Abstract: Techniques are described for determining a region to be updated in a frame based on positional changes of one layer from frame-to-frame. The positional changes may be displacement of a layer or removal of a layer from one frame to the next. In addition to the information of the positional changes, the techniques also utilize all areas for which the image content changed, but the position did not, for determining the region to be updated.

Abstract translation: 描述了基于一帧从帧到帧的位置变化来确定帧中要更新的区域的技术。 位置变化可以是层的位移或从一个框架到下一个框架的移除。 除了位置变化的信息之外，这些技术还利用图像内容改变的所有区域，但是位置没有用于确定要更新的区域。

Abstract: Techniques are described for generating image content for display. A host processor may read opacity information generated by processing circuitry for one or more blocks of pixels of a first layer of a plurality of layers. The host processor may determine an inner rectangular portion of the first layer that is substantially opaque based on the read opacity information, and instruct a display processor to not retrieve, for use in composing the plurality layer, an area of a second layer of the plurality of layers that is occluded by the inner rectangular portion of the first layer. The display processor may compose the plurality of layers to generate an image frame for display.
