A 3-Stacked Hybrid-Shutter CMOS Image Sensor with Switchable 1.2µm-Pitch 50Mpixel Rolling Shutter and 2.4µm-Pitch 12.5Mpixel Global Shutter Modes for Mobile Applications

📋 论文概要

本文提出了一种3层堆叠混合快门CMOS图像传感器，可在1.2µm像素间距50Mp卷帘快门和2.4µm像素间距12.5Mp全局快门之间切换，解决了高分辨率与高动态范围成像的兼容性问题。

💡 主要创新点

• 提出混合快门结构，通过像素合并实现卷帘快门与全局快门模式切换，兼顾高分辨率与高动态范围。
• 采用3层堆叠工艺，将像素层、存储层和逻辑层垂直集成，优化了像素面积和信号处理效率。

In addition, various efforts have been actively devoted to strengthen the functionality of image sensors through advanced stacking process technologies, e.g., rolling shutter (RS) CIS with event vision sensors (EVS) for enhancing imaging quality [2]. A global shutter (GS) CIS is an excellent alternative to overcome the limitations of conventional RS CISs. GS CISs for mobile applications can create value as follows: 1) GS
