What kind of camera is cdd?

CDD camera refers to a digital camera using CCD technology.

CCD is the abbreviation of charge coupled device. This technology can change light into charge, store charge and transfer charge, and make the voltage change. This camera has the characteristics of small size, light weight, no influence of magnetic field, and resistance to vibration and impact. However, this technology has been gradually eliminated, and now CMOS sensors are widely used in digital cameras.

CCD sensors can provide high-resolution images, usually higher than CMOS sensors. The noise generated by CCD sensor is relatively low, which means that the image quality is clearer and purer. CCD sensor can provide faster data reading speed, which is suitable for high-speed shooting and continuous shooting. Because of the high manufacturing cost of CCD sensor, digital cameras using this technology are usually more expensive than those using CMOS sensors.

Other types of cameras

1. Film camera: A film camera uses silver salt (mainly silver bromide AgBr) photosensitive material attached to a plastic film as a carrier. After shooting, the film has to be developed to get photos, so the film camera can't directly see the shooting effect and can't delete photos.

2. SLR camera: SLR camera is a camera with detachable lens. The advantage of SLR camera is that it can change different lenses according to different shooting needs and get different shooting effects.

3. High-speed camera: A high-speed camera is a camera that can take photos or videos at a very high speed. High-speed cameras are usually used to shoot fast-moving objects or record short-lived events.

4. Movie camera: A movie camera is a camera used to shoot movies or other videos. Cinematograph has a high resolution, usually higher than ordinary digital cameras, and can shoot high-definition videos.
