Abstract: An output device is set to a first state in which a value of a first characteristic of the output device is set to a first value. Pixel adjustment values for plural gray levels are set to first pixel adjustment values in response to the output device being set to the first state. The value of the first characteristic is changed from the first value to a second value to set the output device to a second state. The pixel adjustment values for the plural gray levels are updated to second pixel adjustment values in response to the output device being set to the second state. The second pixel adjustment values are derived based on the second value of the first characteristic. Pixel values applied to a plurality of pixels of the output device are corrected based on the second pixel adjustment values.

Abstract: Pixel values of image content are lowered in response to setting a display mode so that the lowered pixel values of the first image content are mapped to a first color gamut. The first color gamut is defined by a nominal range space and is lower than a native color gamut of a display panel. The native color gamut is defined by the nominal range space and an extended range space that is outside of the first color gamut. One or more parameters are obtained for the image content in the display mode. A color boosting operation is performed for, from among the lowered pixel values of the image content in the nominal range space, each of first pixel values that meet one of the parameters. A color associated with each of the first pixel values is proportionally enhanced without changing a corresponding hue to utilize the extended range space.

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: A data processing system can store a long-term history of pixel luminance values in a secure memory and use those values to create burn-in compensation values that are used to mitigate burn-in effect on a display. The long-term history can be updated over time with new, accumulated pixel luminance values.

Abstract: Methods and apparatus for rendering and displaying high dynamic range (HDR) digital image content according to a perceptual model. A model of viewer perceptual range may be determined according to the perceptual model based on inputs including ambient lighting conditions, display panel characteristics (e.g., light leakage and reflected ambient light), and/or display panel settings. The system may determine, according to the model of viewer perceptual range, a brightness level that defines a lower portion and an upper portion of a display space of the display panel, and a maximum rendering value M. Digital image content may be rendered according to the maximum rendering value M to generate HDR content in a dynamic range of (0.0-M). The rendered HDR content may then be mapped into the display space of the display panel according to the brightness level.

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.
