摘要： 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.

摘要： 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.-HD in which the trailing edge of the trigger pulse signal is caused to be timing of reference, which are generated in accordance with the trigger pulse signal TRIG-IN by a modulated HD signal preparation section 22 and a shutter control signal SHCLTL in which the leading edge of the trigger pulse signal TRIG-IN is caused to be timing of reference to allow it to carry out image pick-up operation of object for effective exposure time period corresponding to pulse width of trigger pulse signal TRIG-IN generated by the pulse width adjustable setting circuit 5, thereby making it possible to synchronize the image pick-up operation with a synchronizing signal of random period. In addition, continuous adjustable control of the exposure time period over broad range can be carried out.

摘要： 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.
