Abstract:
This application provides an imaging method. The imaging method is applied to an imaging apparatus including a color camera and a black-and-white camera, and resolution of the black-and-white camera is higher than resolution of the color camera; and the imaging method includes: obtaining a zoom magnification; simultaneously capturing a color image and a black-and-white image of a target scene, where resolution of the black-and-white image is higher than resolution of the color image; performing cropping processing on the black-and-white image and the color image separately based on the zoom magnification, where the cropped black-and-white image and the cropped color image have a same field of view; and merging the cropped color image and the cropped black-and-white image to obtain an output image of the target scene. Therefore, according to the optical imaging method provided by embodiments of this application, the obtained output image can have a better optical zoom capability.
Abstract:
A heat dissipation system in a box type chassis of a communication device includes an upper heat dissipation channel and a lower heat dissipation channel, which both have an air exhaust vent and an air intake vent, the air intake vent and the air exhaust vent of the upper heat dissipation channel and the lower heat dissipation channel are defined on sidewalls of the box type chassis, and the air intake vent of the upper heat dissipation channel is located above the air exhaust vent of the lower heat dissipation channel. An air baffle is arranged in the box type chassis to generate a circulative airflow in the box type chassis, and therefore, heat dissipated by a circuit board is circulated in the box type chassis through the airflow, the temperature in the box type chassis reaches an extent that prevents vapor from condensing or even becoming a water film.
Abstract:
An image processing method includes segmenting, by a cloud server and based on a zoom ratio of a high-definition image in a high-definition image library, a low-definition image of a small zoom ratio from a terminal to obtain a plurality of image blocks. For each image block, performing, by the cloud server, retrieval and matching in the high-definition image library to obtain one or more high-definition reference images, and then performing, by the cloud server, image quality improvement using an image enhancement network that is based on the high-definition reference images to obtain a plurality of high-definition image blocks. Finally, stitching, by the cloud server, the high-definition image blocks into a super-definition image with higher resolution and higher definition, and returning, by the cloud server, the super-definition image to the terminal.

Abstract:
A method for implementing communication in a WLAN is provided. A routing device receives a packet from an authentication server. The packet carries an identifier of a user terminal and a pairwise master key PMK corresponding to the identifier of the user terminal. The routing device is an endpoint that initiates EAP authentication. The routing device manages the user terminal. The routing device from the packet obtains the identifier of the user terminal and the PMK. The routing device sends a control message to an access controller AC. The control message carries the identifier of the user terminal and the PMK. The AC manages the AP. The user terminal accesses the WLAN by using the AP. The routing device receives a response message from the AC.

Abstract:
Embodiments provide a method and a terminal device for filtering objects. By using the technical solutions provided by the embodiments, the terminal device can display filtered objects, and problems in the prior art that a long time is needed to retrieve subsequent objects and that errors easily occur if the terminal device needs to display a lot of objects can be avoided, thereby effectively increasing the efficiency and reliability of displaying objects.
Abstract:
In a reverse address resolution method, a sender electronic device broadcasts a first request packet. An Ethernet payload of the first request packet includes a media access control (MAC) address of a target electronic device. After receiving the first request packet, the target electronic device determines that an IP address of the target electronic device is requested, and returns a first reply packet. An Ethernet payload of the first reply packet includes the internet protocol (IP) address of the target electronic device. According to the technical solutions provided in this application, the sender electronic device obtains the IP address of the target electronic device based on the MAC address of the target electronic device through interaction at a data link layer. Therefore, in a mobile distributed system, the IP address of the target electronic device is quickly obtained without relying on a server.
Abstract:
A media playing method-includes: receiving a first play request of an application, where the first play request includes a first identifier; sending a first address to the application, where the first address is a local uniform resource locator URL address; buffering, from a server device to a client device, a target media resource that is in the server and that corresponds to the first identifier; and sending, when receiving a second play request sent by the application program to the first address, the buffered target media resource to the application program for playing.
