NeuralCam is a photo app for the iPhone that uses computational photography and machine learning to take bright photos in low light settings. It combines multiple underexposed photos taken in quick succession to reduce noise and increase detail and brightness. The photos are aligned, patches are merged using a reference frame, and a deep learning model is used to brighten the composite image while controlling noise and color accuracy. The founders plan to expand the technology to additional features like night video and day mode enhancement.
