Abstract: Embodiments of this application disclose a shooting method and an electronic device, and relate to the field of image processing, to obtain relatively good image quality without manual adjustment performed by a user. A specific solution is as follows: When shooting is started, the electronic device determines a quantity of shot objects and/or a holding state, where the holding state includes a first state in which a display screen is a landscape screen or a second state in which the display screen is a portrait screen. The electronic device sets a shooting parameter based on the determined quantity of the shot objects and/or the holding state, where the shooting parameter is a parameter used when the electronic device performs shooting. The electronic device obtains a first preview image based on the shooting parameter, and displays the first preview image on a display screen.

Abstract: Example methods and systems to perform a migration of a virtualized computing instance and its first snapshot hierarchy from a first object store to a second object store have been disclosed. One example method includes identifying a first disk chain of the first snapshot hierarchy having an object running point, identifying a second disk chain of the first snapshot hierarchy different from the first disk chain, and migrating the second disk chain from the first object store to the second object store to form a first branch of a second snapshot hierarchy in the second object store. After the migrating, the example method includes instructing to take a first native snapshot on the object running point in the second object store, instructing to revert the object running point along the first branch and migrating the first disk chain from the first object store to the second object store.

Abstract: A method of enhancing security in object based datastores is provided. The method mounts first and second datastores identified, respectively, by first and second datastore identifiers. The first and second datastores include, respectively, first and second namespace objects that are mapped to first and second subfolders in the first and second datastores. A first file within the first subfolder references a first object via a first object identifier, while a second file within the second subfolder references a second object via a second object identifier. The first and second objects are tagged with the first and second datastores' identifiers. The first and second datastores share an underlying storage and may be configured to have separate access permissions. The method receives a command to access the first object via a datastore identifier, compares the datastore identifier with the first datastore identifier, and if they match, allows access to the first object.

Abstract: A TOF depth sensing module and image generation method are provided. The TOF depth sensing module includes a light source, a polarization filter, a beam shaper, a first optical element, a second optical element, a receiving unit and a control unit. The light source is configured to generate a beam. The polarization filter is configured to obtain a beam. The beam shaper is configured to obtain a first beam whose FOV meets a first preset range. The control unit is configured to obtain an emergent beam. The control unit is further configured to control the second optical element to deflect, to the receiving unit, a reflected beam obtained by reflecting the emergent beam. In the method, a spatial resolution of a finally obtained depth image of the target object can be improved.

The collimation lens group is located between the array light source and the beam splitter. The control unit is configured to emit light. The collimation lens group is configured to perform collimation processing on beams. The beam splitter is configured to perform beam splitting processing on beams. The receiving unit is configured to receive reflected beams of a target object. By means of the TOF depth sensing module, high spatial resolution and a high frame rate can be implemented in a process of scanning the target object.

Abstract: A laser ranging device includes a laser transceiving apparatus, a rotation apparatus, and a power supply control apparatus. The laser transceiving apparatus is used for transmitting a projection beam to a target to be measured and receiving a reflection beam reflected by the target to be measured. As there are no problems of the reflectivity of the reflector itself and the angle offset of the reflection beam, the light utilization is effectively improved. The rotation apparatus drives the laser transceiving apparatus to rotate by electromagnetic induction transmission, making the laser ranging device smaller in size. The power supply control apparatus supplies power to the rotation apparatus, increasing the service life of the laser ranging device, and the power supply control apparatus transmit data with the laser transceiving apparatus through photoelectric conversion.

Abstract: A technique for managing storage space includes establishing an MSR (minimum space reservation) of a thin file system built upon a storage pool. In response to a set of storage requests to the file system to store new data, the method further includes obtaining an additional space guarantee from the storage pool. After deleting data from the file system such that the size of the file system falls below the MSR, the technique further includes performing a space reclaim operation, the space reclaim operation (i) compacting the file system to a size less than the MSR, (ii) canceling the additional space guarantee such that the storage pool no longer guarantees the additional space for the file system, and (iii) continuing to reserve the full MSR of the file system, even though the size of the file system is smaller than the MSR.

Abstract: Techniques for improving storage efficiency of a data storage system are provided. The techniques include (a) performing a testing operation to evaluate whether a test condition is satisfied for a filesystem having a plurality of subspaces, each subspace being provisioned with a respective amount of storage, each subspace of the filesystem being dedicated to storing different respective types of filesystem content, wherein the test condition indicates that a first subspace has available space in excess of a threshold percentage, (b) in response to determining that the test condition is satisfied for the filesystem, performing a reduction operation on the first subspace to remove a portion of storage provisioned to that subspace while retaining the removed portion for use by the filesystem, and (c) upon a second subspace reaching a fullness threshold, provisioning the removed portion to the second subspace and storing content of the respective type of the second subspace thereon.

Abstract: A light transmitting device has a flexible elongated substantially flat band of high clarity light transmitting polymeric material. An LED is mounted by a mounting structure immediately adjacent but not embedded in an end of the band, and electrical wiring extends from the LED to a battery. The band is incorporated in a container (e.g. backpack, fanny pack, clutch) made at least partially of fabric so that light emitted from the band is visible from the exterior of the container. A battery and printed circuit board are mounted in the interior of the container, and an electrical switch for operating the LED is accessible from the exterior of the container. A flap stitched onto the front panel of the container covers the band and holds it in place but allows light to get through.

At least one battery powers the LED. A module including a printed circuit board, electrical switch, and the LED and battery, is positioned within a housing having open ends so that one or both ends of the light transmitting element receive light directly from an LED. A number of button batteries, or a rechargeable battery with USB port, may be mounted on the module, and the circuitry of the printed circuit board may include an integrated circuit.
