Abstract: For an example method of reducing diffraction artifacts in a displayed image from a digital image projection system, a digital controller is coupled to a spatial light modulator. The spatial light modulator includes a two dimensional array of pixels. The method includes receiving signals containing pixel image data and processing the pixel image data to determine a desired gray scale for a pixel. The desired gray scale is compared to achievable gray scales of the digital image projection system. An upper bounding achievable gray scale is determined, and a lower bounding achievable gray scale is determined. Also, a dithering percentage for the desired gray scale is determined. The method chooses one of the upper bounding achievable gray scale and the lower bounding achievable gray scale. Also, a modified lower bounding gray scale is chosen to reduce the dithering percentage.

Abstract: In a method of image compression, a processor computes a palette for a block of pixels, the palette having palette values; and the processor computes index values, where some index values map a pixel to a palette value and some index values map a pixel to a value that is between two palette values.

Abstract: A system for displaying a high resolution video image utilizing multiple spatial light modulators includes at least one illumination source configured to provide illumination to multiple spatial light modulators; a video data image processor coupled to receive video image data at a first visual resolution of X by Y pixels; and multiple spatial light modulators each having an image resolution lower than the first visual resolution, each configured to project an image sub-frame onto a focal plane using an image projection system; wherein the image projection system is configured to project a first sub-frame image of a first color portion while simultaneously projecting at least a second sub-frame image of a second color portion onto the focal plane, and the first and second sub-frame images are offset from one another, so that when viewed together a viewed image has at least the first visual resolution. Methods are disclosed.

Abstract: A method for managing motion includes dividing a time allocated to display of an image into a first interval and a second interval. The second interval is immediately subsequent to the first interval. An amount of light energy to be emitted at a pixel during the time is determined based on the image. A first portion of the light energy is generated at the pixel in the first interval. The first portion comprises as much of the light energy as is generatable in the first interval. A second portion of the light energy is generated at the pixel in the second interval based on the light energy generatable in the first interval being less than the amount of light energy to be emitted at the pixel during the time.

Abstract: In described examples, a system (e.g., a security system or a vehicle operator assistance system) is configured to configure a phased spatial light modulator (SLM) to generate a diffraction pattern. A coherent light source is optically coupled to direct coherent light upon the SLM. The SLM is configured to project diffracted coherent light toward a region of interest. An optical element is configured to focus the diffracted coherent light toward the at least one region of interest.

Abstract: A video display system is configured to receive a sequence of image frames. Each frame is divided into a set of blocks. A center of mass is calculated for each block in a first frame and is saved for all blocks in the first frame. A center of mass is calculated for each block in a second frame. Motion between the first frame and the second frame is detected by comparing the center of mass of each block in the second frame to the center of mass of the corresponding block in the first frame, in which a still block is detected when a corresponding block in the first frame and the second frame have a same center of mass, and in which motion in a block is detected when a corresponding block in the first frame and the second frame have a different center of mass.
