1. An image processing pipeline, comprising:
an upstream component;
a pattern conversion component downstream with respect to the upstream component in the image processing pipeline; and
a downstream component relative to the pattern conversion component;
wherein the pattern conversion component is configured to:
obtain red, green, blue and infrared (RGB-IR) pixel data produced by the upstream component of the image processing pipeline;
convert the RGB-IR pixel data into red, green and blue (RGB) pixel data and infrared (IR) pixel data using a conversion engine configured to:
demosaic the RGB-IR pixel data into the RGB pixel data and the IR pixel data;
remosaic the RGB pixel data into a RGB pattern and the IR pixel data into an IR pattern; and
remove IR contamination from the RGB pixel data of the RGB pattern; and
supply the RGB pattern and the IR pattern to the downstream component of the image processing pipeline.
