From the passage we learn how a digital camera works with some principles and processes. [br] The great difference between CCD and CMOS is that CCD needs ADC while CMOS not.
选项
A、Y
B、N
C、NG
答案
A
解析
由题干CCD,CMOS和ADC可定位至第二个小标题下第三、四段。该部分主要介绍原理特点:CCD需要将采集到的模拟电荷转化成二进制信号,因而需要ADC;而CMOS每一个采样点都是用晶体管直接采集成数字信号,故不需要。由此可知题干陈述正确。
