Abstract: A method and user interface for direct setting of black and white points. Black point is set using a slider and matching of gray shades. White point setting is performed by having a setting object move within a defined region, such as a square or circle, with the area where the setting object moves being adjusted dynamically based on the location of the setting object with respect to the defined region. When the area is the desired white, the setting is complete. Preferably the defined region has a varying color border to allow a reference for the user in moving the setting object. A more detailed setting of gray levels can be accomplished by providing a gray scale with reference points. Each reference point has an associated white point setting area, so that settings are developed for each reference point. Settings at other locations are determined by interpolation or extrapolation.

Abstract: Systems, methods, and computer readable media to promote a graphics context when rendering a digital image content with dynamic ranges and/or color gamut outside the current graphics context. Various embodiments render digital image content based on a graphics context that corresponds to an initial image rendering format. During the rendering process a determination is made that indicates the quality of the digital image content exceeds the graphics context's initial capabilities. The various embodiments can select an updated image rendering format based on the quality of the digital image and expand the grahic context's capabilties to correspond with the updated image rendering format.

Abstract: Systems, methods, and computer readable media to improve the operation of a display system are disclosed. Techniques disclosed herein selectively darken a region of an image so that when text or other information is rendered into that region, the contrast between the text or other information and the underlying image in that area is sufficient to ensure the text or other information is visible and readable. In one embodiment, a region into which information is to be rendered may be combined or blended with tone mapped values of those same pixels in accordance with a given function, where the function gives more weight to the tone mapped pixel values the closer those pixels are to the midline of the region and more weight to untone-mapped image pixel values the further those pixels are from the midline of the region.

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: A display may store extended display identification data for communicating the capabilities of the display to a source device such as a graphics processing unit. The extended display identification data may include a red primary color value, a green primary color value, and a blue primary color value. The primary color values in the extended display identification data may be determined during manufacturing. For example, a light sensor may measure the native primary colors of the display, and calibration computing equipment may determine if the native primary colors of the display are within a target color gamut. If the native primary colors of the display are outside of the target color gamut by an amount larger than a threshold, the primary color values in the extended display identification data may be adjusted to account for the color variation.

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: Systems, methods, and devices for dynamically mapping and remapping memory when a portion of memory is activated or deactivated are provided. In accordance with an embodiment, an electronic device may include several memory banks, one or more processors, and a memory controller. The memory banks may store data in hardware memory locations and may be independently deactivated. The processors may request the data using physical memory addresses, and the memory controller may translate the physical addresses to hardware memory locations. The memory controller may use a first memory mapping function when a first number of memory banks is active and a second memory mapping function when a second number is active. When one of the memory banks is to be deactivated, the memory controller may copy data from only the memory bank that is to be deactivated to the active remainder of memory banks.

Abstract: The disclosed embodiments provide a system that drives a display from a computer system. During operation, the system detects an idle state in a first graphics-processing unit (GPU) used to drive the display. During the idle state, the system switches from using the first GPU to using a second GPU to drive the display and places the first GPU into a low-power state, wherein the low-power state reduces a power consumption of the computer system.
