A trimodal microlens configuration is provided for the lenses in a microlens array utilized as a diffraction separator for generating separated bands of different color when the microlens array is provided with a collimated light source. To provide the trimodal functionality, each microlens is divided up into three segments, with the center segment providing a red, green, blue diffraction pattern, with the left segment providing a blue, red, green diffraction pattern, and with the right segment providing a green, blue, red diffraction pattern. This pattern is directed towards an adjacent liquid crystal color display in which its sub-pixels are arranged red, green, blue, with the green sub-pixel aligned with the center segment of the corresponding lens. The result of the trimodal lens is an overlapping of illumination for each of the sub-pixels in that the lens segment aligned with the particular colored sub-pixel provides one third of the light, with the other two thirds of the light being provided by adjacent segments of the lenses in the microlens array. The result of the overlapping illumination of the sub-pixels is that the viewing direction is symmetric about a normal to the array which makes the design of the diffuser used with liquid crystal displays quite simple and eliminates off-axis dead zones.

A system is provided for increasing the brightness and color saturation of a liquid crystal display to permit direct sunlight viewing which includes the utilization of an array of diffractive color separation microlenses which serve both to spatially separate incoming white light into red, green and blue bands which do not overlap and to focus the bands onto a subpixel matrix such that each of the sub-pixels is illuminated with only one color. The diffractive color separation is made possible through the utilization of the iterative genetic algorithm which specifies the stepped surface of the lens that provide for exceptionally fine color separation. In one embodiment the genetic algorithm is applied iteratively to define the optimal stepped surfaces which are utilized to focus the various colors at different positions at the focal plane of the lens. The subject system improves the overall transmission efficiency of 5% for a standard liquid crystal display to in excess of 30% overall efficiency. This results in lower power requirements or alternatively a brighter display such that the displays are sunlight viewable and have application in lap top computers, cockpit displays, automobile instrument displays, ATM displays, projection displays, equipment displays, and in general any display of a color LCD nature which is to be viewed in direct sunlight.

A process, known as the Hick's Probabilistic Data Association Algorithm, correlates sensor measurement to target tracks under condition in which there are numerous false measurements. It accomplishes this by forming multiple hypotheses and computing a probabilistic score for each. The hypothesis with the high score is then used as a probability vector to update each target's track. The result is accomplished by combining the attributes of Joint Probabilistic Data Association (JPDA) and Nearest Neighbor Standard Filter (NNSF). This combination provides an improved algorithm which yields improved performance ever both prior art methods under high clutter conditions with crossing targets.

Often when there is a glare on a display screen the user may be able to mitigate the glare by tilting or otherwise moving the screen or changing their viewing position. However, when driving a car there are limited options for overcoming glares on the dashboard, especially when you are driving for a long distance in the same direction. Embodiments are directed to eliminating such glare. Other embodiments are related to mixed reality (MR) and filling in occluded areas.

Systems, apparatuses and methods may include a source device that generates a scene change notification in response to a movement of a camera, modifies an encoding scheme associated with the video content captured by the camera in response to the scene change notification, identifies a full-frame difference threshold, wherein scene analysis information includes frame difference data, and compares the frame difference data to an intermediate threshold that is less than the full-frame difference threshold, wherein the scene change notification is generated when the frame difference data exceeds the intermediate threshold. A sink device may obtain transport quality data associated with video content, modify an output parameter of a display based on the transport quality data, determine a view perspective of a still image containing a plurality of image slices, retrieve only a subset of the plurality of image slices based on the view perspective and decode the retrieved subset.

Systems, devices, and techniques related to matching features between a dynamic vision sensor and one or both of a dynamic projector or another dynamic vision sensor are discussed. Such techniques include casting a light pattern with projected features having differing temporal characteristics onto a scene and determining the correspondence(s) based on matching changes in detected luminance and temporal characteristics of the projected features.

Systems, apparatuses and methods may provide for technology to improve user experience when viewing simulated 3D objects on a display. Head and upper-body movements may be tracked and recognized as gestures to alter the displayed viewing angle. The technology provides for a very natural way to look around, under, or over objects.
