  • Patent number: 11005909
    Abstract: Systems and methods are described herein for providing content during reduced streaming quality. Data streaming is susceptible to degradation in quality that adversely affects the delivery of content. For example, sufficient reduction in streaming quality can cause video and audio portions of a data stream to become unsynchronized. In place of displaying a buffering notification, the system displays a previously stored video frame that the system determines is a suitable replacement for the currently streamed video frame that is affected by the sufficiently reduced streaming quality.

  • Patent number: 10812777
    Abstract: Described is an imaging component that utilizes two rolling shutter sensors for motion detection of objects and for depth mapping of objects within an effective field of view of the imaging component. Unlike traditional stereo cameras that utilize global shutter sensors to avoid distortions, or attempting to remove distortions created by rolling shutter sensors, the disclosed implementations emphasize the distortions created by rolling shutters imaging moving objects and utilize that information to determine that the objects are moving and/or to determine a range or distance of the object from the imaging component. For example, a first rolling shutter sensor is oriented in a first orientation such that the scanlines generate the image from a top of the sensor to the bottom of the sensor, and a second rolling shutter sensor is oriented in a second orientation such that the scanlines generate the image from a bottom of the sensor to the top of the sensor.

Another data stream at a higher resolution than each of the additional data streams may then be generated by combining elements (e.g., pixels) of the additional data streams.

  • Patent number: 10187581
    Abstract: An image pickup apparatus which satisfactorily compensates for a flash band appearing due to an external flash and prevents a row insensitive to the flash from appearing in a corrected image. The flash band appearing in a plurality of frames consecutive in terms of time is detected based on an image signal output from an image pickup device which sequentially starts exposure and sequentially reads out signals for each row of pixels. An image in at least one of those frames is corrected to a full-screen flash image. When a width of the flash band is smaller than the number of rows in one frame, a row in which the flash band does not appear is interpolated using a row in which the flash band appears and which immediately precedes or immediately succeeds the row in which the flash band does not appear.
