The method enhances the perceived refresh frequency of a displayed picture on a projector display screen. It achieves this by producing synthetic frames between the precise frames acquired from the video supply. For example, a projector receiving a 60Hz sign may make use of this course of to simulate a 120Hz or increased refresh fee on the display screen. That is finished by analyzing the movement between successive frames and creating middleman frames which can be then inserted into the video stream.
This system can scale back movement blur and judder, resulting in a smoother and extra visually interesting viewing expertise, significantly noticeable in fast-paced motion scenes or when projecting video video games. Traditionally, these options have been present in high-end televisions and have steadily turn out to be extra widespread in projector know-how to enhance picture high quality and compete with the visible readability of different show varieties. Early strategies have been computationally intensive, however developments in processing energy have made them extra environment friendly and sensible for real-time functions.
