Abstract

Illumination methods and apparatus which are well suited for use with camera devices are described. In some but not all embodiments a plurality of lighting elements are provided and controlled in a manner which is synchronized with operation of a rolling shutter. In some such embodiments the portion of an area being captured is illuminated during the image capture process, lighting elements corresponding to area portions not being captured are not activated when the corresponding area portion is not being captured. Some embodiments are directed to lighting devices that include one or more lighting modules, some of which include a light source, e.g., LED or bulb, a collimating lens positioned in front of the light source and a beam flattening lens. The lighting device maybe used in combination with a rolling shutter and an image sensor or for other purposes.
