An 83dB-Dynamic-Range Single-Exposure Global-Shutter CMOS Image Sensor with In-Pixel Dual Storage make the photon-shot signal the dominant noise, the sum of CDS-readout and DRS-readout signals is used.

📋 论文概要

提出了一种单次曝光全局快门CMOS图像传感器，通过像素内双存储结构实现了83dB的动态范围，解决了卷帘快门对运动目标成像的失真问题。

💡 主要创新点

• 采用像素内双存储（In-Pixel Dual Storage）结构，在单次曝光中捕获高低增益信号，从而扩展动态范围至83dB。
• 实现全局快门（Global Shutter），消除了卷帘快门导致的运动伪影，适用于高速运动场景。

The need has consequently been felt for global-shutter CMOS image sensors. An in-pixel low-leakage analog memory is required to realize a global-shutter CMOS image sensor. A floating diffusion (FD) can be used as a storage node, but the readout signal is affected by the reset kT/C noise due to delta reset sampling (DRS) used instead of correlated double sampling (CDS) [1]. This is why global-shutter CMOS image sensors incorporate an additional in-pixel storage node
