Terminal, jamming detection method, device as well as game jamming detection method and device

The embodiment of the invention provides a jamming detection method. The jamming detection method comprises: when RGB values, obtained in real time, of a plurality of pixel points on a terminal screen change, recording current time stamps to obtain a time stamp sequence; converting the time stamp sequence into a jamming delay sequence, wherein each jamming delay datum in the jamming delay sequence is a difference value between adjacent two time stamps in the time stamp sequence; and calculating, based on the jamming delay sequence, to obtain jamming information, wherein the jamming information comprises one or more of the following: variance of the jamming delay sequence, quantity of jamming delay data, greater than an average value of the jamming delay sequence by a preset threshold value, in the jamming delay sequence, and a difference value between a minimum value with a delay duty function greater than or equal to 95% and the average value of the jamming delay sequence, wherein the delay duty function is a proportion of data, smaller than or equal to the minimum value, in the jamming delay sequence. The invention further correspondingly provides a jamming detection device, a terminal as well as a game jamming detection method and a device.
