Abstract: A moving object 2 transferred by a transfer path 1 is detected by a position sensor 3 to generate a trigger pulse signal TRIG-IN of which pulse width can be adjustably set by a pulse width adjustable setting circuit 5 on the basis of a detection output of the position sensor 3 to deliver, to a CCD camera 10, modulated synchronizing signals T.G.-VD, T.G.

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.

Abstract: Solid-state imaging apparatus for producing an image signal has an active pixel region comprised of a plurality of active light receiving pixels for converting incident light to an image signal, and an optical black region disposed at the peripheral portion of the active pixel region and comprised of a plurality of pixels having a surface provided with a light shield. At least one pixel in the optical black region is located at a predetermined position and produces a position reference signal of a level which differs from that produced by the remaining pixels in the optical black region.
