Information regarding a room, such as the shape of the room, is inferred simply and precisely. A room information inferring apparatus for inferring information regarding a room includes: an imaging unit that captures an image of a room that is to be subjected to inferring; a person detection unit that detects a person in an image captured by the imaging unit, and acquires the position of the person in the room; a presence map generation unit that generates a presence map indicating the distribution of detection points corresponding to persons detected in images captured at different times; and an inferring unit that infers information regarding the room based on the presence map. The person detection unit can detect the face, head, or upper body of the person in the image, and acquire the position of the person in the room based on the position and size of the face, head, or upper body in the image. The inferring unit can infer that a polygon circumscribed around the distribution of detection points in the presence map is the shape of the room.
