ABSTRACT:
In a moving body detection device of a camera in this invention, in order to correctly detect an area in which a target moving body is present even when the camera moves, an area in which the moving body is present is detected from a plurality of divided areas by comparing respective motion vectors. Further, in the moving body detection device of a camera in this invention, an image of an object derived by use of a video camera is detected by a CPU via a Y/C separation circuit, A/D converter circuit and video RAMs. Motion vectors of image portions are detected from the two image portions which are extracted at two different timings from desired first and second preset areas of the detected image displayed on a display unit by means of the CPU, video RAMs, RAM and ROM. Then, whether an object which is present in the first preset area is a moving body or not is determined by the CPU based on the detected motion vector of the image.
