Patent ID: 8284992

Claim:
A monitoring system comprising: an image capturing section that captures a moving image of a monitored area; a variation reduced image generating section that generates a variation reduced image by reducing a temporal variation in an image, based on a plurality of moving-image making-up images included in the moving image captured by the image capturing section; a satisfaction judging section that judges whether the variation reduced image generated by the variation reduced image generating section satisfies a predetermined condition; an output moving image generating section that, when the satisfaction judging section judges negatively, generates an output moving image which has a lower image quality than when the satisfaction judging section judges positively, based on the moving image captured by the image capturing section; and an output section that outputs the output moving image generated by the output moving image generating section, wherein when the satisfaction judging section judges negatively, the output moving image generating section generates an output moving image including the variation reduced image generated by the variation reduced image generating section, and when the satisfaction judging section judges positively, the output moving image generating section uses the moving image captured by the image capturing section as an output moving image.
