Dual-Tap Pipelined-Code-Memory Coded-Exposure-Pixel CMOS Image Sensor for Multi-Exposure Single-Frame Computational Imaging

📋 论文概要

针对计算摄影应用对像素级曝光可编程性的需求，提出了一种双抽头流水线代码存储器编码曝光像素CMOS图像传感器。该传感器能够在单帧内实现多次编码曝光，支持多曝光单帧计算成像。

💡 主要创新点

• 提出双抽头像素结构，支持同时或顺序读取多个曝光信号。
• 集成流水线代码存储器于像素内，实现像素级编程化曝光时序。
• 实现单帧多曝光编码，无需多帧合成即可完成计算成像。

Unlike conventional cameras, which record all light incident onto a pixel, the emerging class of codedexposure-pixel (CEP) cameras can be programmed to selectively detect only some of that light [1] or, better, sort all of the light [2,3], depending on the pixel code. In conjunction with a concurrently coded illumination, this enables a wide range of new coded multi-exposure single-readout-frame imaging capabilities at video
