A method comprising receiving data representing light intensity values corresponding to a flicker pattern of a reference light source powered by an alternating current (AC); operating a controllable illumination source, based, at least in part, on said data; capturing, using an imaging device, a sequence of images of a scene illuminated, at least in part, by said controllable illumination source; estimating an intensity value for at least one pixel in said array, correspondingly in each of said images in said sequence of images; and determining a temporal point in said flicker pattern of said reference light source, based, at least in part, on said estimating.

Computational imaging of the electric grid

Systems and methods for imaging scenes illuminated by light sources that are powered by alternating current. Data concerning these light sources are extracted from the imagery. Systems comprising a rolling shutter imaging sensor and configured to de-flicker images with spatial flicker are also provided.
