Various embodiments disclosed herein relate to pixel pattern conversion, and more specifically to using an adaptive filter to convert complex pixel data to non-complex pixel formats. An image processing pipeline is provided herein that comprises 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. The pattern conversion component is configured to obtain RGB-IR pixel data produced by the upstream component of the image processing pipeline, convert the RGB-IR pixel data into RGB pixel data and IR pixel data using an adaptive filter, and supply the RGB pixel data and the IR pixel data to the downstream component of the image processing pipeline.
