What do you mean by camera eyes?

This problem appears in camera classification. It's not a prank or a sharp turn, is it?

1\ If it is the eyes of a camera, do you mean the works from the 1920s and 1930s?

2\ Is it a documentary editing method in montage? It is a strong sense of substitution, similar to the lens language that cs is playing now.

3\ When recording, use the "first angle" lens. For example, the protagonist looks at the table, and the next shot is followed by a close-up of the items on the table. The angle is taken from the protagonist's point of view. This is the so-called "first perspective". ....

The questions are too general, and all I can think of are those related to technology.

Unless it is said in Degang Guo's cross talk, you have a pair of eyes like a digital camera, but you often forget to open the lid.
