Indirect time-of-flight sensor with parallel pixel structure

A sensor includes a plurality of pixels, each pixel having a dedicated computing circuit located within a computing layer. The plurality of pixels includes a first group of pixels and a second group of pixels. The first group of pixels is configured to detect light having a first modulation frequency from the local region. The second group of pixels is configured to detect light having a second modulation frequency from the local region. A computing layer is positioned below the plurality of pixels, and the computing layer includes computing circuitry for each of the plurality of pixels. The computational layer is configured to determine depth information for the local region using an indirect time-of-flight technique and one or both of the detected light having the first modulation frequency and the detected light having the second modulation frequency. 一种传感器包括多个像素，每个像素具有位于计算层内的专用计算电路。该多个像素包括第一组像素和第二组像素。第一组像素被配置为检测来自局部区域的具有第一调制频率的光。第二组像素被配置为检测来自该局部区域的具有第二调制频率的光。计算层被定位在该多个像素下方，并且该计算层包括用于该多个像素中的每个像素的计算电路。计算层被配
