Question

When watching something electronic, such as a phone or camera on a video, why does the screen flicker rapidly?

In: Technology

Answer 1

Because those images are in fact flickering rapidly.

The flickering happens so fast our eye blends the images together, creating the illusion of motion. But cameras aren’t fooled, they catch the screen in mid flicker and send that image along to us.
