Abstract

CMOS image sensors are capable of very high-speed non-destructive readout, enabling many novel applications. To explore such applications, we designed and prototyped an experimental high speed imaging system based on a CMOS digital pixel sensor (DPS). The experimental system comprises a PCB that has the DPS chip interfaced to a PC via three I/O cards supported by an easy to use software environment. The system is capable of image acquisition at rates of up to 1,400 frames/sec. After describing the DPS chip and experimental imaging system,we present two applications: dynamic range extension and optical flow estimation. These applications rely on the DPS´s ability to perform non-destructive readout of multiple frames at high-speed.
