  • Patent number: 10726811
    Abstract: An electronic device may have a display such as an organic light-emitting diode display. Electronic devices may also include a number of sensors such as accelerometers and gaze detection sensors. A graphics processing unit (GPU) may render digital pixel values for pixels in the device display. Frames (F2) with long rendering times may cause latency. To reduce latency, an image frame may be displayed for an extended period of time (68) to wait for the subsequent frame (F2) to finish rendering. Once the subsequent image frame (F2) has finished rendering, the subsequent image frame may be displayed without delay. To increase the lifespan of the display, variable persistence may be used. Sensor data and other factors may be used to dynamically determine persistence for minimal motion blur and maximum display lifespan. Sensor data may also be used to determine refresh rates for different portions of the display.

  • Publication number: 20190172399
    Abstract: An electronic device such as a head-mounted device may have displays. The display may have regions of lower (L) and higher (M, H) resolution to reduce data bandwidth and power consumption for the display while preserving satisfactory image quality. Data lines may be shared by lower and higher resolution portions of a display or different portions of a display with different resolutions may be supplied with different numbers of data lines. Data line length may be varied in transition regions between lower resolution and higher resolution portions of a display to reduce visible discontinuities between the lower and higher resolution portions. The lower and higher resolution portions of the display may be dynamically adjusted using dynamically adjustable gate driver circuitry and dynamically adjustable data line driver circuitry.

  • Patent number: 9100581
    Abstract: Samples of a scene are acquired in synchronization with finely interleaved varying conditions such as lighting, aperture, focal length, and so forth. A time-varying sample at each pixel for each condition is reconstructed. Time multiplexed interleaving allows for real-time, live applications, while handling motion blur naturally. Effects such as real-time video relighting of a scene is possible. Time interleaved exposures also allow segmentation of a scene, and allows for constrained special effects such as triangulation matting using a multi-color interleaved chroma key.

  • Patent number: 8619153
    Abstract: A method of calibrating a brightness value measured by a camera with an amount of light received by the camera includes creating a series of measurements, wherein for each measurement the amount of light received at an image plane in the camera is controlled to be a known ratio of two opposed irradiance values: a high irradiance value and a low irradiance value. Each ratio is correlated with the brightness value measured by the camera. A function is obtained describing the correlation.

  • Publication number: 20110304557
    Abstract: Described herein are techniques that offer a class of user-interaction styles for indirect user interaction with a two-dimensional virtual space (“desktop”) using touch-sensitive control surface of a user-input device (such as a mobile phone). Some described techniques enable a user to point, pan and scale within a large virtual two-dimensional space with input from a touch surface of a handheld device, with the output of the user interaction being rendered on a visual display unit (other than the touch surface).

  • Patent number: 7929142
    Abstract: Photodiode-based bi-directional reflectance distribution function (BRDF) measurement is described. Multiple photodiodes are distributed approximately symmetrically at a fixed distance from a surface to be measured. One or more of the photodiodes are directed to emit light, while readings are gathered from the other photodiodes that are not emitting light. The readings are processed based on previously measured calibration data to generate BRDF values.
