  • Publication number: 20090141200
    Abstract: In one embodiment, a method includes transmitting one or more light beams by a first portion of a light modulator formed outwardly from a substrate. The one or more transmitted light beams are spatially integrated. A second portion of the light modulator is formed outwardly from the substrate. The second portion of the light modulator spatially integrates the transmitted light beams.

  • Publication number: 20090128786
    Abstract: An imaging system comprises a light valve having an array of light valve pixels. For processing grayscale/color images, each light valve pixel represents a discrete grayscale level. During image processing, desired grayscales can be accomplished by imaging the light valve pixels onto the target such that the perceived grayscale of each target pixel is a sum of grayscales represented by a plurality of light valve pixels.

  • Publication number: 20090066718
    Abstract: System and method for image-based color sequence reallocation in sequential color display systems. A method comprises generating a color signal from an image to be displayed, wherein the color signal contains light intensity information, computing percentages of the color sequence to be allocated to each color in a set of colors in a sequential color display system, wherein the computing is based on the light intensity information, allocating the color sequence based on the computed percentages, and displaying the image using the color sequence. The allocation of the color sequence based on the image allows for the elimination of color intensities that are greater than needed in displaying the image. Portions of the color sequence formerly used to display the eliminated color intensities may be used to display colors with usable intensities, thereby increasing the brightness of images.

  • Publication number: 20090066620
    Abstract: Adaptive pulse-width modulated sequences for sequential color display systems and methods. A method for displaying an image comprises receiving the image, computing a duty cycle for the image, generating a color sequence based on the computed duty cycle, and displaying the image using the color sequence. The generating comprises assigning a color cycle order to display time blocks in the color sequence, and assigning bitplane states for each display time block in the color sequence.

  • Patent number: 7483587
    Abstract: Filtering image information to generate a dithered image includes receiving input image information corresponding to an image generated using a first array comprising a first number of smaller pixels. Intermediate image information is generated from the input image information. The intermediate image information is generated to produce the image using a second array comprising a second number of larger pixels, where the second number less than the first number. A frequency response associated with the image produced using the second array exhibits effects. The intermediate image information is repeatedly filtered to generate updated image information from the intermediate image information and to compensate for the effects. Sub-image information is generated from the updated image information, the sub-image information corresponding to a dithered image.

  • Publication number: 20090009590
    Abstract: According to various illustrative embodiments, a device, system, and method for reducing stereoscopic phase-lag distortion under motion in a 3-dimensional video display are described. In one aspect, a method comprises reducing a phase difference between a first image and a second image in a portion of a frame time of the 3-dimensional video display. The method also comprises redistributing respective bit sequences of at least portions of the first image and the second image by respective amounts arranged to effect the reduction of the phase difference between the first image and the second image. The method also comprises displaying the redistributed respective bit sequences of the portions of the first image and the second image during the frame time of the 3-dimensional video display.

  • Publication number: 20080247032
    Abstract: In display systems employing spatial light modulators, the OFF-state light from OFF-state pixels of the spatial light modulator can be captured and directed back to the pixels of the spatial light modulator so as to recycle the OFF-state light in the display system. Bitplanes derived from the desired image to be produced are calibrated to include the recycled off-state light to properly produce the desired image using the display system.

  • Patent number: 6906852
    Abstract: A method and system for providing a dithered image is provided. In one embodiment, a projector system for providing a dithered image includes a light source comprising a first and a second light emitting diode (LED). The first LED is operable to transmit a first light beam at a first peak wavelength. The second LED is operable to transmit a second light beam at a second peak wavelength. The first peak wavelength is disparate from the second peak wavelength. A digital micromirror device (DMD) is operable to receive the first beam and the second beam and selectively pass a first portion of the first beam and a second portion of the second beam along a projection path. A dichroic reflector operable to receive the first portion and the second portion, passively pass the first portion along the projection path, and substantially reflect the second portion within a wavelength range.
