1. A determination apparatus operable to determine whether a predetermined process for detecting a predetermined object is performed on a plurality of frames of a moving image, the apparatus comprising a processor configured to: determine whether the predetermined object is detected by the predetermined process performed on a first one of the plurality of frames of the moving image; and determine, when it is determined that the predetermined object is detected in the first one of the plurality of frames, that the predetermined process for detecting the predetermined object is performed on a second one of the plurality of frames that is later than the first one of the plurality of frames by a first frame number and that the predetermined process for detecting the predetermined object is not performed between the first and the second one of the plurality of frames, and when it is determined that the predetermined object is not detected in the first one of the plurality of frames, that the predetermined process for detecting the predetermined object is performed on a third one of the plurality of frames that is later than the first one of the plurality of frames by a second frame number smaller than the first frame number.
