Abstract
A method for video quality detection and an image processing circuit thereof are provided. In the method, an image-processing circuit receives video signals with at least one frame image, and obtains brightness information of pixels from the frame image. A threshold is applied to the pixels of each frame in order to screen the brightness features that can be regarded as an attribute of each frame image. Therefore, a brightness distribution feature with respect to the pixels of each frame image can be obtained by a statistic method. Statistics showing the brightness distribution can be used to determine a quality of each frame image or a video. The image processing circuit can accordingly select an image processing process corresponding to the image quality of each frame image or the whole video.
