Imaging systems can often gather higher quality information about a field of view than the unaided human eye. For example, telescopes may magnify very distant objects, microscopes may magnify very small objects, and high frame-rate cameras may capture fast motion. The present disclosure includes devices and methods that provide real-time vision enhancement without the delay of replaying from storage media. The disclosed devices and methods may include a live view display and image and other information enhancements, which utilize in-line computation and constant control. The disclosure includes techniques for enabling push-button slow motion effects through buffer management and the adjustment of a display frame rate.
