    Abstract: Methods and apparatus for rendering and displaying high dynamic range (HDR) digital image content. An HDR rendering and display system may support the rendering and display of standard dynamic range (SDR) and HDR content to both HDR-enabled and standard displays. The HDR rendering and display system renders digital image content into the HDR space and maps the rendered HDR content into the display space of HDR or standard displays using display processing techniques that may preserve at least some of the HDR content even for standard displays. The HDR rendering and display system may take into account various information including but not limited to display characteristics such as size, control inputs, current image characteristics such as image brightness, and environmental information such as viewer position and ambient lighting levels to dynamically adapt the rendering and display of the digital image content according to ambient viewing conditions at the target display.

    Abstract translation: 用于渲染和显示高动态范围（HDR）数字图像内容的方法和装置。 HDR渲染和显示系统可以支持标准动态范围（SDR）和HDR内容的渲染和显示，以支持HDR和标准显示。 HDR渲染和显示系统将数字图像内容呈现到HDR空间中，并且使用显示处理技术将所渲染的HDR内容映射到HDR或标准显示器的显示空间中，即使对于标准显示也可以保留HDR内容中的至少一些。 HDR渲染和显示系统可以考虑各种信息，包括但不限于诸如尺寸，控制输入，诸如图像亮度的当前图像特性等显示特性，以及诸如观看者位置和环境照明水平的环境信息，以动态地适应渲染 以及根据目标显示器上的环境观看条件显示数字图像内容。

    Abstract: Lossless image compression using differential transfers may involve an image compression unit receiving image data for an image in a sequence of images and transmitting the image data such that image data for at least some image tiles is transmitted using lossy compression due to resource limitations. The image compression unit may then receive image data for a subsequent image in the sequence and determine that the image data for at least some tiles does not change relative to the image data for corresponding tiles of the previous image. The image compression unit may then transmit image data in a manner sufficient to create lossless versions of tiles for which lossily compressed image data was sent previously.

    Abstract: A computing system that supports the use of multiple displays in display mirroring mode and extended display mode may automatically determine a display mode in which to configure the system (with little or no user input) based on various characteristics of the displays in the system. For example, the system may determine that a television, projector, or other presentation type display is connected in the system, and in response, may determine that the system should be configured in a display mirroring mode, rather than in an extended display mode. The system may also determine that the presentation type display is the preferred display, and may render image content in a best (or preferred) mode for that display using its native resolution, aspect ratio or color profile. The system may then scale the rendered image content for display on other (non-preferred) displays, such as an internal display, without re-rendering it.

    Abstract translation: 支持在显示镜像模式和扩展显示模式下使用多个显示器的计算系统可以基于系统中的显示器的各种特性自动地确定其中配置系统（具有很少或没有用户输入）的显示模式。 例如，系统可以确定在系统中连接电视，投影仪或其他呈现型显示器，并且作为响应，可以确定系统应该以显示镜像模式而不是扩展显示模式来配置。 系统还可以确定呈现类型显示是优选的显示，并且可以使用其原始分辨率，宽高比或颜色配置文件，使该显示的图像内容以最佳（或优选的）模式呈现。 然后，系统可以缩放渲染的图像内容以在其他（非优选的）显示器（诸如内部显示器）上显示，而不重新渲染它。
