The imaging device can include an imager to form an image of an object viewed by the imaging device; a display interface to display the object; a focus control to adjust a focus of the object displayed; a hardware processor; and a memory storing computer-readable instructions, the instructions executable by the hardware processor to perform operations. The operations can include receiving an indication of a change in focus state of the image; performing image processing on the image; determining a focus state of the object based on the image processing; comparing the focus state of the object to the focus state of the object in a previous image; indicating a focus state of the image on the display; and receiving a focus input to increase the focus.

Abstract: A method for determining a prediction block for decoding or encoding a current block in a current picture of a video stream. The method includes obtaining a pair of initial motion vectors comprising a first and a second initial motion vector. The method also includes determining whether to refine the initial motion vectors. The step of determining whether or not to refine the initial motion vectors comprises: i) determining whether a first prediction scheme and/or a second prediction scheme is enabled and ii) determining to refrain from refining the initial motion vectors as a result of determining that either the first prediction scheme or second prediction scheme is enabled or determining to refine the initial motion vectors as a result of determining neither the first prediction scheme nor second prediction scheme is enabled.

To efficiently code residual blocks obtained from block-based motion compensation, a video encoding apparatus and the video decoding apparatus divide a relevant residual block of a current block into two subblocks in a horizontal or vertical direction and encode one residual subblock alone out of the two residual subblocks.

Abstract: A method for encoding a video stream includes obtaining images of a scene captured by a camera at a first resolution; identifying regions of interest (ROIs) in an image; adding, as part of an encoded video stream, a first video frame encoding at least part of the image at a second resolution lower than the first resolution; adding a second video frame marked as a no-display frame, and being an inter-frame referencing the first video frame with motion vectors for upscaling of the ROIs; adding a third video frame encoding the ROIs at a third resolution higher than the second resolution, and being an inter-frame referencing the second video frame.

Abstract: Innovations in the area of prediction of block vector (“BV”) values improve encoding or decoding of blocks using intra block copy (“BC”) prediction. For example, some of the innovations relate to use of a default BV predictor with a non-zero value. Other innovations relate to use of a selected one of multiple BV predictor candidates for a current block. Still other innovations relate to use of a skip mode in which a current intra-BC-predicted block uses a predicted BV value.

Abstract: Devices, networks, systems, methods, and processes for detecting and mapping Low Latency, Low Loss, and Scalable throughput (LAS) traffic are described herein. A device may determine that a data flow is LAS. The device can determine an initial Quality of Service (QoS) value associated with the data flow. The device may determine one or more network policies associated with one or more QoS levels. The device can determine a QoS ceiling value associated with a highest QoS level of the one or more QoS levels. The device may mark the data flow with the QoS ceiling value if the initial QoS value is lower than the QoS ceiling value, thereby mapping the data flow to the highest QoS level. The device can also maintain the initial QoS value if the initial QoS value is greater than the QoS ceiling value, as an exception to the one or more network policies.

Abstract: Methods and devices for encoding, decoding and transmitting a three-dimensional scene initially represented as a multiplane image (MPI) are provided. Each layer of the MPI is split into patches based on the transparency component. Patches of a layer are grouped in a tile. The greater the depth of the layer, the greater the identifying number of the tile. When several tiles are packed in an atlas image, the same monotonic (i.e. ascending or descending) function according to depth applies to atlas numbers. At the decoding side, the current viewport to render is initially cleared and each decoded tile is sequentially blended over from the nearest one to the furthest due to the numbering of the set of atlases and tiles. Pixels of a patch under rendering are projected onto pixels of the viewport image according to the depth of the tile comprising the patch and metadata indicating the position of the patch in the layer of the MPI the patch has been clustered from.

Abstract: A system utilizes a hybrid chroma subsampling process in which a source device generates a plurality of motion layers from an input image of a video stream. Each motion layer is associated with a different motion criterium and includes data from the image only for those regions of pixels that meet the corresponding motion criterium. The source device generates each motion layer with a different degree of chroma subsampling based on the motion criterium associated with the motion layer. The resulting plurality of motion layers are transmitted to a sink device. The sink device decodes the motion layers and then generates a composite image from the resulting motion layers, the composite image representing the input image with different degrees of chroma subsampling for different regions based on the degree of motion in each region.

A numerical aperture (NA) of the light beam from the display apparatus is smaller than a maximum value and larger than a minimum value of an NA of the light beam from the sample, at a position of an image on an optical path that is formed after the light beams from the sample and the display apparatus are combined by the combining optical element.

Abstract: Methods, systems, and devices for wireless communications are described in which full-duplex communications may be configured at a serving network entity. One or more symbols of a set of symbols may be configured for full-duplex communications at the network entity, and at least a first symbol that is configured for full-duplex communications also may be configured for synchronization signal block (SSB) transmissions according to a SSB configuration. A user equipment (UE) that is configured to monitor the first symbol for a SSB may use a priority rule to determine whether to transmit an uplink communication on the first symbol, or to monitor for the SSB on the first symbol. Additionally, or alternatively, a UE may transmit capability information that indicates whether the UE supports the full-duplex operation configured in SSB symbols.
