1. A method for auto-focusing of an electronic device, the method comprising: collecting sensor information using a plurality of sensors of the electronic device when a camera of the electronic device is driven, selecting a first sensor for determining a direction of a subject and a second sensor for determining a distance to the subject among the plurality of sensors based on the collected sensor information, obtaining a first information from the selected first sensor and a second information from the selected second sensors, and focusing on the subject located in an image collected from the camera using the obtained first information and second information, wherein the collected sensor information comprises at least one of a photographing environment, a characteristic of a sensor, or a photographing mode, and wherein the selecting of the first sensor and the second sensor comprises: calculating an accuracy point and a weight of each of the plurality of sensors based on the collected sensor information, and selecting, as at least one focusing sensor, the first sensor and the second sensor among the plurality of sensors, having a highest value based on the calculated accuracy point and weight.
