Adaptive low-light image processing
First Claim
Patent Images
1. A method for enhancing imaging in low light conditions, comprising:
- acquiring image data relating to a plurality of consecutive images;
applying spatial and temporal filtering to a signal corresponding to the acquired image data;
detecting local motion indication in the filtered image data;
filtering the detected local motion indication;
using a look up table, said look up table assigning greater weights to areas of greater local motion indication and lower weights to areas of smaller local motion indication, to obtain a local motion factor; and
producing final image data by combining the acquired image data with a temporally filtered signal of the acquired image data using the local motion factor.

Abstract
A method for enhancing imaging in low light conditions, comprising: acquiring image data relating to a plurality of consecutive images; determining a local motion factor relating to the consecutive images by specifically processing the consecutive images in a predetermined manner in order to obtain an image mask that represents information about local motion; and processing the consecutive images, incorporating the image mask, to obtain final usable image information.
