Abstract: Aspects of the present disclosure relate to an image sensor. An example apparatus includes an image sensor including one or more pixels. Each pixel of the one or more pixels includes a photodetector, and the photodetector includes a photosensitive surface including germanium. In some implementations, the photodetector includes a photodiode including an intrinsic silicon layer doped with germanium or including germanium crystals. The intrinsic layer may be between a p− layer and an n− layer not including germanium. The intrinsic layer may be configured to absorb photons of the light received at the intrinsic layer. The light may include one or more reflections of an emitted light for active depth sensing. For example, the emitted light may be frequency modulated and having a first wavelength for indirect time-of-flight depth sensing. Sampling circuits may generate voltages indicating a phase difference between the emitted light and a reflection of the emitted light.

Abstract: This disclosure provides systems, methods, and apparatuses for sensing a scene. In one aspect, a device may illuminate the scene using a sequence of two or more periods. Each period may include a transmission portion during which a plurality of light pulses are emitted onto the scene. Each period may include a non-transmission portion corresponding to an absence of emitted light. The device may receive, during each transmission portion, a plurality of light pulses reflected from the scene. The device may continuously accumulate photoelectric charge indicative of the received light pulses during an entirety of the sequence. The device may transfer the accumulated photoelectric charge to a readout circuit after an end of the sequence.

Abstract: Certain aspects relate to systems and techniques for full well capacity extension. For example, a storage capacitor included in the pixel readout architecture can enable multiple charge dumps from a pixel in the analog domain, extending the full well capacity of the pixel. Further, multiple reads can be integrated in the digital domain using a memory, for example DRAM, in communication with the pixel readout architecture. This also can effectively multiply a small pixel's full well capacity. In some examples, multiple reads in the digital domain can be used to reduce, eliminate, or compensate for kTC noise in the pixel readout architecture.

Abstract: Exemplary embodiments are directed to configurable demodulation of image data produced by an image sensor. In some aspects, a method includes receiving information indicating a configuration of the image sensor. In some aspects, the information may indicate a configuration of sensor elements and/or corresponding color filters for the sensor elements. A modulation function may then be generated based on the information. In some aspects, the method also includes demodulating the image data based on the generated modulation function to determine chrominance and luminance components of the image data, and generating the second image based on the determined chrominance and luminance components.

Abstract: Structured light active sensing systems transmit and receive spatial codes to generate depth maps. Spatial codes can't be repeated within a disparity range if they are to be uniquely identified. This results in large numbers of codes for single transmitter/single receiver systems, because reflected ray traces from two object locations may be focused onto the same location of the receiver sensor, making it impossible to determine which object location reflected the code. However, the original code location may be uniquely identified because ray traces from the two object locations that focus onto the same location of the first receiver sensor may focus onto different locations on the second receiver sensor. Described herein are active sensing systems and methods that use two receivers to uniquely identify original code positions and allow for greater code reuse.
Abstract translation: 结构化的光主动感测系统发送和接收空间码以生成深度图。 如果要独特地识别空间代码，则不能在差异范围内重复。 这导致单个发射器/单个接收器系统的大量代码，因为来自两个对象位置的反射光线迹可能聚焦到接收器传感器的相同位置，使得不可能确定哪个对象位置反映了代码。 然而，由于来自聚焦在第一接收器传感器的相同位置上的两个对象位置的射线轨迹可以聚焦到第二接收器传感器上的不同位置，所以可以唯一地识别原始代码位置。 这里描述的是使用两个接收器唯一地识别原始代码位置并允许更大代码重用的主动感测系统和方法。

Abstract: Aspects relate to an array camera exhibiting little or no parallax artifacts in captured images. For example, the planes of the central mirror prism of the array camera can intersect at an apex defining the vertical axis of symmetry of the system. The apex can serve as a point of intersection for the optical axes of the sensors in the array. Each sensor in the array “sees” a portion of the image scene using a corresponding facet of the central mirror prism, and accordingly each individual sensor/mirror pair represents only a sub-aperture of the total array camera. The complete array camera has a synthetic aperture generated based on the sum of all individual aperture rays.

Abstract: Systems and methods for depth enhanced and content aware video stabilization are disclosed. In one aspect, the method identifies keypoints in images, each keypoint corresponding to a feature. The method then estimates the depth of each keypoint, where depth is the distance from the feature to the camera. The method selects keypoints of within a depth tolerance. The method determines camera positions based on the selected keypoints, each camera position representing the position of the camera when the camera captured one of the images. The method determines a first trajectory of camera positions based on the camera positions, and generates a second trajectory of camera positions based on the first trajectory and adjusted camera positions. The method generates adjusted images by adjusting the images based on the second trajectory of camera positions.
