Camera tube camera

1. Now the EFP machine in the TV studio has been digitized.

2. The imaging effect of 2.ccd and cmos camera is better than that of camera tube.

3. The imaging of camera tube is far from the accuracy of film, so it will be replaced by digital camera.

The highest analog TV signal is 480 TV line. At present, the standard definition TV signal has exceeded 520 TV line, and the front end is shot by high-definition digital camera, so the video clarity of this football match has been significantly improved compared with previous football matches.

5. It's not just the storage mode. Now the front-end image acquisition, compression conversion and transmission processes are all digital, so the signal loss is extremely small and the effect of terminal playback is also improved.

6. At present, camera tubes and cameras are basically eliminated. Football matches and Spring Festival parties are all digital high-definition EFP cameras.

7. The price of 7.ccd or cmos camera is not much cheaper than that of camera tube, because it still needs a lot of cutting-edge technology to support it.

8. The most expensive camera should be the studio EFP camera, which is worth more than one million.

9. Photography and cameras are not at the same technical level and cannot be compared horizontally.
