摘要:
Image processing techniques are described that reduce the amount of bandwidth required to read an image from memory for display. According to the techniques, a processor stores low change rate display layers in a memory such that a processor can read the display layers from the memory using a reduced amount of processing resources. An overlay module blends low change rate display layers into a combined overlay layer. A processor reads the overlay layer from the memory and selectively processes the overlay layer based on processing information for the overlay layer recorded in memory. The processor then blends the overlay layer and a high change rate video display layer to update a single image for display according to a high change rate. In addition, the overlay module updates the overlay layer based on the low change rate display layers according to a low change rate.
