Question

Explain the process which enables us to perceive motion in a cartoon film.

Answer 1

Motion in a cartoon film:

1. We notice the display of static pictures on the screen in a specific order in a cartoon film.
2. Our eyes can retain an image for $\frac{1}{{16}^{th}}$ of a second in our retina.
3. When the images on the screen are varied faster than $\frac{1}{{16}^{th}}$ of a second, we tend to perceive a motion.
4. In most cases, static images are made to move across the eye in a series at a rate of $24$ pictures per second, which is quicker than $16$ pictures per second, providing the impression of a moving image.
