In addition, the invention provides a congestion estimating apparatus capable of easily and accurately estimating the degree of congestion of persons using an image. A situation determining apparatus for analyzing captured moving images or a plurality of captured still images to determine a movement situation and/or a degree of congestion of persons includes: a local image change ratio calculating unit that calculates a time change ratio of a brightness value in a local area of the captured images; and a situation determining unit that analyzes a histogram of the time change ratios of a plurality of local areas calculated by the local image change ratio calculating unit and determines the movement situation of the persons and/or the degree of congestion of the persons."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Situation determining apparatus, situation determining method, situation determining program, abnormality determining apparatus, abnormality determining method, abnormality determining program, and congestion estimating apparatus","description":"The invention provides a situation and abnormality determining apparatus, method, and program capable of easily determining the situation of a monitoring place and the degree of congestion.
