In addition, the existing video monitoring system is limited to a maximum of 16 channels for real-time display due to various restrictions such as real-time display constraints or bandwidth constraints. For example, even if an existing video monitoring system can simultaneously record 64 video images from 64 channels, the number of channels that can be displayed in real time can be less than 64 channels. That is, the conventional video monitoring system can not display all the images of the connected camera simultaneously in real time because of various restrictions.

An embodiment of the present invention is directed to an image processing apparatus and a method for processing an image of an object, And a photographing apparatus.

Accordingly, even when the number of channels that can be displayed in real time is limited due to various constraints, the present invention can display real-time or near-real-time images captured by the image capturing apparatuses more than the limited number of channels.

The receiving unit 220 receives data related to an image photographed from at least one image capturing apparatus connected to the first sub-management image capturing apparatus 200 via a network.

More specifically, the receiving unit 220 may receive data related to an image from one or more image capturing apparatuses set to transmit image data captured by the first sub-management-type image capturing apparatus 200. One or more image capturing apparatuses set to transmit image data photographed by the first sub-management-type image capturing apparatus 200 are referred to as a first group.

Referring to FIG. 1, for example, the receiving unit 220 receives data related to a first image from a first image capturing apparatus, a second image capturing apparatus, and a third image capturing apparatus included in the first group, Data and data relating to the third image.

The data relating to the first image is data relating to the image photographed by the first image capturing apparatus. The data relating to the second image is data relating to the image photographed by the second image photographing apparatus. The data relating to the third image is data relating to the image photographed by the third image capturing apparatus.

For example, the receiving unit 220 can receive data related to the image photographed by the image photographing apparatus included in the first group by a real time streaming protocol (RTSP) method. Alternatively, the receiving unit 220 may receive data related to the image photographed by the image photographing apparatus included in the first group using an ONVIF (Open Network Video Interface Forum) protocol.
