A high-speed camera is a device capable of capturing moving images with exposures of less than ⁠1/1 000⁠ second or frame rates in excess of 250 frames per second.^[1] It is used for recording fast-moving objects as photographic images onto a storage medium. After recording, the images stored on the medium can be played back in slow motion. Early high-speed cameras used photographic film to record the high-speed events, but have been superseded by entirely electronic devices using an image sensor (e.g. a charge-coupled device (CCD) or a MOS active pixel sensor (APS)), typically recording over 1 000 frames per second onto DRAM, to be played back slowly to study the motion for scientific study of transient phenomena.^[2]
