Abstract: Methods and systems are provided for controlling camera images for a camera of a vehicle are provided. In certain examples, a vehicle includes a camera, an input unit, and a processor. The input unit is configured to obtain data pertaining to a light pattern in proximity to the vehicle. The processor is configured to at least facilitate: (i) determining the light pattern in proximity to the vehicle using the data; and (ii) providing instructions for selectively binning the camera images based on the light pattern, the selectively binning including binning first pixels together for a particular image or portion thereof, but leaving second pixels for the particular image un-binned, based on the light pattern.

Abstract: A method and system to perform dynamic demosaicing for a camera in a vehicle involve an array of image sensors of the camera to obtain light intensity values. Each image sensor of the array of image sensors represents a pixel. An array of filters of the camera overlays the array of image sensors and restricts a wavelength range for which the one image sensor of the array of image sensors obtains the light intensity value. The array of filters includes at least two different types of filters corresponding with two different wavelength ranges. A processor estimates a current state associated with the vehicle and selects a demosaicing algorithm based on the current state such that, for each pixel, the demosaicing algorithm facilitates an estimate of the light intensity value at a different wavelength range than the wavelength range for which the corresponding image sensor obtained the light intensity value.
