An imaging system comprising: an image module configured to produce candidate image frames (72 1 -72 m) at a frame rate F, the image module being configured to capture portions of each of the candidate image frames at different times using a rolling shutter, characterized in that the image module is configured to collect data for each of the candidate image frames (72 1 -72 m) with different exposure durations (62 1 -62 m), and in that the system further comprises: a stitch module communicatively coupled to the image module and configured to produce a plurality, N, of composite image frames (70 1 -70 N) by stitching together properly exposed portions of different ones of the candidate image frames (72 1 -72 m) such that the entire frame of each of the composite image frames (70 1 -70 N) is properly exposed; a frequency determination module, communicatively coupled to the stitch module, configured to divide each of the composite image frames (70 1 -70 N) into a set of spatially-distinct segments and to determine frequency components of light incident upon a camera associated with each of the spatially-distinct segments from the pixel intensities of corresponding segments of the plurality, N, of the composite image frames (70 1 -70 N); and a flicker analysis module, communicatively coupled to the frequency determination module, configured to determine whether any of the predominant frequency components of each of the spatially-distinct segments are indicative of a flicker frequency associated with a light source of concern. an image module configured to produce candidate image frames (72 1 -72 m) at a frame rate F, the image module being configured to capture portions of each of the candidate image frames at different times using a rolling shutter, characterized in that the image module is configured to collect data for each of the candidate image frames (72 1 -72 m) with different exposure durations (62 1 -62 m), and in that the system further comprises: a stitch module communicatively coupled to the image module and configured to produce a plurality, N, of composite image frames (70 1 -70 N) by stitching together properly exposed portions of different ones of the candidate image frames (72 1 -72 m) such that the entire frame of each of the composite image frames (70 1 -70 N) is properly exposed; a frequency determination module, communicatively coupled to the stitch module, configured to divide each of the composite image frames (70 1 -70 N) into a set of spatially-distinct segments and to determine frequency components of light incident upon a camera associated with each of the spatially-distinct segments from the pixel intensities of corresponding segments of the plurality, N, of the composite image frames (70 1 -70 N); and a flicker analysis module, communicatively coupled to the frequency determination module, configured to determine whether any of the predominant frequency components of each of the spatially-distinct segments are indicative of a flicker frequency associated with a light source of concern. a stitch module communicatively coupled to the image module and configured to produce a plurality, N, of composite image frames (70 1 -70 N) by stitching together properly exposed portions of different ones of the candidate image frames (72 1 -72 m) such that the entire frame of each of the composite image frames (70 1 -70 N) is properly exposed; a frequency determination module, communicatively coupled to the stitch module, configured to divide each of the composite image frames (70 1 -70 N) into a set of spatially-distinct segments and to determine frequency components of light incident upon a camera associated with each of the spatially-distinct segments from the pixel intensities of corresponding segments of the plurality, N, of the composite image frames (70 1 -70 N); and a flicker analysis module, communicatively coupled to the frequency determination module, configured to determine whether any of the predominant frequency components of each of the spatially-distinct segments are indicative of a flicker frequency associated with a light source of concern.
