Abstract
A digital projector that projects moving images from a data stream also generates black intervals selected to induce a stroboscopic effect in a viewer's eye. The black signals are interspaced with the images in a manner so as to simulate the operation of a standard movie projector thereby insuring that the effects of temporal and spatial artefacts normally associated with digital projectors are reduced.
