Abstract
Image display apparatus comprising projector means, a first modulator and a second modulator, the first and the second modulators being such as to modulate picture elements in an image whereby finite minimum image brightness above true black is reduced, and whereby the contrast range of the projected image is extended.

Image display apparatus comprising projector means, a light source, a first modulator, a second modulator, and relay means, the first and the second modulators both being such as to modulate light received from the light source, the first modulator modulating the light to produce an image, the relay means optically relaying the image to the second modulator, the second modulator being such as to further modulate the image to perform optical image enhancement whereby finite minimum image brightness above true black is reduced, whereby contrast range of the projected image is extended, and whereby the optical image enhancement achieved is determined by a driving signal to the second modulator.
