Abstract: A display device is used in conjunction with: (1) optical sensors to collect information about ambient conditions in the environment of a viewer of the display device; and/or (2) privacy element identification and detection mechanisms (PEDMs) to collect information about the presence, orientation, and/or type of privacy elements being used in conjunction with the display device. For one embodiment, a processor in communication with the display device may create a view model based, at least in part, on the predicted effects of the ambient environmental conditions and/or presence of privacy elements being used in conjunction with the display device on the user's viewing experience. The view model may be a function of gamma, black point, white point, privacy element orientation and/or type, backlighting, field of view, number of viewers, color offset, or a combination thereof. The view model is also referred to as an ambient/privacy model.

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: The present disclosure describes techniques for removing unnecessary processing stages from a graphics processing pipeline based on the format of data passed between the stages. Starting with a stage at a middle point in a pipeline, formats of data that are input to and output from the middle stage may be compared to each other. If the formats match, the middle stage may be removed from the pipeline. Thereafter, the format of data input to a pair of middle stages of the pipeline and output from the pipeline may be compared and, if they match, the middle pair may be deleted. This process may repeat until a middle pair is found where no match occurs between the input and output format. The remaining stages of the pipeline may be retained. In cases where a pipeline is not symmetrical, the formats of data at each node may be compared to each other. If a node possesses a format that does not match the format of any other node, then the stages between the node and its closest endpoint in the pipeline may be retained.

Abstract: Managing the display of an electronic device includes receiving an instruction to activate an enhanced state of the display and obtaining a current operating value of the display operating in a base state. An enhanced operating value is determined for the display based on the current operating value and a power budget allocated to the display. The enhanced operating value may be greater than the current operating value and is less than a maximum operating value of the display in the enhanced state. The display is instructed to operate in the enhanced state at the enhanced operating value.

Abstract: A device comprises memory, a display characterized by a characteristic, and processors coupled to the memory. The processors receive data indicative of a preferred adaptation technique and intended display parameter. The processors adapt the content item to a display color space and the intended display parameter based on the preferred adaptation technique. The processors modify the intended display parameter based at least in part on the display characteristic to obtain a modified display parameter and cause the adapted content item to be displayed on the display according to the modified display parameter. In some embodiments, the processors obtain data indicative of ambient light conditions and adjust the modified display parameter based on the data indicative of ambient light conditions. In some embodiments, the processors cause the adapted content item to be displayed according to the adjusted and modified display parameter.

Abstract: In some implementations, a computing device can perform multi-display alignment through observed user interactions. The computing device can receive user input aligning a first alignment object on a first display device with a second alignment object on a second display device. The computing device can align the display buffers for each display device based on the positions of the alignment objects in each display buffer corresponding to each display device. The computing device can align display buffers based on observed movements of graphical objects between multiple display devices. When display buffers corresponding to the display devices are misaligned, the user may correct the path of a graphical object when moving the graphical object between display devices. The computing device can detect the correction and align the display buffers of the display devices so that graphical objects are presented at the appropriate locations when moved between the display devices.

Abstract: Systems, methods, and computer readable media are described for effectively using dither techniques upon signals having a predicted quantization error that varies across the range of the signal. In some embodiments, predicted error is used to shape a precision input signal so that the newly-shaped signal yields a uniform or relatively uniform predicted quantization error. A dither is applied to the re-shaped signal, and the shaping is reversed, after which the signal may be slope limited and/or quantized, taking full and efficient advantage of the dithering technique.

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.
