When was the color camera invented?
1949, the United States first developed the world's first three-gun three-beam color picture tube;
1957, an all-glass color display tube was developed.
1964, a rectangular picture tube with full glass shell was developed;
1969 A kinescope with black background was developed, and the brightness was doubled.
1968, Sony Corporation of Japan developed a three-color display tube with one gun;
1972, the United States successfully developed a color display tube with automatic convergence error correction.
The use of color camera is very simple, usually as long as the lens is installed correctly, the signal line is connected and the power supply is connected. However, in actual use, if the lens cannot be installed correctly and the state of the color camera and lens cannot be adjusted, the expected use effect may not be achieved.
Extended data
If you use a color camera in the situation where the illumination changes greatly, it is best to connect the automatic aperture lens and turn off the electronic shutter switch of the camera.
If you choose manual aperture, you should turn on the electronic shutter switch of the camera. When the application site is brightest (the ambient light illumination is maximum), the aperture of the lens should be as large as possible, and the imaging is still the best (the image should not be too white and overloaded). Adjust the lens. Just install the protective cover and bracket.
