| 20110148742 | CONFIGURABLE IMAGING SYSTEM - A method for use in an imaging system having an image source and a plurality of microtile units for generating respective portions of the image is provided, each microtile unit including a self-contained screen and a rear projector for projecting the image on the screen, the method for at least one of self-aligning, colour matching and brightness matching the image portions across successive adjacent microtile units. The screen is over-scanned so that a portion of an edge of each image spills over onto a side wall of the microtile unit adjacent a further one of microtile units. Light from the image is permitted to spill through the side wall into the further microtile unit. The light is detected within the further microtile unit. The image is adjusted in response to detection of the light within the further microtile unit so as to at least one of align, color match and brightness match the image between the plurality of microtile units. | 06-23-2011 |
| 20110148741 | CONFIGURABLE IMAGING SYSTEM - An imaging system is provided. The imaging system comprises an image source providing a video data stream. The imaging system further comprises a plurality of microtile units for: generating respective portions of an image from the video data stream, each microtile unit connectable to a plurality of other microtile units in multiple geometrical configurations. Each microtile unit comprises circuitry for: communication with the plurality of other microtile units to control generation of each respective portion of the image; and sub-image capture from the video data stream. The imaging system further comprises a system control unit for: automatically detecting a configuration of connected microtile units to determine information indicating a portion of the image each individual microtile unit is to be responsible for; and relaying respective information comprising a respective portion of the image a respective microtile unit is to be responsible for to each the respective microtile unit in the sub-image capture. | 06-23-2011 |
| 20110032493 | SAFETY INTERLOCK SYSTEM FOR A PROJECTOR SYSTEM - A safety interlock system for a projector system is provided. The projector system has a lamp, a controller and ballast for powering the lamp upon receipt of a lamp enable signal from the controller. The projector system further has a safety inter-lock system for deactivating the lamp in the event the lamp is not properly installed. | 02-10-2011 |
| 20090002998 | Reflective iris - According to embodiments described in the specification, a reflective iris is described for concentrating collimated light emitted from a parabolic lamp, the parabolic lamp comprising a lamp aperture from which the collimated light is emitted. The reflective iris is comprised of a planar reflective element for reflecting the collimated light back towards the parabolic lamp, a shape of the planar reflective element being generally complementary to a shape of the lamp aperture; and an optical aperture through the planar reflective element, disposed around a perpendicular axis of the planar reflective element, for light to pass through the planar reflective element. When the reflective iris is axially aligned with the parabolic lamp, the collimated light is reflected from the planar reflective element back towards the parabolic lamp, for reflection back through the optical aperture. | 01-01-2009 |
| 20090002398 | Method and apparatus for scaling an image to produce a scaled image - According to embodiments described in the specification, a method, and apparatus for scaling an image to produce a scaled image is described, the image comprising an array of image pixels, and the scaled image comprising an array of scaled pixels. In a first step a map is created between the array of scaled pixels and the array of image pixels. In a second step, an energy parameter of each image pixel in the array of image pixels is determined. In a third step, a fraction of a given image pixel which overlaps a given scaled pixel in the array of scaled pixels is determined for each image pixel, in the array of image pixels. In a final step the energy parameter of the given image pixel is distributed between scaled pixels which overlap the given image pixel, the distributing based on the fraction, such that the energy parameter is conserved. | 01-01-2009 |
| 20080285087 | CONFIGURABLE IMAGING SYSTEM - An imaging system, comprising an image source and a plurality of microtile units for generating respective portions of an image, each microtile unit including a plurality of coupling mechanisms for connection to a plurality of other microtile units such that the microtile units may be arranged in multiple geometrical configurations, and each microtile unit including circuitry for communication with the other microtile units to control generation of each respective portion of the image. | 11-20-2008 |
| 20080284675 | CONFIGURABLE IMAGING SYSTEM - An imaging system, comprising an image source and a plurality of microtile units for generating respective portions of an image, each microtile unit including a plurality of coupling mechanisms for connection to a plurality of other microtile units such that the microtile units may be arranged in multiple geometrical configurations, and each microtile unit including circuitry for communication with the other microtile units to control generation of each respective portion of the image. | 11-20-2008 |
