Abstract: Described are imaging systems that employ diffractive structures as focusing optics optimized to detect visual edges (e.g., slits or bars). The diffractive structures produce edge responses that are relatively insensitive to wavelength, and can thus be used to precisely measure edge position for panchromatic sources over a wide angle of view. Simple image processing can improve measurement precision. Field-angle measurements can be made without the aid of lenses, or the concomitant cost, bulk, and complexity.
Abstract translation: 描述了采用衍射结构作为优化用于检测视觉边缘（例如，狭缝或条）的聚焦光学元件的成像系统。 衍射结构产生对波长相对不敏感的边缘响应，因此可以用于在宽视角上精确测量全色光源的边缘位置。 简单的图像处理可以提高测量精度。 场角测量可以在没有镜头的帮助下进行，或伴随的成本，体积和复杂性。

Abstract: Pixel circuits in an image sensor are sampled repetitively during an image frame period. At each sampling, a signal indicative of the photocharge integrated by a pixel circuit since last reset is compared to a threshold. If the integrated photocharge signal has not reached the threshold, the pixel circuit is permitted to continue integrating photocharge. If the integrated photocharge signal has reached the threshold, the pixel circuit is reset to remove integrated photocharge and photocharge integration for that pixel circuit is restarted. A corresponding pixel circuit value is recorded for the reset pixel circuit.
Abstract translation: 图像传感器中的像素电路在图像帧周期期间重复采样。 在每次采样时，将与上一次复位后的像素电路集成的光电荷的信号与阈值进行比较。 如果集成光电荷信号尚未达到阈值，则允许像素电路继续积分光电荷。 如果积分的光电荷信号已经达到阈值，则像素电路被复位以去除集成的光电荷并且该像素电路的光电荷积分被重新启动。 记录复位像素电路的对应像素电路值。

Abstract: An array of diffraction-pattern generators employ phase anti-symmetric gratings to projects near-field spatial modulations onto a closely spaced array of photoelements. Each generator in the array of generators produces point-spread functions with spatial frequencies and orientations of interest. The generators are arranged in an irregular mosaic with little or no short-range repetition. Diverse generators are shaped and placed with some irregularity to reduce or eliminate spatially periodic replication of ambiguities to facilitate imaging of nearby scenes.

Abstract: In an integrated-circuit image sensor, binary sample values are read out from an array of pixels after successive sampling intervals that collectively span an image exposure interval and include at least two sampling intervals of unequal duration. Each pixel of the array is conditionally reset after each of the successive sampling intervals according to whether the pixel yields a binary sample in a first state or a second state.
Abstract translation: 在集成电路图像传感器中，在连续的采样间隔之后从像素阵列中读出二进制采样值，该采样间隔共同跨越图像曝光间隔并且包括至少两个不等长度的采样间隔。 根据该像素是否产生处于第一状态或第二状态的二进制样本，阵列的每个像素在每个连续采样间隔之后有条件地重置。

Abstract: A sensing device projects near-field spatial modulations onto a closely spaced photodetector array. Due to physical properties of the grating, the point-spread response distributes spatial modulations over a relatively large area on the array. The spatial modulations are captured by the array, and photographs and other image information can be extracted from the resultant data. An image-change detector incorporating such a sensing device uses very little power because only a small number of active pixels are required to cover a visual field.
