Pyroelectric camera device
专利汇可以提供Pyroelectric camera device专利检索，专利查询，专利分析的服务。并且PURPOSE: To eliminate the need for a complicated storage circuit and its peripheral circuit by utilizing a signal specific to the pyroelectric effect positively.
CONSTITUTION: A signal processing arithmetic circuit 6 obtaining a gravity center coordinate to signals with respect to the entire pattern immediately from picture signals at panning mode reproduced by using a pyroelectric 2-dimension sensor 3 and outputting a universal head control signal reproduced to a predetermined reference position on the pattern to a camera rotary universal head drive section 4 so as to vary the azimuth of a pyroelectric camera 1 and to move the gravity of the reproduced picture to the reference point and a means 10 (chopper automatic drive circuit) triggering the chopper 9 by using the picture signal and driving it automatically or the like, are provided. In using the pyroelectric camera 1 to find out a mobile object in the visual range, the image is picked up by the panning mode, the gravity center on the pattern is detected immediately from the obtained output signal, the camera stand is moved to trace and reproduce the object. In such a case, the chopper 9 is operated automatically and the object to be supervised is reproduced at the center of the screen.
