A CMOS smart image sensor LSI for focal-plane compression

Abstract

A CMOS smart image sensor LSI with video compression is presented. The proposed on-sensor compression scheme using an analog 2-D DCT processor is particularly useful to achieve low-power one-chip digital camera. A prototype image sensor LSI has been developed using 0.35 /spl mu/m double polysilicon, triple metal CMOS technology. Image coding using the implemented LSI has been demonstrated.
