What is A 51-PJ Pixel 33.7-DB PSNR 4 Compressive CMOS Image Sensor With Column-Parallel Single-Shot Compressive Sensing about?

This article presents a CMOS image sensor with column-parallel single-shot compressive sensing, achieving an energy efficiency of 51 pJ/pixel and high image quality (PSNR > 33.7 dB). The proposed design utilizes a sparse pseudo-diagonal encoding matrix and a switched-capacitor multiplier, enabling data compression before pixel digitization, which significantly reduces power consumption. The prototype demonstrates over 5× improvement in energy efficiency compared to previous CS image sensors, making it suita
