1. An under-display camera system, comprising:
a pixel array configured to provide a raw data, wherein the pixel array comprises:
a plurality of color filters disposed on a plurality of first photodiodes, respectively, and configured to generate a color information in accordance with the raw data; and
a plurality of first narrowband filters disposed on a plurality of second photodiodes, respectively, and configured to generate a first narrowband information in accordance with the raw data, wherein a first spectrum linewidth of the plurality of the first narrowband filters is in a range from 5 nm to 70 nm;
a database unit of a point spread function configured to store a plurality of diffraction patterns;
a first model unit receiving the first narrowband information from the pixel array and electrically connected to the database unit of the point spread function, wherein the first model unit is configured to reconstruct an edge information from the first narrowband information based on one of the plurality of the diffraction patterns provided by the database unit of the point spread function; and
a second model unit electrically connected to the first model unit and the pixel array, wherein the second model unit is configured to obtain an image by combining the edge information with the color information.
