DV的成像系统具有双重特性:一方面,DV同样属于一般物理光学成像器材,因此在原理和元件组成上,都与其他物理光学成像器材的通用特征相符合;另一方面,由于DV自身还需要顾及多种与它应用场合相关的特别要求,因此,它在普通物理光学成像器材的通用特性之外,还具备众多自身的特殊属性。例如:DV是一种偏重动态拍摄的摄影器材,所以,DV成像系统中的主要成像元件,会把重点放在画面的快速、准确记录上,而成像质量则可略居其次位。
DV imaging system has the dual characteristics: on the one hand, DV also belongs to the general physical optical imaging equipment, so the principle and component composition, and other physical optical imaging equipment common features consistent; the other hand, because DV itself also needs Aside from the many special requirements associated with its application, it has a number of its own special attributes in addition to the general characteristics of ordinary physical optical imaging equipment. For example, DV is a photographic equipment that emphasizes dynamic recording. Therefore, the main imaging elements in a DV imaging system will focus on the fast and accurate recording of the picture while the image quality may be slightly inferior.
