Abstract
A system and method for detecting movement of an object outside a line-of-sight of a camera is disclosed. The camera acquires images of a target that is impacted by light that is scattered from the object and by ambient light, and of a reference that is impacted by the ambient light. A processing circuitry can be configured to detect the movement of the object by calculating, for each of a plurality of acquired images, a compensated light intensity value (LIV), being a target LIV that is based on pixels in the respective acquired image that represent the target, as modified, based on a reference LIV that is based on pixels in the respective acquired image that represent the reference, to reduce an effect, on the target LIV, of changes in the ambient light during a time period between acquiring a given image and the acquiring of the respective acquired image.
