PERFORMANCE RELIGHTING AND REFLECTANCE TRANSFORMATION WITH TIME-MULTIPLEXED ILLUMINATION

A lighting apparatus may be configured to illuminate a subject while the subject is undergoing a motion during a time period. An imaging system may be configured to generate image data representative of a sequence of frames of the moving subject. A controller may be configured to drive the lighting apparatus and the imaging system so that the lighting apparatus sequentially illuminates the moving subject with a time-multiplexed series of lighting conditions, and so that each one of the frames shows the subject illuminated with a respective one of the lighting conditions. The controller may be further configured to process the image data to generate re-illumination data representative of novel illumination conditions under which the subject can be re-illuminated, subsequent to the time period.
