1. A method comprising:
detecting a target part of a target object within a sensing range of a contactless capturing device;
triggering, responsive to the detecting, a virtual character display operation, wherein during the virtual character display operation a posture of a virtual character is controlled in real-time based on a relative position of the target object to an image capture element of the capturing device;
animating the virtual character, while the position of the target part relative to the image capturing element is within a preset position range, based on the relative position of the target object to the image capture element of the capturing device; and
capturing an image of the target part when the posture of the virtual character satisfied a preset capturing condition.
