009 Apparent Motion
An illusion of motion created when images are displayed in rapid succession.
• Apparent motion occurs when still images are presented in rapid succession at different positions and orientations, creating the illusion of motion.
• Apparent motion can be created by changing the position or orientation of objects across images, or by moving background elements around a fixed object.
• The rate of image presentation can be as low as 10 images or frames per second. The standard frame rate for television and movies is 24–30 frames per second. Frame rates of 60+ frames per second are indistinguishable from reality.
• Consider apparent motion when creating animations or videos. Maximize frame rates to present the most natural motion possible.
