Claim 13:
14. An electronic device, comprising:
a processor; and
a memory for storing instructions executable by the processor;
wherein the processor runs the executable instructions to:
determine a target object contained in a first image captured by the camera;
crop an image area from the first image, wherein the image area contains the target object; and
enlarge the image area to a predefined preview size, and preview and display the enlarged image area in a shooting preview interface;
wherein the processor runs the executable instructions to:
display the first image while the enlarged image area is being displayed, and mark the target object in the first image, wherein a display area of the first image is a changeable area that can be moved or scaled according to a user operation, and the first image is overlaid on the enlarged image area;
wherein the processor runs the executable instructions to:
generate a second prompt message under a circumstance where the target object moves out of the first image, wherein the second prompt message is used to indicate such a movement of the head-mounted device that a first image re-captured by the head-mounted device after the movement contains the target object;
wherein the processor runs the executable instructions to:
acquire device movement information recorded by a posture sensor carried in the head-mounted device, wherein the device movement information is used to record a corresponding historical device movement direction of the head-mounted device when the target object moves out of the first image; and
generate the second prompt message containing a first movement direction, wherein the first movement direction is an opposite direction of the historical device movement direction;
or,
acquire object movement information of the target object, wherein the object movement information is used to record a corresponding historical object movement direction of the target object when it the target object moves out of the first image; and
generate the second prompt message containing a second movement direction, wherein the second movement direction is a same direction as the historical object movement direction.
