    摘要： A novel projection system includes first and second light sources (e.g., sets of lasers), a spatial light modulator (SLM) that receives light from the first light source, and a beam steering device that receives light from the second light source and steers the light to highlight regions of the SLM. The SLM then modulates the light from both light sources to generate a highlighted imaging beam which can then be projected on a viewing surface. The highlighted imaging beam can represent a highlighted 2D image or a highlighted left- or right-eye view of a 3D image. The projection system thus improves peak brightness in the displayed highlighted images without incorporating a separate highlight projector or other expensive equipment. Methods for highlighting projected images are also described.

    摘要： The disclosure features three-dimensional stereoscopic imaging systems and methods that include two image capture devices configured to obtain images of a scene, at least one display screen, and an electronic processor configured to: receive one or more images of the scene from the capture devices, where each of the one or more images includes a lateral dimension and a height; warp the one or more images along their respective lateral dimensions to at least partially correct for disparity distortions associated with displaying the one or more images on the at least one display screen; correct the one or more images by scaling the respective heights of the images along the lateral dimensions of the images so that the height of each image is the same along the images lateral dimension; and display the warped and corrected one or more images on the at least one display screen.

    摘要： Methods and systems for displaying full-color three-dimensional imagery are provided. A first color set, having a first color spectrum, is defined to include a first set of LEDs. The first color set is assigned to a first color-coded image perspective. A second color set, having a second color spectrum, is defined to include a second set of LEDs. The second color set is assigned to a second color-coded image perspective. The full-color three-dimensional imagery is caused by activating, alternatively, at least two LEDs of the first color set or the second color set and one LED of a remaining color set and displaying the three-dimensional image based on the first image perspective and the second image perspective.

    摘要： Shaped glasses have curved surface lenses and spectrally complementary filters disposed on the curved surface lenses configured to compensate for wavelength shifts occurring due to viewing angles and other sources. The spectrally complementary filters include guard bands to prevent crosstalk between spectrally complementary portions of a 3D image viewed through the shaped glasses. In one embodiment, the spectrally complementary filters are disposed on the curved lenses with increasing layer thickness towards edges of the lenses. The projected complementary images may also be pre-shifted to compensate for subsequent wavelength shifts occurring while viewing the images.
