Abstract
A technique includes pulse width modulating an illuminating beam of a light to establish a pixel intensity and modulating the illuminating beam to create different tonal resolution ranges for the pixel intensity.
Claims37
A method comprising:
- pulse width modulating an illuminating beam of a light to establish a pixel intensity;
- and
- modulating the illuminating beam to create different tonal resolution ranges for the pixel intensity.
An apparatus comprising:
- a spatial light modulator to modulate a beam of light to establish a pixel intensity;
- and
- a second modulator to modulate an illuminating beam to create different tonal increment ranges for forming the pixel intensity.
An apparatus comprising:
- a modulator to modulate illumination that is incident upon a spatial light modulator to create different resolution ranges for a pixel intensity produced by the pixel cells of the spatial light modulator.
A system comprising:
- a flash memory to receive data indicative of a pixel intensity;
- a spatial light modulator to modulate a beam of light to establish the pixel intensity in response to the data;
- and
- a second modulator to modulate the illumination level of the spatial light modulator to create different resolution ranges for the pixel intensity.
