1. A digital photographing method comprising: generating a frame image including a plurality of objects; locating each of the plurality of objects in the frame image; detecting motion vectors of the plurality of objects; detecting a distance between the motion vectors of the plurality of objects; determining whether the motion vectors meet a predetermined condition; and generating an image capturing signal when the motion vectors meet the predetermined condition, wherein the predetermined condition is met if the distance is within a reference distance range and if the distance is within the reference distance range, the image capturing signal is generated at a timing when the distance is within the reference distance range, and a desired timing image is captured according to the image capturing signal.
