Abstract:
Illumination methods and apparatus are described. In some embodiments a lighting device includes one or more lighting modules. At least some but not necessarily all lighting modules include a light source, e.g., LED or bulb, a collimating lens positioned in front of said light source for generating a beam of light from light output by said light source and a beam flattening lens for flattening the beam of light in at least a first direction as it passes through the first beam flattening lens. In some but not necessarily all embodiments lighting modules are controlled based on which portion of a scene is being captured at a point in time thereby avoiding the need to illuminate the entire scene for the full duration of an image capture period. The lighting device may be used in combination with a rolling shutter and a sensor used to capture one or more images.
