Claim 0:
1. A computer-implemented method for preserving dynamic range in images, the computer-implemented method comprising:
receiving, at an autonomous vehicle system associated with an autonomous vehicle navigating a route, image data from an image sensor of the autonomous vehicle;
generating, by the autonomous vehicle system, a dual channel HDR and most significant bit (MSB) output to prevent light saturated signals in the image data captured in a low light environment by:
buffering a first portion of the image data from the image sensor;
performing HDR processing on a second portion of the image data in parallel with buffering the first portion of the image data to generate an HDR output; and
performing an 8-bit MSB processing to remove light saturation from the processed second portion of the image data of the low light environment that preserves the dynamic range of the HDR processing, and generating an 8-bit MSB output.
