  • Patent number: 10277829
    Abstract: In scenes that have low lighting, it may be difficult for a personal electronic device to capture video images that meet a scene lighting criteria. In some low-lighting situations, the receiving party may be unable to sufficiently see the face of the party that they are videoconferencing with. Described herein are techniques for utilizing a device's display to illuminate the scene surrounding the device. Improved lighting may come from global display adjustments, local display adjustments that do not alter the display's contents (other than to change their brightness levels), and/or local display adjustments that alter the display's contents. In some embodiments, background elements on a device's display may be identified for brightening in a first attempt to meet the scene lighting criteria without negatively impacting foreground scene content. If such approaches are unsuccessful, the device may next replace one or more regions of displayed content with regions of brightened pixels.

  • Publication number: 20180352156
    Abstract: Techniques disclosed herein permit a party to identify a first (low-resolution) image as it is displayed on their, for example, smart phone during a video conference call. Identifying information specific to the first image may be collected and a request for a high-resolution copy of the image sent to the party sourcing the transmitted image. The high-resolution image may be sent from the image's sourcing device to the requestor's device during, or after, the video conference call. In some embodiments, the high-resolution image may be sent through an alternate communication channel (e.g., via a chat, social media or email channel). In other embodiments, the high-resolution image may be sent to a network-based service from which the requestor may obtain the image. In one embodiment, the sourcing device may message the requesting device that the image has been sent to the network-based service.

  • Patent number: 9696371
    Abstract: A test method and system for cut-in voltage. The method comprises: coarse scanning of the cut-in voltage: a grid voltage, i.e., the cut-in voltage, is quickly determined when a drain terminal current is greater than a target current for the first time (100); accurate scanning of the cut-in voltage: a scanning step length is shortened continuously until the scanning step length is shorter than a preset step length, and each time the scanning step length is shortened, the scanning is conducted according to the current shortened scanning step length on the basis of the cut-in voltage determined in the former time, and then the cut-in voltage under the condition of the current shortened scanning step length is determined again (200). The scanning voltage is automatically increased or decreased by the test method and system through adding high resolution and high precision test conversion into a second scanning test, and therefore the testing of the cut-in voltage becomes more efficient and more accurate.
