A meta optical device is provided. The meta optical device includes an array of meta structures. Each of the meta structures includes a plurality of stacked layers at least including a first layer with a first refractive index and a second layer with a second refractive index. The first refractive index and the second refractive index are different.

Meta optical device, optical system, and method for aberration correction

The optical device includes a first photodiode, a second photodiode, and a hybrid absorber. The hybrid absorber is disposed above the first photodiode and the second photodiode. The hybrid absorber includes a color filter layer and a plurality of metal-insulator-metal structures. The color filter layer includes a first color filter disposed on the first photodiode and a second color filter disposed on the second photodiode, in which the first color filter is different from the second color filter. The plurality of metal-insulator-metal structures are disposed above the first photodiode and free of disposed above the second photodiode.

Optical device

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.

Color filter array and demosaicing method

An operating method of an under-display camera system includes: providing a raw data by a pixel array; generating, by a plurality of color filters respectively disposed on a plurality of first photodiodes of the pixel array, a color information in accordance with the raw data; generating, by a plurality of first narrowband filters respectively disposed on a plurality of second photodiodes of the pixel array, a first narrowband information in accordance with the raw data, wherein a spectrum linewidth of the plurality of first narrowband filters is in a range from 5 nm to 70 nm; reconstructing an edge information from the first narrowband information based on one of a plurality of diffraction patterns provided by a database unit of a point spread function; and obtaining an image by combining the edge information with the color information.
