Abstract: A display method, an apparatus, and a storage medium are provided. The method includes: rendering, by a first container, a to-be-displayed page to generate to-be-displayed image data, and encrypting the image data; and writing, by the first container, encrypted image data into a buffer corresponding to the first container, and sending instruction information to a second container of a terminal, where the instruction information is used to instruct the second container to securely display the encrypted image data. Because the containers are isolated from each other, the malware in the first container cannot access the image data displayed in the second container, and the second container securely displays the encrypted image data. In this way, security of displaying the image data can be improved while ensuring that an image display function is not restricted.

Abstract: The present application discloses an image processing method and apparatus, and an electronic device, and pertains to the field of image processing. The method includes: obtaining an inter-frame residual between two adjacent image frames to obtain a residual block; determining, based on the residual block, a target pixel region on which super-resolution processing needs to be performed; and performing super-resolution processing on the target pixel region to obtain a target pixel region. For another pixel region, the super-resolution processing result of an image frame that is in the two image frames and on which super-resolution processing is performed is used. This application reduces high computation costs of super-resolution processing.

Abstract: An image processing method, where, in the method, a special image filter is generated, and super-resolution is performed on an image based on the image filter. The image filter includes filter parameters corresponding to each pixel in an image that requires super-resolution processing, and pixels with different texture features correspond to different filter parameters. The image super-resolution method, apparatus, device, and the like may be applied to various scenarios such as a video, a game, and photographing.

Abstract: This application discloses a multi-container-based trusted application processing method and a related device, to simplify a trusted application development and deployment process, and improve trusted application processing efficiency and security of an access interface of a trusted execution environment. The method of this application includes: performing, by a terminal, an integrity check on a signed security computation unit by using a security computation container, if the signed security computation unit succeeds in the integrity check, performing, by the terminal, a validity check on the signed security computation unit by using the security computation container, and obtaining a check result; and if the check result is valid, loading, by the terminal, the signed security computation unit by using a trusted execution environment (TEE) or a secure element (SE), and obtaining a security computation result of a trusted application.
