Abstract:
1. An apparatus for detecting the position of a target image, comprising: a first detecting device for detecting a first position at which a target image is present from a first subject image among a plurality of frames of subject images obtained by sensing, simultaneously or successively, the images of subjects regarded as being substantially identical; a second detecting device for detecting a second position at which the target image is present from a second subject image among the plurality of frames of subject images; and a deciding device for deciding a position at which the target image is present in at least one of the first and second subject images based upon both of the first position detected by said first position detecting device and the second position detected by said second position detecting device, wherein if the amount of fluctuation between the first position detected by said first detecting device and the second position detected by said second detecting device is equal to or greater than a prescribed threshold value, then said deciding device decides that the target image is not present in at least one of the first and second subject images.
