Abstract
The present invention provides a layer composition optimization method and apparatus. The method comprises the following steps that a layer identification unit adds identification information to unchanged layers; and then a layer identification determination unit determines whether a to-be-composited layer has the identification information, if so, a layer data acquisition unit does not acquire layer data from a layer buffer area corresponding to the layer, if not, the layer data acquisition unit acquires the layer data from the layer buffer area corresponding to the layer, and a layer composition unit composites all the layer data required to be composited to a display buffer area and stores the composited layer data in the display buffer area. Due to the fact that the identification information is added to the unchanged layers, when the layers are composited, if the to-be-composited layer has the identification information, the data in the frame buffer area corresponding to the layer are not carried, namely the layer is not involved in compositing the next frame image, so that the occupancy rate of system resources during a layer composition process is saved, and power consumption is reduced.
