摘要： A system having a color filter having first and second segments. The first and second segments allow respective first and second wavelengths to pass through to a spatial light modulator. The first and second segments also reflect second and first wavelengths, respectively. The reflected first and second wavelengths are recycled and directed towards the color filter.

摘要： A system includes a display device configured to display frames of images, a memory coupled to the display device and configured to store image data representing a sequence of the frames, and a memory controller coupled to the memory. The memory controller is configured to split a frame in the sequence of frames into a slice count of frame slices according to an order of respective frame slice numbers, partition the memory into a number of buffer slices in an ordered sequence wherein the number of buffer slices is greater than or equal to the slice count, write each frame slice in the sequence of frames to a next free buffer slice in the ordered sequence of buffer slices, read each written frame slice to the display device to display the written frame slice with other displayed frame slices according to the order of the respective frame slice numbers, and return to a first buffer slice in the ordered sequence after writing a frame slice in a last buffer slice in the ordered sequence.

摘要： A method includes receiving, by a frame converter, a frame of pixel data and converting, by the frame converter, the frame to a first frame division unit. The method also includes receiving, by a translation circuit, a pixel coordinate and cropping and shifting, by the translation circuit, the first frame division unit based on the pixel coordinate, to produce a second frame division unit. Additionally, the method includes outputting, by the translation circuit, the second frame division unit.

摘要： A method includes projecting an image onto a projection surface through a projection lens of a projector, where the image comprises a fiducial marker. The method also includes capturing a point cloud of the fiducial marker with a camera, and generating a distortion map of projection lens distortion based at least in part on the point cloud. The method also includes generating a correction map for the projection lens, and applying the correction map to a video signal input to the projector.

摘要： A method includes rendering, by at least one processor, a first sub-frame of an image, where the first sub-frame includes a first subset of pixels of the image. The method includes displaying the first sub-frame on a display. The method also includes rendering, by the at least one processor, a second sub-frame of the image, where the second sub-frame includes a second subset of pixels of the image, and where the second sub-frame is shifted a half-pixel diagonally from the first sub-frame. The method also includes displaying the second sub-frame on the display after displaying the first sub-frame, where the display is optically shifted a half-pixel diagonally to display the second sub-frame.

摘要： An apparatus includes a parser configured to decimate a source image to produce a decimated image according to a pre-distortion geometry for the source image, and partition the decimated image into image portions according to a first clock rate. The apparatus includes warping engines coupled to the parser and configured to pre-distort, according to a second clock rate, respective image portions to produce respective pre-distorted image portions according to the pre-distortion geometry. The apparatus also includes a combiner coupled to the warping engines and configured to combine the pre-distorted image portions, according to the first clock rate, to form a pre-distorted image of the source image. The apparatus further includes a processor configured to process the pre-distorted image to produce a processed image for projection by a light modulator and one or more light sources.

摘要： A system includes a spatial light modulator (SLM) configured to project an image. The system also includes a controller coupled to the SLM. The controller is configured to receive the image and determine a brightness level of the image. The controller is also configured to enforce a brightness limit on the image responsive to the brightness level, to produce a reduced image. The controller is configured to instruct a display to display the reduced image.

摘要： An apparatus includes a first camera configured to capture a first image being displayed, a second camera configured to capture a second image being displayed, and a processor configured to generate a pair-wise homography transform for the first camera and the second camera, and map, based on the pair-wise homography transform, the second image from a second frame of reference of the second camera to a first frame of reference of the first camera. The processor is further configured to determine a first corrected quadrilateral for the first image and a second corrected quadrilateral for the second image in the first frame of reference, and project, based on the pair-wise homography transform, the second corrected quadrilateral from the first frame of reference to the second frame of reference. The quadrilaterals are then processed to warp respective images for geometric correction before projecting the images by respective projectors.
