ない。[0005] However, particularly when the target object exists in the field, there is a high possibility that many similar objects (object candidates) exist. For this reason, performing image processing for each object candidate increases the amount of processing, and as a result, delays the determination processing. Also, when the type of image processing is simply increased, the processing amount increases, and the processing is similarly delayed. Further, the processing accuracy is not always improved.

High in nature. As a result of this,
In the continuous determination process, there is a high possibility that the process may be stopped or a situation in which a sufficient feature amount cannot be extracted for the target candidate.
