Abstract: A stroboscopic system for the purpose of capturing an image of a rapidly moving scene under low-light conditions but having widely varying interfering ambent light sources present, which sources vary with each video frame captured. The system includes a referencing method which removes the effects of the ambient light that would otherwise overlap the features of interest of the image being captured and would otherwise act to obscure the image.

Abstract: This invention describes a set of simple yet novel methods for capturing photographs of moving objects that are constrained to lie within a relatively flat object region that is not necessarily perpendicular to the axis of the camera lens. Using these methods, one can select a focal plane and an object region that is not that of a normal camera, and, when objects are constrained to move within that object region, one can successfully photograph them no matter where they appear within the field without losing focus.
