Design and implementation of surveillance embedded IP camera with improved image quality using gamma correction for surveillance camera

摘要

The need for a security improvement of an area generally associated with the assets which are located in that area. The protection mechanism of these assets creates the need for a device which can be used as a monitoring tool. A surveillance camera is a popular device for monitoring an area. For the purposes of data integration, the camera surveillance based on IP (Internet Protocol) is widely used. However, the maintenance of a file server and the provision of the data storage require substantial funding and effort. In addition, if the surveillance activity is carried out in the indoor room, sometimes the lack of lighting in the room can make data retrieval becomes not clearly visible. Thus it creates the need for restoring the data by improving its image quality. This study is going to design a device such as IP surveillance camera which based on an embedded system, with improved image recording feature by using gamma correction and data storage feature which integrates with cloud service through a network based on IP (Internet Protocol). In the image correction mechanism, the measurement of image quality improvement is executed by using a histogram. The measurement of image quality improvement based on the human perspective is also provided.
