Abstract: A display method. The display method is applied to a control terminal, and the control terminal is used to communicate with an imaging device. The imaging device includes a wide-angle lens and a zoom lens, and the control terminal includes a display interface. The display method includes displaying an image obtained by the wide-angle lens in the display interface, obtaining a first user operation acting on the display interface, and displaying a first detail imaging area in the display interface in response to the first user operation. The first detail imaging area is being used to display an imaging range of the zoom lens.

Abstract: Methods and devices for providing notifications. Under conventional techniques, users often forget relationship between multiple windows. This results in poor user experience. The implementations include displaying a first association identifier on a tab of the second window after determining the second window associated with the first window, and displaying a first association identifier on a tab of the second window. Accordingly, the user knows the relationship between these windows without reading the content of the windows. This improves user experience.
