Abstract: A camera system captures an image in a source aspect ratio and applies a transformation to the input image to scale and warp the image to generate an output image having a target aspect ratio different than the source aspect ratio. The output image has the same field of view as the input image, maintains image resolution, and limits distortion to levels that do not substantially affect the viewing experience. In one embodiment, the output image is non-linearly warped relative to the input image such that a distortion in the output image relative to the input image is greater in a corner region of the output image than a center region of the output image.

Abstract: Disclosed is an electronically controlled camera iris device. The camera iris device may include a transparent conductor layer supplying an input voltage controlling the diameter of the aperture, a transparent resistance layer providing different voltages in different regions varying based on the distance from a center point, and a diaphragm layer that can be independently controlled in different regions to block or transmit light incident on the diaphragm layer when corresponding control voltages are applied on the diaphragm layer. The camera iris device can be configured to have a desired diameter by controlling a first region of the diaphragm layer to transmit the light and a second region of the diaphragm layer outside of the first region to block the light. The diaphragm layer may include a Bragg grating layer or an Electrochromic layer.

Abstract: A camera system includes a camera and an underwater housing. The underwater housing, when submerged underwater, causes refraction of light entering the camera, thereby affecting focus. The camera includes a lens assembly adjustable between a first secured position at a first distance from an image sensor to enable the camera to capture images that are in focus when the camera is outside of water. The lens assembly is adjustable to a second secured position at a second distance from the image sensor to enable the camera to capture images that are in focus when the camera operates within the underwater housing and submerged under water.

Abstract: A camera system includes an image sensor assembly and a tunable optical element. The tunable optical element is a gradient index (GRIN) lens created from a polymer dispersed liquid crystal and a coupled control element. The GRIN lens is tunable by applying an electric field to the optical element via a control element. The control element applies a voltage differential to the optical element inducing an electric field which changes the polarization of the PDLC within the optical element. The electrodes of the control element can include sheet resistors with a radially dependent voltage drop. The refractive index of the GRIN lens is dependent on the polarization of the liquid crystals within the optical element. Applying the electric field to the tunable element changes the optical properties of the grating.

Abstract: A camera is configured with multiple microphones to reduce wind noise in audio data collected by the camera. The camera receives motion data, which may comprise data indicating acceleration of the camera, a plurality of video frames received by the camera, or a background level of noise associated with one or more microphones configured on the camera. The camera determines a motion vector from the motion data. The motion vector is parallel to the direction of motion of the camera. The camera selects a subset of one or more microphones in the direction of the motion vector. By recording audio data using the one or more selected microphones, the camera reduces wind noise in the audio data.

Abstract: A content visualization system generates visual content for a visualization device based on visual content of a live event. The content visualization system collects visual content and source perspective data from visual content sources. The visualization device requests visual content from the content visualization system by providing device perspective data to the content visualization system. The content visualization system generates visual content for the visualization device based on the visual content from the visual content sources, the source perspective data, and the device perspective data. The content visualization system can determine visual content that is relevant to the device perspective by identifying source perspectives that overlap with the device perspective. The content visualization system generates visual content for the visualization device based on the identified visual content. The content visualization system can generate composited or non-composited visual content, based on the similarity of the source perspectives to the device perspective.

Abstract: A positioning system is designed to align a lens barrel with a sensor assembly. A first end of a lens barrel includes ridges along an edge. The sensor assembly includes a recessed channel with reciprocal ridges for mating with the ridges of the lens barrel. The sensor assembly also includes a plurality of shim platforms structured, each structured to position a wedge shaped shim, the wedge shaped shim including a flat bottom to slide on the shim platform and raise or lower the lens barrel relative to the reciprocal ridges on which the lens barrel rests.

Abstract: A visualization device allows a user to be immersed in visual content by projecting the visual content to the user. A projection element is positioned such that visual content projected from the projection element is reflected off of a mirror, which is angled such that the reflected projection is reflected onto a lens doublet. The lens doublet is angled such that the visual content projection reflected onto the lens doublet is partially reflected toward the user. In addition, an electrochromic slab can be controlled to allow configurable amounts of ambient light into the visualization device. If the electrochromic slab is configured such that no ambient light is allowed into the visualization device, the user is only able to see the visual content projected by the display device. The electrochromic slab can also be configured to allow some or all ambient light to travel into the visualization device.

Abstract: An image sensor of a camera system captures an image over an image capture interval of time, and waits a blanking interval of time before capturing an additional image. The captured image is provided to a frame controller, and is buffered until an image signal processor accesses the captured image. The image signal processor processes the accessed image over an image processing interval of time, producing a processed image. The image processing interval of time is selected to be greater than the image capture interval of time, but less than the sum of the image capture interval of time and the blanking interval of time. By reducing the image capture interval of time but maintaining an image processing interval of time, rolling shutter artifacts are beneficially reduced without increasing the processing resources or power required by the image signal processor to process the image.

Abstract: An image capture accelerator performs accelerated processing of image data. In one embodiment, the image capture accelerator includes accelerator circuitry including a pre-processing engine and a compression engine. The pre-processing engine is configured to perform accelerated processing on received image data, and the compression engine is configured to compress processed image data received from the pre-processing engine. In one embodiment, the image capture accelerator further includes a demultiplexer configured to receive image data captured by an image sensor array implemented within, for example, an image sensor chip. The demultiplexer may output the received image data to an image signal processor when the image data is captured by the image sensor array in a standard capture mode, and may output the received image data to the accelerator circuitry when the image data is captured by the image sensor array in an accelerated capture mode.
