Abstract
Description
The present invention relates to a high-resolution image processing technique, and more particularly, to a high-resolution image processing camera, a service server, a system, and a method for comparing pixels between arbitrary frames and transmitting and receiving only a pixel whose change over a reference value is detected.
Surveillance cameras are installed in various locations for information gathering and security maintenance. Thus, surveillance cameras are used for various purposes such as information collection, security surveillance, traffic management, and industrial use.
Such a surveillance camera is expanding its utilization area by linking the function of its own image capturing with a mobile terminal. For example, a video captured by a surveillance camera installed in an area to be monitored can be transmitted to a mobile terminal through a mobile communication network, so that the surveillance area can be monitored regardless of time and place. A video surveillance system and method of a surveillance camera over a communication network have been proposed.
On the other hand, as the surveillance performance of the surveillance camera improves, it becomes possible to take a high resolution image, and it is possible to monitor, secure and track more precisely through such high resolution image. However, in order to process such a high-resolution image, a disadvantage arises in that a high-speed processing processor is required or a large-capacity storage is required. In addition, when a high-resolution image is transmitted through a mobile communication network or a network, the efficiency of network operation is deteriorated.
As described above, since a high-resolution surveillance camera has a much larger amount of image information acquired in comparison with a general surveillance camera, there are many disadvantages in the display / storage / transmission / processing of a high-resolution surveillance camera image. For example, when storing and transmitting a high-resolution surveillance camera image, the same compression rate as that of a general surveillance camera image is applied to store and transmit the image information, a much larger storage space or a high-speed communication line is required However, if the compression rate of the image information is increased, the contents of the high-resolution image may be damaged. In addition, when a high-resolution image captured at a high resolution is to be confirmed using a mobile terminal, real-time confirmation is substantially impossible, and even a high-capacity image can not be transmitted.
However, since the high-speed communication service such as LTE-A is realized, it is possible to transmit a large amount of video information. Accordingly, an efficient processing method for high-resolution video information is discussed.
