Description

Camera sharing methods, devices, equipment and media This application claims priority to Chinese Patent Application No. 202411516947.8, filed on October 28, 2024, entitled "Camera Sharing Method, Apparatus, Device and Medium", the entire contents of which are incorporated herein by reference. Technical Field This invention relates to the field of image processing technology, and more specifically, to a camera sharing method, apparatus, device, and medium. Background Technology With the rapid development of economy and technology, wearable devices, especially head-mounted devices (such as AR, VR, MR and XR smart glasses or helmets), are widely used in various fields. Multiple applications running simultaneously is a typical application scenario in head-mounted displays (HMDs), where multiple applications run in the foreground on the HMD simultaneously. In this scenario, the HMD may simultaneously run at least two processes that need to access the same camera. For example, it might run both a 6DoF algorithm and a gesture algorithm simultaneously, or it might run both a camera app and a QR code scanning app simultaneously. However, when a head-mounted device simultaneously launches at least two processes that need to access the same camera, once that same camera is accessed by one process, it cannot be accessed by other processes. This results in at least two processes that need to access the same camera being unable to simultaneously obtain camera data, or the camera function of the later-launched process becoming invalid.
