Abstract: Estimating means estimates first characteristic information pertaining to persons present within an area for which an estimation is made, based on first information obtained by tallying signals transmitted from terminal devices of users in the area for which the estimation is made and second information which is statistical information of the area for which the estimation is made. Based on the second characteristic information generated by an analyzing apparatus that analyzes an image, verifying means verifies the first characteristic information estimated by the estimating means. Based on the verification result of the verifying means, correcting means corrects the estimation of the first characteristic information estimated by the estimating means.

Abstract: An image reception unit receives an image from a vehicle through a network. An event prediction unit predicts an event based on the image received by the image reception unit. Based on an event result predicted by the event prediction unit an important area identification unit identifies an area related to the predicted event as an important area in the image. An image adjustment unit adjusts image quality concerning the important area, which is identified by the important area identification unit, in the image.

Abstract: Signal information acquisition means acquires signal information about a traffic light installed on a road. Video acquisition means acquires a video photographed near a first parking lot entrance facing the road. Prediction means predicts whether or not a queue of waiting vehicles will be formed near the first parking lot entrance based on the video near the first parking lot entrance and the signal information. Selection means selects, from among a plurality of the parking lot entrances including the first parking lot entrance, a parking lot entrance to which a vehicle is to be guided based on a result of the prediction performed by the prediction means. Notification means notifies the vehicle of the parking lot entrance selected by the selection means.
