One of the most dramatic demonstrations of the continuing advancement in VLSI has been the solid-state image sensor. Since the first array demonstration in 1967, the increase in pixel density in image sensors has matched the increase in cell density in dynamic memories. Today, image sensors with densities of 360,000 elements are available for consumer applications, and sensors with well over a million elements have been developed for government and scientific applications. Although electronic imaging has dominated the commercial and government market for many years, widespread application in consumer products has been limited by the high cost and low resolution of solid-state sensors as compared to vidicon-type tubes. Now, however, the cost of image sensors for television applications has fallen to a point at which it is attractive to design consumer products such as video cameras using solid-state image sensors. As a result, image sensors have entered the consumer marketplace as well. We discuss some of the advances made at Eastman Kodak Company in two areas: very high-speed image sensors and very high-density color image sensors. A brief introduction to image sensor architecture is presented, followed by descriptions of a 2000-frame/second sensor for high-frame-rate imaging and a 360,000-pixel color sensor for imaging photographic negatives.
