AbstractIn a moving body tracking apparatus having a moving body recognition circuit and TV camera, the moving body recognition circuit includes: a contour signal generator for producing a first contour signal indicative of contour of an image defined by at least one field, a second contour signal subsequent to the first contour signal, and a third contour signal subsequent to the second contour signal, a first and a second memory for temporarily storing, respectively the first and the second contour signals; contour line width increasing circuit responsive to the first and second memory for increasing the width of contour line represented by output signals of the first and second memory; and comparator responsive to the third contour signal and output signal from the contour line width increasing circuit for producing an output signal when a contour line represented by the third contour signal is out of phase with a contour line represented by the output signal from the contour line width increasing circuit. As a result, moving body except for undesired small movement can be satisfactorily extracted.
