ABSTRACT:
To image a detection object 302 transferred on a transfer path 301 by an imaging device 310, a trigger signal TRIG is obtained by detecting the detection object 302 by an object sensor 303, and operation of the imaging device 310 is controlled by an imaging control device 320 in response to the trigger signal TRIG. The imaging control device 320 includes a pulse width variable setting section 327 for generating a modulated trigger signal MTRIG which enables variable setting of the pulse width on the basis of the trigger signal TRIG, a synchronizing signal generator 323 for generating a standard vertical synchronizing signal VD and a standard horizontal synchronizing signal HD in conformity to the standard television system, a sub-synchronizing signal generator 324 for generating a sub-vertical synchronizing signal EXT-VD which provides a second timing based on a first timing as the timing of the leading edge of the modulated trigger signal MTRIG, and a high-speed horizontal synchronizing signal generator 325 for generating a high-speed horizontal synchronizing signal Hi-HD having a higher frequency than the standard horizontal synchronizing signal HD over a first period.
