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.
Claims17
A digital projector comprising:
- an input receiving digital data defining image frames;
- and
- an optical modulator generating a series of images corresponding to said digital data, said images being separated by black intervals, said optical modulator generating said black intervals with a duration selected to induce a blink effect in the eye of a viewer, to improve relative motion perception.
A digital projector projecting moving images from a stream of data arranged in digital frames, said projector comprising:
- an input receiving said stream of data;
- a timer generating blink signals in synchronism with said digital frames, said blink signals defining a black interval having a duration selected to induce a blink effect to improve relative motion perception;
- and
- an optical image generator that generates a sequence of optical images corresponding to said sequence of digital frames, said optical images being separated by said black intervals.

A method of generating moving images from data comprising:
- generating blink signals defining black intervals having a duration selected to induce a blink effect in the eyes of a viewer to improve relative motion perception;
- converting said data into images;
- and
- projecting said images on a screen with said images being separated by said black intervals.
