Patent number: 11385781Abstract: 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.Type: GrantFiled: September 24, 2020Date of Patent: July 12, 2022Assignee: Apple Inc.Inventors: Kenneth I.

Patent number: 11062435Abstract: 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.Type: GrantFiled: November 11, 2019Date of Patent: July 13, 2021Assignee: Apple Inc.Inventors: Ian C.

Patent number: 10672363Abstract: 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.Type: GrantFiled: September 28, 2018Date of Patent: June 2, 2020Assignee: Apple Inc.Inventors: Gabriel Marcu, Ian C.

Patent number: 10321164Abstract: 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.Type: GrantFiled: September 23, 2016Date of Patent: June 11, 2019Assignee: Apple Inc.Inventors: Kenneth I.
