Abstract: A dual-modulation projection system (100) includes a light source (102), a phase modulator (104), an amplitude modulator (106), and a controller (110) having temporal lightfield simulation capabilities (114). The phase modulator (104) spatially modulates a lightfield from the light source (102) to generate an intermediate image on the amplitude modulator (106). The amplitude modulator (106) spatially modulates the intermediate image to form a final image. The controller (110) models the phase state of the phase modulator (104) during transitions between phase modulator frames and generates lightfield simulations of the intermediate image during the transition. The controller (110) utilizes the lightfield simulations to generate and provide sets of amplitude drive values to the amplitude modulator (106) at a faster rate than that at which the phase modulator (104) is capable of switching.

Abstract: A display for displaying image data includes defining virtual color gamuts based on a plurality of primary display colors associated with a light source. At least one of the virtual color gamuts is defined to approximate an established color gamut. Intensity values associated with the virtual color gamuts are generated based on received video data, and the intensity values associated with the virtual color gamuts are used to generate drive values for the primary colors of the light source. A display using one or more virtual color gamuts is also disclosed.

Abstract: A novel projection system includes a light source, a phase modulator, an amplitude modulator, and a controller having temporal lightfield simulation capabilities. The phase modulator spatially modulates a lightfield from the light source to generate an intermediate image on the amplitude modulator. The amplitude modulator spatially modulates the intermediate image to form a final image. The controller models the phase state of the phase modulator during transitions between phase modulator frames and generates lightfield simulations of the intermediate image during the transition. The controller utilizes the lightfield simulations to generate and provide sets of amplitude drive values to the amplitude modulator at a faster rate than that at which the phase modulator is capable of switching.

Abstract: A system and method for displaying image data comprise receiving 2D video data, generating, from the video data, a first plurality of intensity values of virtual primaries of a first virtual color gamut and a second plurality intensity values of a second virtual color gamut, the first plurality of intensity values being below a luminance threshold and approximating a predefined color gamut and the second plurality of intensity values being above the luminance threshold, converting the first plurality of intensity values into a third plurality of intensity values of predefined primaries of a first projection head of a display system and the second plurality of intensity values into a fourth plurality of intensity values of predefined primaries of a second projection head of the display system, and dynamically adjusting pixel levels of spatial modulators of the display system based on the third plurality and the fourth plurality of intensity values.
