HIGH-LUMINOSITY PROJECTION DISPLAYS AND RELATED METHODS Russian patent published in 2015 - IPC G06T1/00 G02F1/13 G03B21/26 

FIELD: physics, computer engineering.

SUBSTANCE: invention relates to information display devices, particularly projection displays. A high-luminosity projector system is disclosed. The system includes an image processor configured to process image data in order to output a main image and a high-brightness image, having high-brightness areas, by comparing luminosity of pixels in image data with a first threshold and identifying in the image data pixels whose luminosity exceeds the first threshold as belonging to high-brightness areas. The system also includes a high-brightness projector, which projects light in accordance with the high-brightness image superimposed with the main image to provide increased luminosity in high-brightness areas. The high-brightness projector includes a spatially-modulated light source, mounted to illuminate a spatial light modulator.

EFFECT: high luminosity of light by projecting concentrated light from a light source in order to output light which is spatially modulated using an image data-based technique.
