Abstract: Panoramic imaging systems and techniques are disclosed. In one aspect, a technique for generating a stabilized panoramic video image output based on raw image data captured by a panoramic imaging system includes the steps of: receiving raw video images capturing by the panoramic imaging system which is integrated with a set of position sensors; receiving multiple sets of sensor signals acquired by the set of position sensors concurrently when the raw video images are being captured; processing the multiple sets of sensor signals to determine unwanted position changes of the panoramic imaging system when the raw video images are being capturing; and performing an image stabilization operation on the received raw video images to compensate for the effects of the unwanted position changes, thereby generating stabilized panoramic video images based on the raw video images.

Abstract: Panoramic three-dimensional (3D) imaging systems for capturing stereoscopic video images and presenting 3D video images to a viewer based on the captured stereoscopic video images are disclosed. In some embodiments, the described systems use a proposed parallax vector to encode captured stereoscopic video images in real-time when the raw video images are being captured. During panoramic video playback, the computed parallax vectors are used to reproduce stereoscopic video images based on the angle of view of an audience relative to a display screen before outputting the stereoscopic video images to the left and right eyes of the audience to create the realistic 3D experience.

Abstract: An omni-directional audio signal acquisition and playback system is disclosed. In some embodiments, the described system includes a set of microphones positioned substantially evenly with respect to a center of the audio signal acquisition environment, the set of microphones are configured to acquire multiple channels of omni-directional audio signals. The system further includes one or more processors configured to: determine current positions of both the left and the right ears of a viewer's head; identify a subset of microphones within the set of microphones which is closest to the current positions of the left and right ears of the viewer's head; and compute a left channel and a right channel of audio output signals using the omni-directional audio signals recorded by the identified subset of microphones. The system also includes a set of audio output devices configured to playback the left channel and the right channel of audio output signals for the left ear and the right ear of the viewer, respectively.

Abstract: Panoramic imaging systems and process for multiplexing a set of video signal inputs captured by a set of cameras in a panoramic imaging system into a single video signal output is disclosed. In some embodiments, the disclosed process receives a set of input image frames associated with the set of video signal inputs and temporarily stores the set of input image frames in a memory. Next, for each pair of image frames in the set of input image frames, the process iteratively processes each line in the pair of image frames to construct a portion of a video signal output frame. The process then combines portions of the video signal output frame to form a single composite output frame containing the image data of the set of input image frames.

Abstract: Panoramic imaging system and process for adjusting luminance levels of a set of video signals captured by a set of cameras in the panoramic imaging system is disclosed. In some embodiments, the disclosed panoramic imaging system includes a housing, the set of cameras and an integrated circuit (IC) chip coupled to the set of cameras and configured to adjust luminance levels of a set of video signals captured by the set of cameras, thereby enabling the set of cameras to capture the set of video signals having substantially the same luminance level. The panoramic imaging system further includes an image processor coupled to the IC chip and configured to receive the set of video signals having substantially the same luminance level and to post-process the set of video signals.

Abstract: Disclosed is a shallow trench isolation (STI) structure and methods of manufacturing the same. The methods eliminate the requirement for design size adjustments (DSA) in manufacturing the STI structure. Further disclosed is an STI trench liner and methods for the formation thereof by growing a thin oxide layer on shallow isolation trench surfaces while preventing oxide formation on adjacent nitride surfaces, followed by the deposition of, and oxide growth upon, a polysilicon layer.

Abstract: A trench structure in a wafer of semiconductor material and the method of forming the trench structure are described. The trench structure is formed on a semiconductor wafer that has a top surface of slow oxidization rate—slower than that of other major crystallographic planes of the semiconductor material. The trench is etched into the semiconductor wafer. The trench has substantially vertical trench-sidewalls near the top surface, the vertical trench-sidewalls near the top surface containing crystallographic plane that oxidizes at a rate comparable to that of the top surface. An insulating layer is grown on the top surface and on the trench-sidewalls and on corners where sidewall surfaces approach the top surface, the insulating layer at the corners being substantially thicker than at the sidewall adjacent to the corners. The difference in the oxide thickness is due to the faster oxidizing planes exposed at the corners. Finally, the trench is filled with a dielectric material.
