Dual sensor readout channel to allow for frequency detection

A method, the method comprising:

• receiving a plurality of images acquired by a camera onboard a host vehicle, wherein the camera includes a sensor having a plurality of pixels, and wherein the plurality of images includes:
• a first portion of the plurality of images captured using the plurality of pixels at a first frame capture rate, the first portion of images being received via a first channel, the first capture rate being selected to coincide with an expected light-generation waveform of a flickering light source, and
• a second portion of the plurality of images captured using the plurality of pixels at a second frame capture rate, the second portion of images being received via a second channel, the second frame capture rate being selected as a non-harmonic frequency of the expected light-generation waveform and being different from the first frame capture rate, wherein the first frame capture has a frequency of 18 Hz and the second frame capture rate has a frequency of 15 Hz, 20 Hz, 30 Hz, 60 Hz, or 120 Hz;
• using the first portion of the plurality of images received via the first channel to detect flickering and non-flickering light sources in an environment of the host vehicle;
• and
• providing, based on the second portion of the plurality of images received via the second channel, images for showing on one or more human-viewable displays.

A non-transitory computer readable medium containing instructions that when executed by at least one processor, cause the at least one processor to perform a method, the method comprising:

• receiving a plurality of images acquired by a camera onboard a host vehicle, wherein the camera includes a sensor having a plurality of pixels, and wherein the plurality of images includes:
• a first portion of the plurality of images captured using the plurality of pixels at a first frame capture rate, the first portion of images being received via a first channel, the first capture rate being selected to coincide with an expected light-generation waveform of a flickering light source, and
• a second portion of the plurality of images captured using the plurality of pixels at a second frame capture rate, the second portion of images being received via a second channel, the second frame capture rate being selected as a non-harmonic frequency of the expected light-generation waveform and being different from the first frame capture rate, wherein the first frame capture has a frequency of 18 Hz and the second frame capture rate has a frequency of 15 Hz, 20 Hz, 30 Hz, 60 Hz, or 120 Hz;
• using the first portion of the plurality of images received via the first channel to detect flickering and non-flickering light sources in an environment of the host vehicle;
• and
• providing, based on the second portion of the plurality of images received via the second channel, images for showing on one or more human-viewable displays.
