Development of the brightness quality improving system with the video region detection algorithm

This paper proposes an algorithm for detecting the video region and improving the video quality on a digital monitor. The proposed algorithm is implemented in the circuit board we developed. The algorithm finds the video region by checking where pixels change on a digital monitor. After detecting the video region, a brightness of the video is improved by using the gamma curve. From the experimental results, the proposed algorithm detects the video region well for any video size and improves the brightness of the video.
