The algorithm used is now revealed! It is called Adaptive histogram equalization a digital image processing technique used to enhance the contrast of images. It differs from normal histogram equalization in the respect that the adaptive method enhances the contrast locally. Algorithm is greatly used in medical imaging like endoscopes x-rays space images from NASA and in general in cases were camera vision is difficult. For more details please follow the wiki link below

Disclaimer: this is not a night vision app. Night vision equipment uses optoelectronic image enhancement technology. This technology uses a series of optical lenses and a special electronic vacuum tube to capture and amplify the visible and infrared light that is reflected off nearby objects. Mobile phones does not have such specialized hardware therefore apps claiming to have night vision functionality are scum.
