Abstract
There is provided a method of and an apparatus for generating high sensitivity images in a low light level environment, the method including correcting an image acquired through short-time exposure in a low light level environment to an image corresponding to a reference exposure time defined for the low light level environment, the corrected image including a plurality of channels, detecting respective black levels for each of the channels, the detecting of the respective black levels being based on a black level intensity for the reference exposure time, adjusting the respective black levels for each of the channels of the corrected image to respective target black levels for each of the channels, and aligning a value of each of the channels using the respective target black levels.
