Abstract: A method of and device for providing image frames is provided. The method includes outputting portions of a first frame that have changed relative to the one or more other frames without outputting portions of the first frame that have not changed relative to the one or more other frames. Each of the portions are determined to be changed if a rendering engine has written to a frame buffer for a location within boundaries of the portion. This outputting is done in response to one or more portions of a first frame having changed relative to one or more other frames.

Abstract translation: 提供了一种用于提供图像帧的方法和装置。 该方法包括：输出相对于一个或多个其他帧已经改变的第一帧的部分，而不输出第一帧相对于一个或多个其他帧没有改变的部分。 如果渲染引擎已经写入到用于该部分的边界内的位置的帧缓冲器，则确定每个部分被改变。 响应于相对于一个或多个其他帧已经改变的第一帧的一个或多个部分来完成该输出。
