1. An image processing apparatus comprising:
at least one memory configured to store one or more instructions; and
at least one processor configured to execute the one or more instructions to:
acquire a first query moving image having a plurality of time-series first frame images and at least one second query moving image having a plurality of time-series second frame images;
compute a feature value of a keypoint detected from an object being included in each of the first frame images and the second frame images;
determine the second frame image associated with each of a plurality of the first frame images; and
perform, for a plurality of combinations of the first frame image and the second frame image associated with each other, processing of integrating the feature values computed from each of the first frame image and the second frame image, and thereby generate an integrated query in which the integrated feature values are arranged in time series.
