PURPOSE:To prevent an object from being annoyed with a high temperature and glare, by emitting a light source irradiating the object at the leading of an odd and an even number field of a video signal. CONSTITUTION:A write pulse Pw is applied to a memory 4 from a control circuit 9 and a video signal Sv is written successively according to an address signal SAD. When a shutter connecting switch 16 is turned on, a connecting point SO goes from ''1'' to ''0'', a signal obtained from an output terminal Q' of an FF12 changes from ''0'' to ''1'' at the leading of an even number field of the video signal Sv, a strobo 81 is emitted to irradiate the object OB. Further, a signal obtained from an output terminal Q' of an FF15 changes from ''0'' to ''1'' with the leading of an odd number field of the signal Sv, a strobo 82 is emitted to irradiate the object OB. Further, the odd and even number fields of the signal Sv are stored in the memory 4, and a still picture is read out from a CRT7. |
