Image preview method and apparatus, electronic device, and storage medium

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.
