Abstract

In this article, we present a CMOS image sen- sor (CIS) for coded-exposure-based compressive focal-stack imag- ing. The proposed CIS has a pixel design, which includes two capacitive trans-impedance ampliﬁers (CTIAs) and a static random access memory (SRAM), and is capable of per-frame exposure encoding with adjustable spatiotemporal resolutions. A proof-of-concept CIS prototype with a 192 × 192 pixel array is designed and fabricated in a 0.13- µm CMOS process with a pixel size of 12.6 × 12.6 µm
