Abstract: In various examples, an image processing pipeline may switch between different operating or switching modes based on speed of ego-motion and/or the active gear (e.g., park vs. drive) of a vehicle or other ego-machine in which an RGB/IR camera is being used. For example, a first operating or switching mode that toggles between IR and RGB imaging modes at a fixed frame rate or interval may be used when the vehicle is in motion, in a particular gear (e.g., drive), and/or traveling above a threshold speed. In another example, a second operating or switching mode that toggles between IR and RGB imaging modes based on detected light intensity may be used when the vehicle is in stationary, in park (or out of gear), and/or traveling below a threshold speed.

Abstract: In various examples, an image processing pipeline may toggle between IR and RGB imaging modes in response to different thresholds of detected light intensity that depend on the toggling direction (e.g., a lower intensity threshold to switch from RGB to IR imaging and a higher intensity threshold to switch from IR to RGB imaging). For example, the image processing pipeline may switch from RGB to IR imaging in response to detecting an amount of light intensity (e.g., average intensity in a green channel) below a first threshold, and the image processing pipeline may switch from IR to RGB imaging in response to: (i) detecting an amount of light intensity (e.g., average intensity in a green channel) that exceeds a second threshold, and/or (ii) detecting a ratio of detected light intensities (e.g., IR to green) below a third threshold.
