Method and apparatus for increasing brightness of image captured in low light

摘要

An exemplary method for increasing brightness of an image captured in low light includes: transforming the captured image into an original image that has a brightness component; copying the brightness component of the original image as a brightness image; inverting the brightness image into a negative image; and incorporating the negative image into the original image such that a predetermined percentage of gray scale values of pixels of the negative image corresponding to pixels in a dark portion of the original image are respectively added to gray scale values of the pixels in the dark portion of the original image to produce a processed image.
