  • Patent number: 10846917
    Abstract: The evaluation of multiple virtual camera representations at the same point-of-view within a three-dimensional environment without recalculating a light travel transform that represents how light travels and reflects within the three-dimensional environment. These virtual camera representations may include a light capture transform that represents a transform from camera input to camera output. The virtual camera representation may also include a vision algorithm for interpreting the camera output. Thus, different virtual camera representations at the same point-of-view may be used to obtain a variety of representations of the three-dimensional environment at the same point-of-view.

The varifocal element adjusts the focal length of the optics block so the optics block is focused at the plane of focus, which keeps the user's eyes in a zone of comfort as vergence and accommodation change. Based on the plane of focus, the virtual reality headset may provide depth cues, such as depth of field blur, to planes in the virtual scene deeper in the user's field of view than the plane of focus.

    Abstract: A projector includes a liquid crystal panel, an optical path shifting element which is capable of changing the optical path of light emitted from the liquid crystal panel, and an image processing unit. The optical path shifting element performs pixel shift such that light reaches different positions of a display screen in respective first to fourth unit periods acquired by dividing one frame into four parts. The image processing unit includes a conversion unit which converts a high resolution image signal into a low resolution image signal, and generates an output image signal by performing an overdrive process on the low resolution image signal according to a pixel shift state.

  • Patent number: 9633263
    Abstract: An approach for re-identifying an object in a first test image is presented. Brightness transfer functions (BTFs) between respective pairs of training images are determined. Respective similarity measures are determined between the first test image and each of the training images captured by the first camera (first training images). A weighted brightness transfer function (WBTF) is determined by combining the BTFs weighted by weights of the first training images. The weights are based on the similarity measures. The first test image is transformed by the WBTF to better match one of the training images captured by the second camera. Another test image, captured by the second camera, is identified because it is closer in appearance to the transformed test image than other test images captured by the second camera. An object in the identified test image is a re-identification of the object in the first test image.

  • Patent number: 9626770
    Abstract: A novel method of using optical flow algorithm that maximizes the benefit of optical flow synthetic frames while minimizing the associated computation cost is provided. When using optical flow to produce synthetic frames between two actual/recorded frames, the method computes a set of estimates of optical flows (or a flow estimate) between the two frames. These flow estimates are then used to compute all synthetic frames that are needed between the two actual frames by interpolation, which creates each synthetic frame based on its temporal distances from the pair of actual frames.

  • Patent number: 9578295
    Abstract: A method of displaying an image using at least a first projector and a second projector includes projecting a calibration pattern using the first projector, the calibration pattern being embedded in a first portion of an image projected by the first projector. The method determines a contribution of the second projector to projecting a second portion of the image to an overlap area, the overlap area having a contribution from the first and second projectors, wherein the contribution is an intensity of a color channel. The determined contribution of the second projector to the overlap area is modified to allow the calibration pattern of the first projector to be detectable to a capture device, the modification having a pattern corresponding to the calibration pattern. The image is then displayed using the first projector and the modified contribution of the second projector.
