Title: IMAGE SEARCH SYSTEM, IMAGE SEARCH DEVICE, AND IMAGE SEARCH METHOD
Abstract:
An image search system comprising an imaging unit that captures video, a search unit that contains a processor and a storage unit and searches the aforementioned video for an image, an input unit that accepts information to be inputted to the search unit, and a display unit that displays information outputted by the search unit. The storage unit holds information indicating the shapes of trajectories that represent the motion paths of a plurality of moving objects extracted from the video. When information indicating the shape of a trajectory is inputted from the input unit, the search unit searches the plurality of moving-object trajectories held in the storage unit for a trajectory that is similar to the inputted trajectory shape, and if such a trajectory is found, the search unit makes the display unit display an image of the moving object that moved along the found trajectory.
