At what rate can the human eye differentiate individual picture frames?

The ability of the human eye to differentiate individual picture frames is generally understood to be in the range of approximately 10 to 12 frames per second. This range highlights the threshold at which a viewer can perceive motion as a series of distinct frames rather than a continuous, fluid movement. Below this frame rate, images may appear choppy or flicker, making it difficult to perceive smooth motion.

Frame rates above this threshold, such as those listed in other choices, are often associated with more fluid motion, allowing the eye to perceive motion more smoothly rather than as discrete frames. However, the point at which frames can be differentiated distinctly lies within the 10 to 12 frames per second parameter, making this answer the most accurate representation of the human eye's perception threshold.
