在过去几年中,人们一直期望CMOS(互补金属氧化物半导体)感光器件能够获得快速发展,但面对CCD(电荷耦合器件)器件的压倒性优势,这种技术却遇到了巨大的挑战,在数字相机领域中就是如此。 iSuppli预测全球CMOS市场将从2001年的1800万美元增长到2005年的7200万美元。同时,CCD的增长将相当缓慢,只是从2000年的4900万 In the past few years, people have been expecting rapid development of CMOS (Complementary Metal Oxide Semiconductor) light-sensing devices, but this technology presents a huge challenge in the face of the overwhelming advantages of CCD (Charge Coupled Device) devices. This is the case in the digital camera arena. iSuppli predicts the global CMOS market will grow from 18 million U.S. dollars in 2001 to 72 million U.S. dollars in 2005. At the same time, the growth of CCD will be rather slow, only 49 million from 2000
