How many megapixels is the camera used in TV station?

Theoretically, 420,000 pixels are enough for the sensor of standard definition machine, and 265,438+10,000 pixels are enough for the sensor of high definition machine.

The actual equipment is basically the same. The standard definition machine has about 450,000-600,000 pixels, and the high definition machine has about 2.2 million pixels.

Generally, broadcast cameras are three 1/3-inch or 2/3-inch sensors, 3CCD or 3CMOS, and each sensor is only responsible for imaging one of the three colors of red, green and blue, which saves the process of splitting light with a filter before the sensor and re-interpolating to calculate the color, so the picture quality is naturally better.

Broadcast-grade machines also have a single sensor model, but the sensor area is larger. For example, Sony's F35 digital movie camera uses a 35mm Quan Huafu high-sensitivity CCD sensor, but the pixel is not too high, it is12 million. But this is the top sensor of the camera, because the grating filter in front of the sensor is not an ordinary filter that needs interpolation calculation in the later stage, and it can achieve the technical lossless RGB4:4:4. The sensor of Sony's latest F65 movie camera is a 20-megapixel CMOS sensor, which is relatively high.

Whether it's household equipment, professional equipment or broadcasting equipment, the number of pixels of digital imaging components has never been the key factor to determine the grade effect of equipment. It is wrong to think that the higher the pixel, the better the effect and the higher the device. There are many factors that affect the effect of equipment.
