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 only the target pixel region to obtain a target pixel region after the super-resolution processing. For another pixel region, a super-resolution processing result of an image frame that is in the two image frames and on which super-resolution processing is performed is directly used. This application can resolve a problem of high computation costs of super-resolution processing.
