Abstract
A method and system for drawing and rendering a graphic in real-time in a layered manner are provided. Adjacent application frames spaced with a time period are extracted, a scene change rate is calculated, and whether the scene change rate exceeds a preset change rate threshold is determined. If the scene change rate does not exceed the preset change rate threshold, graphic elements are grouped to a same graphic layer. If the scene change rate exceeds the preset change rate threshold, M application frames chronologically located between the adjacent application frames are extracted. Each application frame is divided into N regions, and a scene change rate of adjacent application frames is calculated for each region. An average scene change rate for each region is calculated, a layering operation is performed based on the average scene change rate, and graphic layers are drew and rendered separately.
