Abstract

Integration-time based. time-domain computation provides an area-efficient way to process image information by directly handling photo-created charge during photo-sensing. We have fabricated and tested two integration-time based, time-domain computational image sensors. The first is a multi-integration time photo-receptor which uses different integration periods depending on light intensity. It exhibits a dynamic range for light intcnsity 128 times larger than that of a single integration period photoreceptor. The second is a CCD-based range-finding sensor which exploits two charge packcts for light integration and detects the delay of the receiving light pulses. It has detected 15 cm distance differences.
