Why is the actual number of pixels shot by the camera inconsistent with the effective number of pixels? Even higher than the effective pixel?

The machines you mentioned are both commercial and civilian.

1, moving image pixel

This parameter is determined by the recording part, and the dynamic image is realized by the recording format, such as interpolation algorithm. For example, the resolution after photoelectric conversion is 1440, and the direct operation can reach 1920.

2. Effective pixels

Effective pixels are determined by CCD(CMOS), so they actually exist.

In this way, there will be a situation that the effective pixel is lower than the dynamic image pixel.

Broadcast cameras do not have this problem, and the effective pixels are generally higher than moving images.

This is determined by different uses.
