Abstract: An image monitoring system is provided with: a region forecast acquiring unit (101) for acquiring a region forecast which is predictive information about a predetermined item designated as a factor causing a change in a capture environment that is the environment of a capture region, wherein the predictive information serves as predictive information about the predetermined item at a future time in a predetermined region including the capture region where an image to be image-analyzed is captured; a change index specifying unit (102) for specifying, based on the acquired region forecast, a change index including at least a change timeslot that is a timeslot during which the change in the capture environment is brought about; and a detection sensitivity setting unit (103) for altering, based on the specified change index, a setup parameter that is a parameter for detecting an abnormality in the image analysis.
