HIGH-SPEED FRAME-BY-FRAME RECORDING TELEVISION CAMERA SYSTEM

摘要

PPROBLEM TO BE SOLVED: To provide a high-speed frame-by-frame recording television camera system in which three or more instantaneous still pictures each indicating a motion of an object moving at very high speed or a state of a natural phenomenon changing at very high speed moment by moment can be extracted continuously at extremely short time intervals of several s to ten and several s. PSOLUTION: The high-speed frame-by-frame recording television camera system is provided with: an optical branching system for branching an optical image of the object incident from a lens into a plurality of directions; a plurality of solid-state imaging devices for converting the plurality of branched optical images into electric signals; an electronic shutter control means for enabling the plurality of solid-state imaging devices to perform exposure twice at the exposure intervals of several s to ten and several s; a plurality of one-frame memories for individually recording two instantaneous still pictures outputted from each of the plurality of solid-state imaging devices; and a memory output switching device for repeatedly read the instantaneous still picture recorded in the one-frame memory the plurality number of times to form a still picture of an observable time length, and switching the still pictures in the order of imaging and outputting as frame-by-frame recording motion picture.
