Abstract: Signals representative of total photocharge integrated within respective image-sensor pixels are read out of the pixels after a first exposure interval that constitutes a first fraction of a frame interval. Signals in excess of a threshold level are read out of the pixels after an ensuing second exposure interval that constitutes a second fraction of the frame interval, leaving residual photocharge within the pixels. After a third exposure interval that constitutes a third fraction of the frame interval, signals representative of a combination of at least the residual photocharge and photocharge integrated within the pixels during the third exposure interval are read out of the pixels.

Abstract: An imaging system includes multiple diffractive optical gratings disposed over a two-dimensional array of photosensitive pixels. The different gratings present different patterns and features that are tailored to produce point-spread responses that emphasize different properties of an imaged scene. The different responses are captured by the pixels, and data captured from the responses can be used separately or together to analyze aspects of the scene. The imaging systems can include circuitry to analyze the image data, and to support modes that select between point-spread responses, selections of the pixels, and algorithms for analyzing image data.

Abstract translation: 在构成帧间隔的第一分数的第一曝光间隔之后，从像素中读出代表在相应图像传感器像素内的总光电荷的代表信号。 在构成帧间隔的第二部分的随后的第二曝光间隔之后，从像素中读出超过阈值电平的信号，在像素内留下残余光电荷。 在构成帧间隔的第三分数的第三曝光间隔之后，从像素中读出表示在第三曝光间隔期间集成在像素内的至少残留光电荷和光电荷的组合的信号。

Abstract: An optical smart sensor combines a phase grating with a rolling shutting to distinguish between modulated point sources. Employing a phase grating in lieu of a lens dramatically reduces size and cost, while using timing information inherent to imaging techniques that used a rolling shutter allows the smart sensor to distinguish point sources quickly and easily using a single frame of image data.
