Abstract: A first light beam can be collected by using an optical module. A second light beam can be obtained based on the first light beam. An image sensor can perform photoelectric conversion on the infrared light beam that is in the second light beam and that is irradiated to the first channel to obtain a first electrical signal. Photoelectric conversion can be performed on the visible light beam that is in the second light beam and that is irradiated to the second channel to obtain a second electrical signal. An initial image can be generated based on the first electrical signal and the second electrical signal. A color image and a grayscale image can be sent to an image processor. The image processor can receive the color image and the grayscale image. Fusion processing can be performed on the color image and the grayscale image to obtain a fused image.

Abstract: A method (200) and an apparatus (500) for compensating for brightness of a display panel (140), and a display device (100) are provided. The method (200) for compensating for brightness of a display panel (140) includes: timing a vertical blanking interval (Vblank) in a current frame on the display panel (140) (202); and determining, in response to that a timing time of the vertical blanking interval (Vblank) reaches a first threshold time, a first value used to perform first compensation on brightness of the display panel (140) during the vertical blanking interval (Vblank) in the current frame (204). According to the method (200) for compensating for brightness of a display panel (140), a brightness change caused by current leakage can be compensated for by adjusting a related analog voltage in a timely manner.

Abstract: A communication method and apparatus, to improve SL DRX configuration accuracy. A first communication device receives first information from a second communication device, and send the second communication device an SL DRX configuration corresponding to an SL connection between the first communication device and the second communication device, and the second communication device receives SL transmission from the first communication device based on the SL DRX configuration. In this way, the SL DRX configuration better satisfies a condition of transmission between the first communication device and the second communication device, and energy saving effect of a receive end of the SL connection is enhanced. The first information is used to determine the SL DRX configuration.

Abstract: This application discloses a method and apparatus for implementing entry backup. When a first network device needs to back up information about a first entry stored in the first network device to a second network device, the first network device generates a first BGP message that includes first entry information, and sends the first BGP message to the second network device, where the first BGP message is used to advertise a newly defined entry backup route to the second network device, or the first BGP message includes an extended community attribute. After receiving the first BGP message, the second network device may obtain a second entry based on the first BGP message, and store information about the second entry, where the second entry is a backup entry of the first entry.

Abstract: A display driving apparatus and a display driving method are provided. The display driving apparatus includes a compression and decompression unit, a storage unit, a data selection unit, and a display acceleration unit. When a current frame correlates with a preceding frame, and the current frame is dynamic relative to the preceding frame, the data selection unit obtains a compensated preceding frame by means of calculation according to the current frame, a decompressed current frame, and a decompressed preceding frame, and the display acceleration unit determines an overdrive value according to the compensated preceding frame and the current frame. It may be learned from the foregoing description that no compression error is involved in an overdrive value determining process, an overdrive mechanism may be still used to determine a grayscale value of a displayed pixel. Therefore, display quality of a dynamic image is improved.

Abstract: The present disclosure relates to circuit board reinforcing structures, photosensitive apparatuses, and terminals. The photosensitive apparatus is used in assisted driving, intelligent driving, or autonomous driving. In one example circuit board reinforcing structure, a reinforcing plate of which deformation varies little with temperature is used to suppress warping and deformation of a circuit board caused by a temperature change, so that an impact of the warping and deformation of the circuit board on a location of a photosensitive chip is greatly reduced. In addition, the reinforcing plate and the photosensitive chip are disposed on a same side of the circuit board.
