    摘要： Systems and methods are described for defining a set of images based on captured images, receiving a viewing direction associated with a user of a virtual reality (VR) head mounted display, receiving an indication of a change in the viewing direction. The methods further include configuring, a re-projection of a portion of the set of images, the re-projection based at least in part on the changed viewing direction and a field of view associated with the captured images, and converting the portion from a spherical perspective projection into a planar perspective projection, rendering by the computing device and for display in the VR head mounted display, an updated view based on the re-projection, the updated view configured to correct distortion and provide stereo parallax in the portion, and providing, to the head mounted display, the updated view including a stereo panoramic scene corresponding to the changed viewing direction.

    摘要： A time of flight sensor includes control circuitry and a time of flight pixel array. The control circuitry is coupled to synchronously send a sync signal. The time of flight pixel array includes a plurality of time of flight pixel cells. Each one of the time of flight pixel cells includes a photosensor and a delay circuit. The photosensor is configured to generate an image signal in response to receiving photons from a light pulse reflected from an object. The delay circuit is coupled to generate a delayed sync signal in response to the sync signal. The delay circuit includes a delay transistor. The time of flight pixel array includes a transistor gradient where a transistor gate length of the delay transistor varies so that each of the time of flight pixel cells receive their respective delayed sync signal at a same time.

    摘要： A method and apparatus involves directing light captured within the field of view of the lens to an aperture plane of the lens, receiving the captured light at a spatial discriminator located proximate the aperture plane, the discriminator including a first portion disposed to transmit light having a first optical state through a first portion of the single imaging path and a second portion disposed to transmit light having a second optical state through a second portion of the single imaging path. The first and second portions of the single imaging path provide respective first and second perspective viewpoints within the field of view of the lens for forming respective first and second images at an image sensor disposed at an image plane of the lens. The first and second images together being operable to represent three dimensional spatial attributes of the objects.
