Abstract
The present invention encompasses methods and systems of representing video in continuous time. Photons incident on pixels in an imaging array are continuously captured using a continuous time imaging sensor array to produce respective continuous time analog signals without any discontinuity in time. At each pixel, the respective continuous time analog signal is modulated into respective continuous time binary analog signals. The continuous time binary analog signals from all pixels can then be aggregated to produce a frame free video. Further, at each pixel, the respective continuous time analog signal may be modulated using a continuous time sigma delta modulator to produce the corresponding continuous time binary analog signal. The sigma delta modulator may be one of charge-based or current-based.
