Claim One:
1. A method for generating a range video sequence from a scannerless range imaging system of the type comprising an illuminator for illuminating a scene with modulated illumination; an image modulating component for receiving and modulating the modulated illumination reflected from the scene; an image capture element for capturing images output by the image modulating component, including an image bundle of at least three phase offset images each incorporating a phase delay corresponding to a distance of objects in the scene from the illuminator, wherein each phase offset image of an image bundle also incorporates a phase offset distinct for each image, said method comprising the steps of: (a) defining a frame rate, wherein the frame rate is the number of frames of the range video sequence per unit of time; (b) acquiring for each frame a sequence of three or more phase offset images corresponding to the modulated illumination reflected from the scene, whereby the sequence forms an image bundle; and (c) computing for each of the image bundles a range image using the corresponding phase offset images, thereby forming a range video sequence at the defined frame rate.
