There is provided a system and method for providing an application service using image data. One image data processing server collects images (for example, still images and moving images) captured by various kinds of image capturing apparatuses, such as CCTV systems and processes the collected images into data required to provide application services. A plurality of application service servers only provide processed data of the image data processing server without requiring an additional process to a display device of a user. Accordingly, the configuration of each of the application service servers is simplified to thereby reduce manufacturing costs.
