Abstract: Certain aspects of the present disclosure provide methods and apparatus for generating, in a display panel, a virtual mask layer around a cutout region for a front camera. The front camera may be positioned under the display panel and receive light through the cutout region. The mask layer may hide defects of the cutout region that does not have functional pixels. The disclosed techniques may improve aesthetic appearance of displays having punch-hole cameras with reduced hole sizes and increased production quality conformance rate.

Abstract: Aspects of the present disclosure can receive a hardware Vsync signal from a display, generate a hardware timestamp signal based on the hardware Vsync signal, determine an error for a pulse in the hardware timestamp signal, determine whether the error for the pulse is over a threshold, synchronize a software Vsync signal based on the hardware timestamp signal, wherein the pulse of the hardware timestamp signal is ignored in synchronization based on whether the error is above the threshold, and control rendering and transmission of a frame to the display based on the synchronized software Vsync signal.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment receives a sliding window of measurements associated with a radar signal transmitted by the UE; determines that a user is within a threshold distance of the UE, wherein the threshold distance is determined to be a first distance when an energy measurement, associated with the radar signal, indicates an energy reduction satisfying a threshold energy reduction, or wherein the threshold distance is determined to be a second distance when the sliding window of measurements indicates an amount of energy variation satisfying a threshold amount of energy variation associated with the radar signal; and performs, based at least in part on determining that the user is within the threshold distance, an action associated with a communication signal of the UE. Numerous other aspects are provided.

Abstract: An example image capture device includes a display configured to display captured images, a camera sensor, the camera sensor being disposed to receive light through at least a portion of the display, memory configured to store captured images, and one or more processors coupled to the camera sensor, the display, and the memory. The one or more processors are configured to receive a signal from a sensor. The one or more processors are configured to determine, based at least in part on the signal, a user interface mode. The user interface mode includes a first mode having a first number of black pixels or a second mode having a second number of black pixels. The first number is greater than the second number. The one or more processors are also configured to receive image data from the camera sensor.

Abstract: A video processing system includes a graphics subsystem including a graphics processing unit (GPU) and a frame buffer. The GPU is configured to obtain a physical pixel layout corresponding to a display architecture of an electronic display, wherein the physical pixel layout is characterized by a non-uniform subpixel arrangement; receive image data, including a matrix of logical pixel chroma values; subsample the matrix of logical pixel chroma values according to the physical pixel layout to produce subsampled image data having a subpixel rendered format corresponding to the non-uniform subpixel arrangement; store the subsampled image data in the frame buffer; and enable transfer of the subsampled image data to a display processing unit (DPU) of the electronic display for composition of frames having the non-uniform subpixel arrangement.

Abstract: Methods, systems, and apparatuses are provided to automatically adjust the position of image sensors, and generate a multi-view image based on image data captured from the image sensors. For example, an image capture device includes a housing comprising a first housing portion and a second housing portion, with a first sensor coupled to the first housing portion, and a second sensor coupled to the second housing portion. A coupling device, such as a hinge, couples the first housing portion to the second housing portion. The image capture device obtains image data from the first sensor and the second sensor, and determines an object depth based on the obtained image data. The image capture device outputs an adjusted angle based on the object depth, and obtains additional image data from the first and second sensors. The image capture device generates the multi-view image based on the additional image data.

Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may adaptively switch between hybrid automatic repeat request (HARQ) monitoring modes to support power savings. In a first HARQ skipping mode, the UE may transmit an uplink message corresponding to a HARQ identifier and may receive a positive acknowledgment (ACK) message in a HARQ monitoring occasion associated with the HARQ identifier. Upon receiving the ACK message, the UE refrains from monitoring a subsequent HARQ monitoring occasion associated with the HARQ identifier while in the first HARQ skipping mode (e.g., an aggressive HARQ skipping mode). The UE may periodically enter a periodic evaluation mode from the first HARQ skipping mode, in which the UE monitors a subsequent HARQ monitoring occasion after receiving an ACK message to check for false ACK messages. If a false ACK message is detected, the UE enters a first HARQ skipping prohibited mode.

Abstract: Methods, systems, and devices for wireless communications are described. In some systems, a user equipment (UE) may perform calibration of a transceiver chain to maintain or improve operation of a device or comply with legal or protocol requirements. The UE may receive one or more wireless signals indicating a first set of resources where the first device is scheduled to transmit or receive communications. The UE may calibrate a wireless transceiver chain of the first device in a second set of resources. The second set of resources excludes the first set of resources and includes at least a portion of a third set of resources. The third set of resources are resource in which the first device has an option to transmit or receive communications based on a protocol configuration.

Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may run a process associated with a low latency. As such, the UE may operate in a mode to stay in a connected state with a network. The mode may include transmitting a keep alive message. Such message may be transmitted based in part on a keep alive timer with a shorter duration than a network traffic inactivity timer. If no communications occur between the UE and the network by the expiration of the keep alive timer, the UE may transmit a keep alive message to the network to maintain the connected state and reset the keep alive timer. Alternatively, if communications do occur, the UE may reset the keep alive timer. If the process is terminated, the UE may exit the mode for staying in the connected state, which may include canceling the keep alive timer.
