Abstract
Methods and apparatus for digitally enhancing images are disclosed. In one embodiment, a method includes performing a wavelet transformation process on an acquired image to provide a low pass spatial frequency. A dynamic range and a mixing value are then determined from the low pass spatial frequency, and the mixing value is applied to provide a transformed output image. The transformed output image is then reformatted to provide a mixed output image, and the mixed output image is subtracted from the acquired image to provide an enhanced image. In an alternate embodiment, a method includes analyzing an acquired image to provide a high sensitive low light image and a low sensitive high light image, and then summing the high sensitive low light image and the low sensitive high light image to create an enhanced image.
