When the user's finger points to the target object, the terminal can determine the stagnant coordinates of the finger at the top of the terminal screen through the infrared touch screen technology, and then compare the pixel virtual grid inside the terminal screen to determine the target object on the terminal screen. The pixel virtual grid position size is the coordinates and the corresponding image area pixels.

Step S102: Enlarge the target object according to the pixel virtual grid coordinates, the corresponding image area pixels, and the preset enlarged display parameters.

After the terminal acquires the pixel virtual grid coordinates of the target object pointed by the user's finger on the terminal screen and the corresponding image area pixels, the pixel virtual grid coordinates of the target object are first substituted into the linear amplification function, and the enlarged pixel of the target object is calculated.
