Method for compositing multi image layers

The multi-layer composite image method is provided. The multi-image-layer composite method wherein each by dividing the storage area of ​​the frame buffer into a plurality of tile regions, and determining each image to perform the composite with respect to the tile region layer, and performing composite with respect to the tile region of the respective the ability to create composite image layers for each tile region, and to merge the composite image layers for each tile region of each, including, but to complete the overall composite image layer, generating the composite image of the layer, top (top) image If judging from the layer bottom (bottom) lid need for image layers lower image layer order and read the information of the image layers by using the information of the image layer of, and the lead needs the lower image layer, the image layer the Effective least significant (effective bottom) relative to the defining, and the effective least significant image layer to the image layers, but to perform a composite of the effective least significant image layer and the top image layer, performing a non-aqueous is a composite of sub-image layer, the composite image layer It includes generating.
