DISPLAY HARDWARE ENHANCEMENT FOR INLINE OVERLAY CACHING

Abstract:

Methods, systems, and devices for image processing are described. A device may determine one or more static layers of a layer stack and one or more updating layers of the layer stack. The device may determine an order of the one or more static layers, or the one or more updating layers, or both in the layer stack. In some examples, the device may modify the order in the layer stack by positioning the one or more static layers below the one or more updating layers in the layer stack. Each static layer of the one or more static layers may be associated with a first blending equation and each updating layer of the one or more updating layers may be associated with a second blending equation. As a result, the device may process the layer stack based on the modified order.
