Abstract: A screenshot method includes that a terminal responds to a non-stylus operation by entering a screenshot waiting state. When the terminal establishes a connection to the stylus, the terminal detects an operation of the stylus on a touchscreen of the terminal. If an operation of drawing a closed figure with the stylus is detected, the terminal takes a screenshot of interface content in the closed figure drawn with the stylus.

Abstract: A first electronic device receives a projection interface of a first application from a second electronic device, and displays the projection interface. The first electronic device receives a first input and a second input that are in the projection interface and that are of a stylus pen used by a user, and displays an updated projection interface. The updated projection interface includes a first layer and a second layer. The first layer includes a first image that includes a first handwriting trajectory and that is generated by the second electronic device based on the first input; and the second layer includes a second handwriting trajectory that is locally drawn by the first electronic device based on the second input.

Abstract: A terminal provided in the present disclosure, acquires values of one or more monitoring parameters. The terminal sets, according to the monitoring parameter, a blue light output value of a to-be-adjusted pixel displayed on a screen of the terminal when a value of at least one of the monitoring parameters meets a preset rule corresponding to the monitoring parameter, where the blue light output value is less than an original blue light output value of the to-be-adjusted pixel. The screen of the terminal displays the to-be-adjusted pixel according to the blue light output value such that the terminal can set, according to the monitoring parameter, the blue light output value of the to-be-adjusted pixel displayed on the screen of the terminal, and therefore the blue light can be adjusted intelligently, and an objective of vision protection without affecting user experience is achieved.
