Abstract
This application provides a mirroring method, an apparatus, and a system. In the method, in a process in which an electronic device such as a mobile phone or a tablet and a large-screen device share an image resource through mirroring, a color gamut of a collected image resource may be converted into a color gamut obtained through negotiation between the electronic device and the large-screen device, the converted image resource may be sent to the large-screen device, and the large-screen device displays the image resource in the negotiated color gamut. According to the technical solutions provided in this application, the large-screen device may use a dynamic adaptive optimal color gamut during mirroring, that is, a color difference between the image resource displayed on the electronic device and the large-screen device may be reduced in the mirroring process. This improves users' visual experience during mirroring.
