Abstract: Video data obtained by imaging a target region is acquired, and a partial region video including at least a detection target object is detected from a frame of the acquired video data. Then, feature information indicating a feature of a motion of the object is extracted from a plurality of the partial region videos detected in a first section for each first section including a plurality of frames, and first behavior feature information is generated by structuring the plurality of pieces of extracted feature information in a second section. Subsequently, a cost reflecting similarity between the generated first behavior feature information and each of a plurality of pieces of second behavior feature information related to the object prepared in advance is calculated, the second behavior feature information in which the calculated cost satisfies a preset condition is detected as search behavior information, and the detected search behavior information is output.
