  • Patent number: 11350030
    Abstract: In one embodiment, a computing system receives one or more signals indicative of light intensities captured by one or more cameras. These signals are captured in a plurality of frames at a first frame rate. The computing system calculates light intensity metrics for each frame of the plurality of frames based on the one or more signals captured in the respective frames. The computing system detects one or more peaks based on the light intensity metrics associated with one or more frames of the plurality of frames. The one or more frames were captured in a predetermined time period. The computing system determines a likelihood of perceptible flicker based on the detected one or more peaks. The computing system generates a notification indicating the likelihood of perceptible flicker in response to a determination that the likelihood of perceptible flicker exceeds a predetermined threshold.

  • Patent number: 9851773
    Abstract: Embodiments relate to a method for allocating resources and settings in order to optimize application satisfaction in view of hardware resources and adjustable software configurations. As applications are executed on a computing device, usage data is tracked, adjustable settings are identified, and power consumption of each application under different settings is measured. The usage data is then compiled, an optimal configuration setting is assessed for each application, and the setting is conveyed and applied to one or more applications.

  • Patent number: 9787978
    Abstract: There are disclosed various methods, apparatuses and computer program products for testing a display. In some embodiments an image sensor captures a rendered image from the display to form a captured image, the image sensor having a second resolution greater than the first resolution. The captured image is analyzed to find difference of orientation of the rendered image with respect to an orientation of the image sensor. A rotated image is formed on the basis of the analyzed difference of orientation to obtain orientation for the rotated image to correspond with the orientation of the image sensor. The rotated image is resampled to form a resampled image having the first resolution.
