Which invention spurred the development of the digital camera? A) the digital single-lens reflex (DSLR)

B) the charge-coupled device

C) the analog video camera

D) the memory card

B) The charge-coupled device

Explanation:

Around 1964 the first CMOS (Complementary Metal Oxide Semiconductor) circuits were developed. This would be the "embryo" of the Charge-coupled Device (CCD), which equips current digital cameras and who is responsible for capturing images.

CMOS is a small circuit that uses very little energy and stores information such as date, time and system configuration parameters.  

The first CCD was developed in 1969 and it is still used today in many portable devices and computers.
