes. The anti-reflection layer is disposed on the photoelectric conversion layer. The underlying layer is disposed on the anti-reflection layer. The bottom meta layer is disposed on the underlying layer and includes a plurality of bottom meta units and a filling between the bottom meta units, in which the filling is continuously extend from the underlying layer, and a material of the filling is the same as a material of the underlying layer. The top meta layer is disposed above the bottom meta layer and includes a plurality of top meta units and a plurality of air recesses, in which the plurality of air recesses are respectively disposed between two adjacent top meta units.
