Claim One:
1. Method for generating a glare-reduced image from images captured by a camera device of a subject vehicle, comprising: obtaining a short-exposure image and a long-exposure image captured by the camera device; generating a resulting high dynamic range (HDR) image based on the short-exposure and long-exposure images; monitoring pixel values within both the short-exposure and the long-exposure images; identifying a light source region within both the short-exposure and the long-exposure images based on the monitored pixel values; calculating one of pixel ratios and pixel differences between the monitored pixel values of the long-exposure and the short-exposure images; identifying a glaring region based on the identified light source region within both the short-exposure and the long-exposure images and one of calculated pixel ratios and calculated pixel differences; modifying the identified glaring region upon the resulting HDR image with a short-exposure region corresponding to the identified light source region within the unmodified short-exposure image, comprising increasing the portion of the unmodified identified light source region within the short-exposure image and decreasing the portion of the identified light source region within the long-exposure image applied thereto; and generating a glare-reduced image based on the modified identified glaring region upon the resulting HDR image.
