Abstract

The document reflects upon the development and advancements in the field of image sensors, particularly centered around the transition from Charged-Coupled Devices (CCDs) to Complementary Metal-Oxide-Semiconductor (CMOS) image sensors over the past 25 years. The author, Eric R. Fossum, shares his personal experiences and insights on the technological evolutions and trends in the field, including his involvement in the transition to CMOS technology and his thoughts on future directions like Quanta Image Sensors (QIS).
