1. A moving information analyzing system comprising: a camera; and a server that is connected to the camera, wherein the camera includes: an imaging section that, in operation, captures an image of a predetermined imaging region; a background image generating section that, in operation, repeatedly generates a background image of a captured image of the imaging region at predetermined timings by removing a moving object from the captured image; a moving information analyzing section that, in operation, extracts moving information, the moving information visually indicating a location at which a moving object stays or a location through which the moving object passes in the imaging region included in the captured image; and a transmitter that, in operation, transmits the background image generated by the background image generating section and the moving information extracted by the moving information analyzing section to the server at a predetermined transmission cycle, and wherein the server includes; an image generating section that, in operation, generates a moving information analysis image in which the moving information is superimposed on the background image of the captured image, the moving information analysis image including a heat map; and a display control section that, in operation, displays the moving information analysis image generated by the image generating section on a display unit.
