Provided is a smart terminal with a built-in screenshot function, including a sensing module and a processing module. The sensing module is configured to sense a touch of a user to form a coordinate of a touch point, and send the formed coordinate of the touch point to the processing module. The processing module is configured to receive the coordinate of the touch point, and process the coordinate of the touch point to form a capture area and capture the capture area. In the meanwhile, a method for implementing a smart terminal with a built-in screenshot function is provided. By using a technical solution of the present disclosure, it is not necessary to remember a button combination or capture a screen content a full-screen display situation, thereby facilitating an operation of a user.
