METHOD AND DEVICE FOR PROVIDING A COMPOSITION OF MULTI IMAGE LAYERS
Abstract:
A method for multi image layer composition includes dividing a frame buffer into tile areas, for each the area, determining image layers to be composited, for each tile area, generating a composite image layer by compositing its determined image layers, and merging the composite image layers into an overall composite image layer, wherein generating the composite image layers for at least one of the tiles comprises reading image layer information of the image layers from a top image layer to a bottom image layer, determining whether to read a lower image layer using the information of the image layers thereabove, if the lower image layer is determined not to be read, defining the image layer above the lower image layer as an effective bottom image layer, and compositing the effective bottom image layer with upper image layers, and not compositing the effective bottom image layer with an image layer thereunder.
