Abstract

A method and a computing device for adjusting the display of an image, where the method includes: obtaining, during a process of playing an image, a finger gesture for processing the image; determining whether the finger gesture is a finger gesture for adjusting the image, the adjusting including rotating or flipping; and adjusting the image according to the finger gesture if the finger gesture is a finger gesture for adjusting the image. After it is determined that a finger gesture for processing an image is a finger gesture for adjusting the image, the image is adjusted according to the finger gesture, and during this process, a touch screen device body does not need to be moved, which is a convenient implementing manner; moreover, the image can be rotated or flipped, supporting different operations on the image.

detecting a first single-finger gesture on the touch screen that exceeds a first threshold speed and is less than a second threshold speed, wherein (i) the first threshold speed is greater than zero, and (ii) the first single-finger gesture starts at a first position on the touch screen, continues to a second position, different from the first position, on the touch screen, and ends at the second position on the touch screen;

in response to detecting the first single-finger gesture on the touch screen that is less than the second threshold speed, maintaining the original image on the touch screen at the current orientation;

detecting a second single-finger gesture on the touch screen that exceeds the second threshold speed, wherein the second single-finger gesture also starts at the first position on the touch screen, continues to the second position on the touch screen, and ends at the second position on the touch screen;

in response to detecting the second single-finger gesture on the touch screen that exceeds the second threshold speed;

calculating an orientation of the second single-finger gesture based on the first position and the second position;
