Abstract: Imaging systems and techniques are described. An imaging system causes a display to display light according to a predefined pattern. The imaging system receives image data of a scene from an image sensor. The image data is captured using the image sensor while the display is configured to display the light according to the predefined pattern. The imaging system processes the image data to generate at least one image frame of the scene based on detection of the predefined pattern in the image data. The imaging system outputs the at least one image frame of the scene.

Abstract: An example image capture device includes memory and one or more processors coupled to the memory and a camera sensor. The camera sensor is disposed to receive light through at least a portion of a display. The one or more processors are configured to determine an effective aperture for the camera sensor. The one or more processors are configured to apply a mask to one or more pixels in the at least a portion of the display, wherein the mask is based on the effective aperture. The one or more processors are configured to capture an image using the camera sensor.

Abstract: A device may allocate one or more frame buffers. In response to a command to open an application after allocating the one or more frame buffers, the device may reassign one or more of the frame buffers to the application. Furthermore, the device may store, based on instructions of the application, content data in the one or more reassigned frame buffers. The device may output, for display on a display screen, content based on the content data in the one or more reassigned frame buffers.

Abstract: Apparatuses, systems, and methods are provided for use with expandable displays. In some implementations management techniques and/or systems are provided that allow for access to expandable display functionality to be managed to as to potentially prolong device battery life. In other or additional implementations, techniques and/or systems are provided for potentially safeguarding devices with expandable displays from damage in the event of a fall or drop event. In yet other or additional implementations, techniques and/or systems are provided for determining the expansion state of an expandable display, thereby allowing corrective measures to be taken if the actual expansion state of the expandable display does not align with the expected expansion state of the expandable display.

Abstract: Certain aspects of the present disclosure provide a method for driving a plurality of display panels including a first display panel and a second display panel. The method includes receiving a first synchronization signal from the first display panel. The method further includes receiving a second synchronization signal from the second display panel. The method further includes determining a phase difference between the first synchronization signal and the second synchronization signal. The method further includes computing at least one phase shift offset based on the determined phase difference, the at least one phase shift offset being configured to reduce the phase difference between the first synchronization signal and the second synchronization signal. The method further includes providing a first phase shift offset of the at least one phase shift offset to the first display panel. The method further includes providing a unified synchronization signal to a display processor.
