The present invention has an object of realizing highly reliable search with high precision by obtaining a clear view image over a wide view. In particular, a reflection mirror is formed so as to correspond to an image pick-up element at a focus surface of a converging lens of an image pick-up camera and the image pick-up camera is arranged to be capable of freely performing scanning by a scanning mechanism portion. As a result, with the image pick-up camera kept performing linear scanning, the reflection mirror performs triangular scanning in a direction opposite to the scanning direction of the image pick-up camera for every frame cycle T and a light wave taken in by the converging lens is introduced to the image pick-up element for every one frame, thereby to obtain a static view image. The desired object is thus achieved.

La présente invention vise à effectuer avec beaucoup de précision une recherche très fiable, en obtenant une image de visée claire à grand angle. En particulier, un miroir réflecteur est conçu pour correspondre à un élément de prise de vues à une surface de mise au point d'une lentille convergente d'une caméra de prise de vues. Cette caméra est adaptée pour effectuer librement le balayage grâce à un mécanisme destiné à cette fin. Comme résultat, pendant que la caméra de prise de vues poursuit un balayage linéaire, le miroir réflecteur procède à un balayage triangulaire en direction opposée à la direction de balayage de la caméra de prise de vues pour chaque cycle d'image T. Une onde lumineuse captée par la lentille convergente est alors transmise à l'élément de prise de vues pour chacune des images, afin d'obtenir une image de visée statique. L'objet visé est ainsi obtenu.
