1. A method, comprising:
estimating a flare value for a color channel using downscaled images of images obtained via dual fisheye lenses;
adjusting the flare value based on at least one of luminance exposure compensation (LEC) or automatic color lens shading (ACLS) data to obtain an adjusted flare value; and
correcting a flare in the color channel of at least one of the images by combining the adjusted flare value with pixel values of the at least one of the images.
