An image capturing method is provided, especially adaptable in a camera. First, a composition profile for a picture to be taken, is configured. The composition profile defines the number of objects to be included in the picture, and positions and sizes of each object. Thereafter, a sensor in the camera is enabled to receive an image, and simultaneously, it is determined whether the image satisfies the composition profile. If the image satisfies the composition profile, the image is stored to be the picture.
