Patent ID: 8570389

Claim:
A method for enhancing imaging in low light conditions, the method comprising: acquiring a sequence of two or more images comprising at least a long image relating to long exposure time and a short image relating to short exposure time; processing the sequence of two or more images by: identifying at least one image zone of the sequence of two or more images having corresponding image levels between the long image and the short image upon gray level alignment; filtering the short image and the long image to identify image edges in the short image and the long image generating a filtered short image and a filtered long image; based on the identified image edges, masking the filtered short image and the filtered long image to identify high activity regions of the short image and the long image; based on the masking, identifying high resolution areas of the filtered short image and generating an image combination mask; and reconstructing a final image by combining the long image and the short image with the image combination mask.
