Abstract:
1. A high speed photographic device which photographs a photographic subject which periodically repeats invisible high speed motion, and displays in real time a photography image which is in synchronization with a motion cycle of the photographic subject, the high speed photographic device comprising: a synchronous cycle adjustment unit which is for designating a synchronous cycle that is M times (M is an integer of not less than 1) as long as the motion cycle; an imaging unit which is made up of a solid state imaging device composed of a plurality of pixels, and repeatedly photographs the photographic subject at a photography cycle that is 1/N (N is an integer of not less than 1) as long as the synchronous cycle; and a display unit which displays in real time the photographic subject by displaying the photography image of every synchronous cycle photographed by the imaging unit, every display cycle of not less than a visual minimum cycle in which switching of display is visible, wherein the synchronous cycle adjustment unit is made up of a unit which adjusts the synchronous cycle at not less than a time which reads one pixel of the solid state imaging device and a step width smaller than the visual minimum cycle, within an adjustment range which does not include less than the visual minimum cycle, and wherein when the synchronous cycle is changed by the synchronous cycle adjustment unit, the imaging unit continuously photographs the photographic subject at a photography cycle corresponding to a changed synchronous cycle, and the display unit continuously displays the photography image of every changed synchronous cycle.
