Question

Motion pictures create an optical illusion known as persistence of vision. What should be the minimum frame rate of motion pictures so that we can distinguish between different images?

• A. $16$
• B. $12$
• C. $20$
• D. $24$

Answer 1

The correct option is A $16$

Persistence of vision is also known as an optical illusion that takes place when pictures are in motion. This happens when the human brain perceives more than two images that are formed on the retina within a time period of $1/16th$ of a second.
Frame rate of motion pictures should be less than $16$ to be able to distinguish between different images.
