Image-capturing system and method thereof

An image-capturing system, comprising:

• a first image-sensing module, configured to sense a scene that a user is photographing;
• a second image-sensing module;
• a processor, configured to detect a plurality of objects in the scene sensed by the first image-sensing module and to attach a plurality of labels to the detected objects;
• and
• a display panel, configured to display a preview image of the sensed scene with the labels of the detected objects for the user to select,
• wherein the first image-sensing module is further configured to track and focus on a first object of the detected objects selected by the user to capture a first image, and the second image-sensing module is configured to track and focus on a second object of the detected objects selected by the user to capture a second image,
• wherein the processor is further configured to fuse the first image and the second image into a resulting image in which the first and the second objects are in focus.
