kuvanopeus

Kuvanopeus is the speed at which images are produced by a camera, video system, or display. It is typically expressed in frames per second (fps) or hertz (Hz) and describes how many distinct still images are generated in one second. In photography and cinematography, kuvanopeus determines how motion is portrayed and how exposure timing is managed. Standard cinema uses 24 fps, television commonly 25 or 30 fps, while many modern broadcasts and games use 60 fps or higher. High-speed or slow-motion capture uses much higher kuvanopeus, ranging from a few hundred to several thousand fps, often with very short exposures.

In displays and video processing, kuvanopeus also relates to how many frames a screen can refresh per second (refresh rate). A higher refresh rate reduces motion blur and makes fast motion appear smoother, provided the content is delivered at a matching rate. When capture fps and display refresh rate differ, techniques such as frame interpolation or frame duplication may be used to ensure smooth playback.

Technical considerations include achieving a given kuvanopeus through sufficient lighting and sensor readout speed; higher frame rates require shorter exposure times, which can increase noise or necessitate more light. Higher kuvanopeus yields larger data rates and storage needs, and may constrain color sampling or bit depth. The choice of kuvanopeus depends on the intended use (cinematic feel, documentary realism, or sports replay), lighting conditions, equipment, and delivery format.
