Abstract: Various embodiments disclosed herein relate to distorted pixel correction, and more specifically to producing an output image using variable-sized groupings of lines of pixels of an input image. An example embodiment includes a method of using variable-sized pixel groupings when processing distorted image data. The method comprises identifying a context of an image captured by an imaging system, wherein the image comprises lines of pixels that form a distorted representation of a scene, identifying, based on the context of the image, a mapping of variable-sized groupings of the lines to memory ranges in a buffer, wherein an image processing subsystem produces block rows of an output image based on the mapping, and wherein a size of each of the variable-sized groupings varies based on how many of the lines the image processing subsystem uses to produce each of the block rows, and supplying the mapping to the image processing subsystem.

Abstract: 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.

Abstract: Disclosed herein are improvements to pixel pattern conversion, upsampling, and IR decontamination processes. An example includes 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. The pattern conversion component is configured to obtain RGB-IR pixel data produced by the upstream component of the image processing pipeline and convert the RGB-IR pixel data into RGB pixel data and IR pixel data using a conversion engine. The conversion engine is configured to demosaic the RGB-IR pixel into the RGB pixel data and the IR pixel data, remosaic the RGB pixel data into an RGB pattern and the IR pixel data into an IR pattern and remove IR contamination from the RGB pixel data of the RGB pattern for use by the downstream component.

Abstract: Various embodiments disclosed herein relate to defective pixel detection and correction, and more specifically to using threshold functions based on color channels to compare pixel values to threshold values. A method is provided herein that comprises identifying a color channel of an image pixel in a frame and identifying a threshold function based at least on the color channel. The method further comprises applying the threshold function to one or more nearest-neighbor values to obtain a threshold value and determining whether a corresponding sensor pixel is defective based at least on a comparison of the image pixel to the threshold value.
