Why is CCD camera popular again?

Because the photos taken by ccd photo album can adjust the tone of CCD film, the old digital photos can be retouched.

As a photographic equipment, mobile phones are on the rise, and the differentiation of cameras of various brands is getting smaller and smaller. The camera industry is more boring than ever. ?

Excessive redundancy is no longer the selling point of merchants, and various symbolic goods have become new sales growth points. CCD Shintoism claims that by reshaping the Millennium concept and retouching the old digital photos, the old digital cameras have a unique CCD flavor-although this effect is not significant, it is convincing.

People live in a long cycle: the progress of science and technology makes people try their best to improve efficiency, on the other hand, people take pains to create obstacles for themselves and constantly pick up and simulate backward things. People miss the era when cameras were as full of flowers and imagination as mobile phones.

Principle and application of CCD camera;

Lattice pixel CCD is used in digital cameras, optical scanners and photosensitive elements of cameras. Its light efficiency can reach 70% (it can capture 70% of incident light), which is better than 2% of traditional film, so CCD was quickly adopted by astronomers.

After the image is imaged on the surface of the capacitor array through the lens, different charges are formed on each capacitor unit according to its brightness. Linear CCD used in fax machine or scanner captures a thin band of light and shadow at a time, while flat CCD used in digital camera or video camera captures a complete image at a time or cuts out a square area from it.

After the exposure is completed, the control circuit will transfer the charge on the capacitor unit to the next adjacent unit. When it reaches the last unit on the edge, the electrical signal will be transmitted to the amplifier and converted into potential.

This cycle is repeated until the whole image is converted into potential, sampled and digitized and stored in the memory. The stored image can be transferred to a printer, a storage device or a display screen. At the same time, in the early 1990s of 1968+0990, the frozen CCD was also widely used in astrophotography and various night vision equipment, and large observatories also continuously developed high-pixel CCD to take pictures of celestial bodies with extremely high resolution.
