FIELD: physics, video.
SUBSTANCE: invention relates to video processing techniques and specifically to automation of the process of classifying video content by genre and real-time content. The result is achieved by calculating brightness and saturation of each frame pixel described by values in red, green and blue colour channels; calculating the absolute value of brightness gradient for each frame pixel; performing colour classification of each frame pixel; calculating statistics based on results of colour classification for the whole frame; calculating statistics based on results of colour classification for green frame regions; determining if said frame is a game incident in field sports based exclusively on characteristics of the current frame; determining if the current frame belongs to the same scene as the previous frame; using the detection result obtained for the previous frame as a refined detection result if the current frame belongs to the same scene as the previous frame of the video sequence; or using the detection result obtained for the current frame based exclusively on characteristics of the current frame as the refined detection result if the current frame does not belong to the same scene as the previous frame of the video sequence.
EFFECT: automatic adjustment of image settings.
