数字相机技术与发展——数字成像技术进展(二)

The development of Digital Camera——Achievements of Digital Imaging Technology

数字相机技术属于数字成像动态获取(输入)技术的范畴。数字相机用CCD或CMOS图像传感器成像,涉及了图像压缩、存储、传输、输出等一系列关键技术。摄取连续图像成为数字摄像机,与网络相连可实时异地传输摄影图像。本文对数字相机发展进行了归纳,对其关键技术做了分析,对数字相机的几个发展趋势做出预测。

The digital camera(DC)is one kind of application in dynamic image acquisition/input technolegy.Usually,CCD is used in DC as the image sensor,but now the CMOS image sensor is also used in DC.A series of technology,such as image compress,memory,and image transfer,is involved in DC.In this paper,the developments of the DC and correlative pivotal technology are introduced.In addition,some trends of DC are predicted.
