    Abstract: A method for generating a glare-reduced image from images captured by a camera device of a subject vehicle includes obtaining a short-exposure image and a long-exposure image and generating a resulting high dynamic range image based on the short-exposure and long-exposure images. Pixel values are monitored within both the short- and long-exposure images. A light source region is identified within both the short- and long-exposure images based on the monitored pixel values. A glaring region is identified based on the identified light source region and one of calculated pixel ratios and calculated pixel differences between the monitored pixel values of the long- and short-exposure images. The identified glaring region upon the resulting high dynamic range image is modified with the identified light source region within the short-exposure image. The glare-reduced image is generated based on the modified identified glaring region upon the resulting HDR image.

    Abstract: A method for displaying a captured image on a display device. A scene is captured by at least one vision-based imaging device. A virtual image of the captured scene is generated by a processor using a camera model. A view synthesis technique is applied to the captured image by the processor for generating a de-warped virtual image. A dynamic rearview mirror display mode is actuated for enabling a viewing mode of the de-warped image on the rearview mirror display device. The de-warped image is displayed in the enabled viewing mode on the rearview mirror display device.

    Abstract: A vehicle imaging system includes an image capture device capturing an image exterior of a vehicle. The captured image includes at least a portion of a sky scene. A processor generates a virtual image of a virtual sky scene from the portion of the sky scene captured by the image capture device. The processor determines a brightness of the virtual sky scene from the virtual image. The processor dynamically adjusts a brightness of the captured image based the determined brightness of the virtual image. A rear view mirror display device displays the adjusted captured image.
