What is a DC lens?

DC is the abbreviation of Digital Camera. Cameras with CCD and COMS as photosensitive elements can be called DC, which is "digital camera".

Early products As early as the 1960s, we began the research and development of CCD chips, developed digital cameras for the aerospace industry, and sent aerospace photos from space to the ground through satellite systems.

Digital cameras developed greatly in 1998. In 1998, Fujifilm launched the first million-level (1.5 million pixels) NEPIX700 digital camera, the lightest, smallest and most popular digital camera; Canon and Kodak cooperated to develop the first Digital SLR cameras EOSD2000 and EOSD6000 equipped with LCD monitors.

Extended information

Working principle

Digital cameras are optical, mechanical and electronic products. It integrates components such as conversion, storage and transmission of image information, and has the characteristics of digital access mode, interactive processing with computers and real-time shooting.

Light enters the camera through the lens or lens group, and is converted into digital signals through the imaging element. The digital signals are stored in the storage device through the image computing chip.

The imaging element of a digital camera is CCD or CMOS. The characteristic of this imaging element is that when light passes through, it can be converted into electronic signals according to the difference in light. Digital cameras first appeared in the United States. More than 20 years ago, the United States used them to transmit photos to the ground through satellites. Later, digital photography was converted to civilian use and its application scope continued to expand.
