A 1/4-inch 3.9Mpixel Low-Power Event-Driven Back-Illuminated Stacked CMOS Image Sensor

📋 论文概要

本文提出了一款1/4英寸、3.9百万像素的低功耗事件驱动背照式堆叠CMOS图像传感器，旨在满足智能家居摄像头等无线产品对小尺寸和长电池寿命的需求。通过事件驱动架构和背照式堆叠技术，实现了低功耗和高像素密度。

💡 主要创新点

• 采用事件驱动架构，仅在检测到场景变化时输出数据，大幅降低功耗。
• 结合背照式（BSI）和堆叠（Stacked）技术，在1/4英寸光学格式下实现3.9Mpixel高分辨率。

Small size, extended battery life, transparent machine interfaces: all these are required of the camera system in these applications. These applications, in battery-limited environments, can profit from an event-driven approach for moving-object detection. This paper presents a 1/4-inch 3.9Mpixel low-power event-driven (ED) back-illuminated stacked CMOS image sensor (CIS) deployed with a pixel readout
