Abstract: An image processing device according to an embodiment includes: a depth estimation unit that, when a size of a differential region between a first frame and a second frame at a timing later than a timing of the first frame in chronological order in a moving image satisfies a predetermined condition and is large, estimates a depth of at least a region corresponding to the differential region in the second frame; and a depth estimation result update unit that updates an estimation result of the depth of the first frame by using the region corresponding to the differential region to output the updated estimation result as a new estimation result of the depth of the second frame.

Abstract: Activity information acquirer that acquires activity information representing an activity level of a moving object for each of a plurality of predetermined detection elements acquired through division performed on a captured image, a target area setter that sets a target area on a facility map image acquired by drawing a layout on the inside of the facility, an indexed information generator that generates indexed information acquired by indexing the activity state of the moving object in the target area on the basis of the activity information, an activity state display image generator that generates a digest image representing an overall activity state of the moving object in the target area on the basis of the indexed information, and an output information generator that generates output information which includes display information acquired by superimposing an activity state display image on the facility map image.
