1. An image sensor, comprising:
a color filter array comprising:
a first color filter comprising a first number of blue pass filtering elements, the first number of red pass filtering elements, and green pass filtering elements arranged in a first pattern, wherein a number of green pass filtering elements in the first pattern is twice the first number, and
a second color filter comprising a second number of blue pass filtering elements, the second number of red pass filtering elements, and green pass filtering elements arranged in a second pattern, wherein a number of green pass filtering elements in the second pattern is twice the second number, and
wherein the second number is greater than the first number;
a sensing array comprising first sensing elements arranged in a first sensing region configured to receive light passing through the first color filter, and second sensing elements arranged in a second sensing region configured to receive light passing through the second color filter; and
a processor configured to generate sensing data based on a sensing of the first sensing elements and a sensing of the second sensing elements,
wherein the second color filter surrounds an area of the first color filter,
wherein the processor is further configured to restore a first image corresponding to a first field of view (FOV) based on first sensing data corresponding to the sensing of the first sensing elements, and restore a second image corresponding to a second FOV that extends further than the first FOV, based on the first sensing data and second sensing data corresponding to the sensing of the second sensing elements, and
wherein in restoring the first image, the processor is configured to:
determine pixel values of first pixels constituting the first image from a sensing value obtained by summing intensity values sensed by the first sensing elements grouped based on a first binning size;
generate channel images for each color channel from the pixel values of the first pixels; and
restore the first image using the channel images.
