What are the components of traditional cameras and digital cameras?

(aka: digital camera)

English full name: digital

camera

Called dc)

Digital camera is a kind of camera that uses electronic sensors to convert optical images into electronic data.

Different from the principle that ordinary cameras record images on film through the chemical changes of silver bromide, the sensors of digital cameras are light-induced charge-coupled -{zh-cn: devices; Zh-tw: Component }-(ccd) or complementary metal oxide semiconductor (cmos). Before an image is transmitted to a computer, it is usually stored in a digital storage device (usually using flash memory; Floppy disks and rewritable compact discs (cd-rw) are rarely used in digital camera equipment. [Edit this paragraph] Working principle

Digital camera is a product integrating optics, machinery and electronics. It integrates the conversion, storage and transmission of image information, and has the characteristics of digital access, interactive processing with computer and real-time shooting. Light enters the camera through a lens or lens group, and is converted into a digital signal through an imaging element, and the digital signal is stored in a storage device through an image operation chip.

The imaging element of digital camera is ccd or coms, which is characterized in that when light passes through it, it can be converted into electrical signals according to different light. Digital cameras first appeared in America. More than 20 years ago, the United States used it to transmit photos to the ground via satellite. Later, digital photography was converted to civilian use, and its application scope continued to expand.

Advantages:

1. You can see the picture immediately after taking a picture, which provides the possibility of remaking the dissatisfied work immediately and reduces the occurrence of regrets.

Just pay for those photos you want to develop, and other unnecessary photos can be deleted.

3. Color reproduction and color range no longer depend on the quality of the film.

4. Sensitivity is no longer fixed by film. The photoelectric conversion chip can provide a variety of sensitivity options.

Disadvantages:

1. Due to the conversion between imaging elements and image processing chips, the imaging quality is less layered than that of optical cameras.

2. Due to the different technologies of image processing chips from different manufacturers, the colors of the imaged photos are different from the real ones.

3. Due to the lack of core technology in China, the later use and maintenance costs are high.
