Képgyorsaság

Képgyorsaság, often translated as "image speed" or "frame rate" in English, refers to the temporal resolution of a visual system, particularly in the context of displaying moving images. It quantifies how many distinct still images, or frames, are presented to the viewer within a given period of time, typically one second. A higher képgyorsaság means more frames are displayed per second, resulting in smoother and more fluid perceived motion.

In digital displays, such as computer monitors and televisions, képgyorsaság is a crucial parameter that influences the viewing experience. Common frame rates include 60 Hz, 120 Hz, and even higher for specialized applications. For instance, video games often benefit from high képgyorsaság to reduce motion blur and provide a more responsive gameplay experience. Similarly, high-frame-rate video content, like slow-motion replays in sports, utilizes a higher képgyorsaság to capture and display finer details of rapid movements.

The human visual system's perception of motion is also influenced by the képgyorsaság of the stimuli it encounters. While the exact threshold varies among individuals, there is a point at which the brain can no longer distinguish individual frames, and motion appears continuous. This phenomenon is known as flicker fusion. Therefore, understanding képgyorsaság is essential for both the creation and the perception of dynamic visual content.
