Abstract

The invention provides a display device and a data sharing method. The display apparatus includes a display and a controller. Wherein the controller is configured to construct a virtual device node when a calling request which is sent by a first camera application and is used for calling a camera is received; storing image data acquired by the camera in a physical memory; mapping the image data from the physical memory to a first virtual memory by using a device node of the camera, wherein the first virtual memory is used for providing the image data for a first camera application; and mapping the image data from the physical memory to a second virtual memory by using the virtual device node, the second virtual memory being used for providing the image data to a second camera application. The image data acquired by the camera can be simultaneously sent to a plurality of camera applications, so that data sharing among the plurality of camera applications is realized. Therefore, the user can use a plurality of camera applications at the same time, and the user experience is improved.

Description

technical field [0001] The present application relates to the technical field of display devices, in particular to a display device and a data sharing method. Background technique [0002] With the rapid development of display devices, the functions of display devices will become more and more abundant, and the performance will become more and more powerful. It can realize two-way human-computer interaction function, integrate audio-visual, entertainment, data and other functions into one, to meet the needs of users. Diverse and individual needs. The display device can have a built-in or external camera device to realize specific functions such as video chatting, taking pictures, and recording. [0003] The display device may be installed with a camera application that needs to use the camera, such as "video call" and "mirror". After the display device starts the camera application related to the camera, it can use the camera to obtain multiple frames of image data, genera...
